Description

【０００１】
【発明の属する技術分野】
本発明は、エミッションＣＴ、即ちＳＰＥＣＴ（Single Photon Emission Computed Tomography）、ＰＥＴ（Positron Emission Tomography）等を運用する医療施設（本明細書において「ＰＥＴ施設」という）のレイアウトに関する。
【０００２】
【従来の技術】
放射性核種をトレーサーとし、その体内分布を断層撮影することで、動態機能検査、体内細胞の代謝量を観ることができるＰＥＴ検診により、ガンの早期発見の確率は格段に高まる。がん診断を行う¹⁸Ｆ−ＦＤＧ（Fluoro Deoxy Glucose）検査にも保険が適用され、今後ＰＥＴ検診の需要は飛躍的に増大すると予想されている。ＰＥＴ検診の需要の増大に伴い、医療従事者（医師、放射線技師、看護師等）の被曝線量低減が重要な課題となる。
【０００３】
ＰＥＴ検診では、処置室にて被検者に放射性薬剤を投与後、放射性薬剤の体内分布の定常化のため５０分程度安静室にて待機させた後、トイレにて排尿させ、ＰＥＴカメラのある撮影室に移動して撮影を行う。場合によっては投与した放射性核種の減衰を待つため、６０分程度回復室にて待機させて検査を終了する。他の放射線施設と異なり、線源となる被検者が放射線管理区域内を大きく移動する。放射性薬剤を投与直後の被検者の体表面における線量率は、およそ数百μSv/hになる。医療従事者が被検者の近傍に長時間滞在した場合、放射線障害防止法に定められた年間の線量限度（最大年間５０mSv）を超える畏れがある。
そこで、医療従事者の被曝線量を低減するためには、被検者と医療従事者との接近を避け、被検者の動線と医療従事者の動線を分離する必要がある（例えば非特許文献１参照）。

【発明が解決しようとする課題】
ところで、ＰＥＴ施設の効率的な運用を図るためには、毎日医療業務に従事する医療従事者の動線を短縮する必要があるが、従来のＰＥＴ施設では、被検者数が少ないこと等の理由もあり、このような配慮がなされているとは必ずしもいえなかった。
【０００６】
そこで、本発明は、医療従事者の被曝線量を低減しつつ、医療従事者の動線を短縮化し、ＰＥＴ施設の運用効率の向上を図ることを主たる目的とする。
【０００７】
【課題を解決するための手段】
前記課題を解決するため、本発明は、医療従事者の動線をＰＥＴ施設内の中央に配置し、被検者の動線をＰＥＴ施設内の外周に配置した。具体的には、操作室・読影室と処置室をＰＥＴカメラ室及び操作室・読影室を隣接・近接させ、その周囲に被験者用通路を設置する。これにより、被検者と医療従事者の動線が分離され、医療従事者の被曝線量を低減することができ、さらに、医療従事者の動線を短縮する。その他の解決手段については、次の発明の実施の形態で明らかにする。
【０００８】
【発明の実施の形態】
以下、本発明のＰＥＴ施設の実施形態を、図面を参照して本発明の実施の形態を詳細に説明する。
【０００９】
≪第１実施形態≫
まず、第１実施形態のＰＥＴ施設を説明する。
図１〜図３は、第１実施形態のＰＥＴ施設を示す図であり、建屋面積や敷地面積を削減するために、複数階構造としたＰＥＴ施設の建屋のレイアウトを例示する。このうち、図１は、サイクロトロン等重量物が配置される下層階の平面図である。図２は、ＰＥＴカメラが設置される上層階の平面図である。なお、図面上、放射線の非管理区域はハンチングを施して、管理区域と容易に区別できるようにしている。
【００１０】
〔１階のレイアウト〕
図１に示すように、第１実施形態のＰＥＴ施設Ａの下層階（以後１階として説明する）の管理区域には、ホットラボ１０、放射性薬剤検定室１１、サイクロトロン室１３、電源機械室１４、空調排水処理室１５、廃棄物保管室１６、医療従事者用階段２７等を配置した構成（レイアウト）をしている。
【００１１】
このうち、ホットラボ１０は、図示しない合成装置や自動分注装置等が備えられており、サイクロトロン２３で生成した放射性核種からＰＥＴ検診に用いる放射性薬剤の合成・分注等、放射性薬剤を集中的に取り扱うようになっている。
【００１２】
また、放射性薬剤検定室１１は、ホットラボ１０で合成した放射性薬剤の検定を行う部屋であり、該検定室１１は、ホットラボ１０に隣接して設置されている。
【００１３】
サイクロトロン室１３には、放射性薬剤の原料になる放射性核種を原子核変換により製造するサイクロトロン２３が設置されている。なお、サイクロトロン室１３を取り囲むのは放射線を遮蔽するための壁である。サイクロトロン２３は重量があるので、建物の１階や地階等、床のしっかりとした場所に設置される。
【００１４】
医療従事者用階段２７は、ホットラボ１０の出入口の斜め向かいに設置され、ホットラボ１０からの利用が容易になっている。ちなみに、ホットラボ１０の出入口及び従業者用階段２７は、ＰＥＴ施設Ａの中央部に配置され、２階の操作室・読影室１への行き来を容易にしている。
【００１５】
また、ＰＥＴ施設Ａの１階は、図１を基準にして右下略１／４の部分に非管理区域が設けられている。この非管理区域には、入口８１、１階受付８２Ａ、階段８５、同エレベータ８６、管理室、医療従事者用の更衣室、同トイレが配置されている。
【００１６】
〔２階のレイアウト〕
図２に示すように、ＰＥＴ施設Ａの上層階（以後２階として説明する）は、一部を除いて管理区域になっている。この管理区域は、中央部が医療従事者のためのスペース（医療従事者滞在スペース）に、外周部が被検者のためのスペース（被検者滞在スペース）になっており、医療従事者の作業効率を重視すると共に、両者の動線が交錯しないようになっている。
【００１７】
また、医療従事者のためのスペースは、医療従事者が常時滞在する操作室・読影室１を取り囲むように、ペットカメラ室２（計３室）、廃棄物保管庫１６、処置室６、医療従事者用階段２７、血液検査室１２が、医療従事者用の出入口を操作室・読影室１に向けて配置されている。つまり、操作室・読影室１に隣接・近接して、各部屋２，６，１２，１６や階段２７が配置されている。この構成により、医療従事者が常時滞在する操作室・読影室１から医療業務を行う各部屋２，６，１２，１６や医療従事者用階段２７への移動距離を短くすることができる。つまり、医療従事者の動線を短くすることができる。
【００１８】
なお、操作室・読影室１は、医療従事者が、ＰＥＴカメラ２１の操作、ＰＥＴカメラ２１で撮影した画像の読影等を行う部屋であり、コンソール２２が備えられている。この操作室・読影室１には、前記したとおり医療従事者が常時滞在している。
【００１９】
ＰＥＴカメラ室２には、それぞれＰＥＴカメラ２１が備えられている。このＰＥＴカメラ室２は、操作室・読影室１の側と被検者用通路３（３ｂ）の側に出入口が設けられており、医療従事者と被検者の動線が交錯しないようになっている。
【００２０】
処置室６は、被検者に放射性核種を含む放射性薬剤を投与（経口投与・経気道投与・皮下投与）する部屋であり、ＰＥＴカメラ室２と同様に、操作室・読影室１の側と被検者用通路３（３ａ）の側に出入口が設けられており、医療従事者と被検者の動線が交錯しないようになっている。
【００２１】
血液検査室１２は、医療従事者が処置室６等で被検者からサンプリングした血液を検査する部屋であり、操作室・読影室１の側に出入口が設けられている。また、廃棄物保管室１６は、廃棄物を保管しておく部屋であり、操作室・読影室１の側に出入口が設けてある。なお、血液検査室１２、廃棄物保管室１６とも、医療従事者のみが立ち入るようになっている。
【００２２】
また、医療従事者用階段２７は、ＰＥＴ施設の１階の管理区域と２階の管理区域を繋ぎ、１階のホットラボ１０との往来に使用される。
【００２３】
一方、外周の被検者のためのスペースには、安静室４、被検者用トイレ７、回復室５、汚染検査室９と、これらを結ぶ被検者用通路３（３ａ，３ｂ，３ｃ）が配置されている。
【００２４】
安静室４は、処置室６で放射性薬剤を投与された被検者が安静にする場所であり、図示しないベッド等が備えられている。また、回復室５は、検査後（ＰＥＴカメラ室２で撮影をした後）、被検者に投与された放射性薬剤に含まれる放射性核種の減衰を待つための部屋であり、図示しないソファ等が備えられている。
【００２５】
被検者用トイレ７は、安静室４で安静にしていた被検者が検査前に排尿をするためのトイレである。
【００２６】
なお、ＰＥＴカメラ室２、処置室６は、医療従事者と被検者とが同じ部屋に立ち入る場所であるが、前記したとおり、被検者用、医療従事者用にそれぞれ出入口が設けてあり、被検者と医療従事者の動線が交錯しないようになっている。
【００２７】
被検者用通路３ａは、問診待合室８３と安静室４とを繋ぐ通路である。被検者用通路３ｂ，３ｃは、安静室４と回復室５を繋ぐ通路である。
【００２８】
図２に示すように、ＰＥＴ施設Ａの２階には、管理区域のほかに非管理区域が設けられている。非管理区域は、２階受付８２Ｂ、問診待合室８３、問診室８４、階段８５、エレベータ８６、被検者用更衣室８が配置されている。
【００２９】
このうち、問診室８４は、医師（医療従事者）が被検者に問診を行う部屋であり、処置室６（操作室・読影室１）の側と問診待合室３の側に出入口が設けられており、医療従事者と被検者の動線が交錯しないようになっている。なお、操作室・読影室１と問診室８４の行き来は、処置室６を経由する。
【００３０】
つまり、第１実施形態のＰＥＴ施設Ａは、放射線の管理区域における被検者の動線と医療従事者の動線を分離し、かつ医療従事者の動線を管理区域（或いはＰＥＴ施設Ａ）の内側に配置した構成をしている。或いは、処置室６と複数のＰＥＴカメラ室２を操作室・読影室１に隣接させ、その周囲に被験者用通路３を設置した構成をしている。或いは、被検者の動線と医療従者の動線を分離し、かつ、複数のＰＥＴカメラ室２のそれぞれの出入口、処置室６の出入口を、医療従事者が滞在するスペースである操作室・読影室１に面するように配置して、これら出入口を医療従事者が利用するようにした構成をしている。この構成のＰＥＴ施設Ａは、医療従事者の観点からすれば、動線の短縮化及び被検者との動線の分離が図られ、これにより、医療従事者が効率的にしかも被検者から受ける被曝線量を低減して活動できるようにした構造（レイアウト）をしているといえる。換言すると、医療従事者の被曝線量を低減しつつ、医療従事者の動線を短縮化し、ＰＥＴ施設の運用効率の向上を図ることのできる構造をしているといえる。
【００３１】
次に、この第１実施形態のＰＥＴ施設Ａの動作を図１及び図２を参照して説明する。
被検者は、１階の入口８１からＰＥＴ施設Ａに入り、受付８２Ａで受付をして階段８５又はエレベータ８６で２階に向かう。２階の非管理区域に上がってきた被検者は、２階の受付８２Ｂにて登録をした後に問診待合室８３にて問診を待つ。問診室８４にて医師（医療従事者）による問診を受けた被検者は、被検者用更衣室８にて検査着に着替える（着替えを行わない場合もある）。ちなみに被検者用更衣室８は、管理区域内に配置するようにしても、非管理区域内に配置するようにしてもよい。
【００３２】
着替えた被検者は管理区域内に入り、処置室６にて放射性核種を含む放射性薬剤を投与された後、被検者用通路３ａを通り、安静室４に移動する。そして、放射性薬剤の体内分布の定常化を図るため、この安静室４にて５０分程度待機する。被検者は、安静待機後、撮影前に安静室４の手前側に配置された被検者用トイレ７にて排尿し、被検者用通路３ｂを通りＰＥＴカメラ室２に移動して検査を受ける。具体的には、被検者は、３つあるＰＥＴカメラ室２（ＰＥＴカメラ２１）のうち、予め定められたいずれか１つのＰＥＴカメラ室２で写真を撮影される。
【００３３】
撮影後、被検者は被検者用通路３ｃを通り、回復室５に移動する。そして、投与された放射性核種の減衰を待つため、この回復室５にて６０分程度待機する。なお、回復室５における待機を行わない場合もある。
【００３４】
被検者は、回復室５で待機した後、汚染検査室９を通って管理区域から退出する。着替えは、非管理区域にある被検者用更衣室８にて行う。以上が被検者の動線である。
【００３５】
一方、医療従事者は、問診室８４で被検者の問診を行う場合は、操作室・読影室１から処置室６を経由して非管理区域の問診室８４に行くことができる。また、処置室６で被検者の処置を行う場合は、操作室・読影室１から直接処置室６に行くことができる。ＰＥＴカメラ室２、血液検査室１２、廃棄物保管室１６についても、操作室・読影室から直接行くことができる。図２から理解されるように、医療従事者が常時滞在する操作室・読影室１を中心に、各部屋２，６，１２，１６，８４（その出入口）を配置（スター型）しているので、どの部屋２，６…に行くにも円滑な動線が確保される。
【００３６】
なお、１階のホットラボ１０へ行く場合は、医療従事者用階段２７の出入口が操作室・読影室１に面しているので、該操作室・読影室１から容易にホットラボ１０へ行くことができる。また、その逆もいえ、ホットラボ１０から操作室・読影室１に容易に行くことができる。また、処置室６は医療従事者用階段２７（その出入口）に隣接しているので、ホットラボ１０から処置室６に行くのも容易である。
【００３７】
この第１実施形態のＰＥＴ施設Ａによれば、放射線の管理区域内の各部屋２，６…が、医療従事者が常時滞在する操作室・読影室１を中心にスター型に配置されているので、換言すると操作室・読影室１に各部屋２，６…の出入口が面して設けられているので、毎日作業を行う医療従事者の動線を短縮化して医療従事者の作業効率を向上することができる。
【００３８】
一方、被検者は、時計回りに進んでいくことによりＰＥＴ検診を受けることができる。また、安静室４と回復室５をＰＥＴ施設Ａの対角線の位置に配置しているので、検診待ちの被検者と検診後の被検者による相互の被曝を低減することができる。
【００３９】
また、図２から明らかなように医療従事者と被検者との動線を明確に分離しているので、医療従事者が被検者から被曝することも少なくなる。また、被検者がＰＥＴ施設Ａ内で迷子になることも少なくなる。
【００４０】
なお、ホットラボ１０には、真上の２階に位置する処置室６に繋がる放射性薬剤運搬用エレベータを設けるようにしてもよい。
【００４１】
≪第２実施形態≫
次に、第２実施形態のＰＥＴ施設を説明する。
図３は、第２実施形態のＰＥＴ施設を示す図であり、処置室とホットラボとが隣接して配置されていない場合の放射性薬剤の搬送構造を例示する。なお、第１実施形態と共通する部分については、同じ符号を付してその説明を省略することとする。
【００４２】
第２実施形態のＰＥＴ施設Ｂでは、図３に示すように、処置室６とホットラボ１０とが隣接して配置されていない。このため、処置室６とホットラボ１０とを放射性薬剤搬送装置３１で直結し、必要に応じて処置室６とホットラボ１０内に昇降機３２を設置する。ホットラボ１０においてシリンジに分注された放射性薬剤は遮蔽容器３３に入れられて、昇降機３２により、通路を人が通行するのに支障のない高さに設置された放射性薬剤搬送装置３１に上げられる。放射性薬剤搬送装置３１により処置室６に運ばれた遮蔽容器は昇降機により医療従事者の利便性を考慮した高さまで降ろされる。このような搬送装置を設置することにより、医療従事者が直接運搬するよりも、医療従事者の負担を軽減し、かつ、被曝線量を低減することが可能となる。もちろん、被検者及び医療従事者双方の円滑な動線の確保にも活用でき、もって医療従事者の被検者からの被曝線量の低減に資することができる。
【００４３】
なお、この放射性薬剤の搬送構造は、処置室６が２階に配置され、ホットラボ１０が１階に配置される第１実施形態のＰＥＴ施設Ａ（図１、図２参照）にも、何等支障なく適用することができ、１階のホットラボ１０で分注された放射性薬剤を人手によらずに２階の処置室６に搬送することができる。また、処置室６とホットラボ１０とが別々の建屋内に配置されている場合にも、本実施形態の搬送構造を適用することができる。
【００４４】
≪第３実施形態≫
次に、第３実施形態のＰＥＴ施設を説明する。
図４は、第３実施形態のＰＥＴ施設を示す図であり、処置室における医療従事者の被曝低減構造を例示する。なお、第１実施形態等と共通する部分については、同じ符号を付してその説明を省略することとする。
【００４５】
第３実施形態のＰＥＴ施設Ｃでは、線源の位置、強度に応じ、図４に示すように、医療従事者の滞在場所３５の周囲にコ字型の鉛や鉛ガラス等からなるガンマ線遮蔽衝立３４が設置してある。
【００４６】
ＰＥＴ施設Ｃの処置室６では、被検者に放射性薬剤を投与する。このため、処置室６では、放射性薬剤を投与された被検者及び放射性薬剤が医療従事者の近傍に存在する。このような状況の下で局所的な線源からの被曝を低減するためには、線源の方向を考慮に入れて、適切な形状の遮蔽衝立を設置する被曝低減構造（被曝低減方法）が有効である。放射性薬剤の自動注入装置等を使用しながら医療従事者が被検者を観察する必要がある場合には被検者の位置３６の方向を鉛ガラス等としたガンマ線遮蔽衝立を設置する。このように、遮蔽衝立を設置することにより、建屋全体の壁厚を厚くすることなく、局所的な線源による医療従事者の被曝を低減することが可能となる。なお、ガンマ線遮蔽衝立３４は、平板型、Ｌ型等でもよい。
【００４７】
≪第４実施形態≫
次に、第４実施形態のＰＥＴ施設を説明する。
図５は、第４実施形態のＰＥＴ施設を示す図であり、モニタカメラ、スピーカ等を設置し、被検者を誘導する構成を例示する。なお、第１実施形態等と共通する部分については、同じ符号を付してその説明を省略することとする。
【００４８】
第４実施形態では、図５に示すように、ＰＥＴ施設Ｄの被検者用通路３、安静室４、回復室５にそれぞれモニタカメラ４１及びスピーカ４２を設置し、操作室・読影室１にモニタカメラ４１の画像を表示する画面４３及び放送設備４４を設置している。モニタカメラ４１、スピーカ４２、画面４３、放送設備４４は、周知のものを適用することができる。
【００４９】
この第４実施形態のＰＥＴ施設Ｄによれば、例えば第１実施形態のＰＥＴ施設Ａ（図１、図２参照）で得られる効果のほか、被検者に接近することなく被検者を誘導することが可能となり、医療従事者の放射性薬剤投与後の被検者から受ける被曝線量を低減することができる。また、被検者が通常立ち入るべきでない場所に立ち入ろうとした際にこれを監視して、適切に誘導することができる。そして、医療従事者の不慮の被曝を避けることが可能となる。なお、画面４３や放送設備４４は、ＲＩ管理室（従事者控室）、受付、問診室８４等に設置することもできる。
【００５０】
≪第５実施形態≫
次に、第５実施形態のＰＥＴ施設を説明する。
図６は、第５実施形態のＰＥＴ施設を示す図であり、被検者の動線を床、天井等に表示し、安静室のベッド、ＰＥＴカメラ室、回復室のソファに番号を表示して被検者を誘導する構成を例示する。なお、第１実施形態等と共通する部分については、同じ符号を付してその説明を省略することとする。
【００５１】
第５実施形態では、図６に示すように、ＰＥＴ施設Ｅには被検者の動線を案内する表示（被検者動線）が表示してある。この被検者動線は、床や壁に矢印を付したラインを書き込んだり、テープを貼り付けたりすることで表示することができる。また、被検者動線は、天井や壁に案内の看板を設けることで表示することができる。また、ＰＥＴ室２の入口、安静室４のベッド、回復室５のソファには、ＰＥＴカメラ室２の数に対応して、丸数字で１〜３番までの番号（識別表示；安静室ベッド番号、ＰＥＴカメラ室番号、回復室ソファ番号）、が付してある。この被検者動線や番号の意味内容等は、例えば受付８２Ｂや問診室８４で知らされるようになっている。
【００５２】
この第５実施形態の場合、ＰＥＴ施設Ｅの２階の非管理区域にある問診室８４で医師の問診を受けた被験者は、被検者動線の表示に従って管理区域に入域し、処置室６で放射性薬剤の投与等の処置を受ける。この際、被検者は必要に応じて被検者用更衣室８で着替えを行う。処置室６で放射性薬剤を投与された被検者は、被検者動線の表示に従って安静室４に入り、予め指示された安静室ベッド番号（例えば丸１）が表示されたベッドで安静にして待機する。検査（撮影）の時間になると、表示された被検者動線に従って安静室４に隣接する被検者用トイレ７で放尿を行い、次いで指示されたＰＥＴカメラ室番号（同じ番号の丸１）が表示されたＰＥＴカメラ室２に入って、ＰＥＴカメラ２１による検査を受ける。検査終了後は、表示された被検者動線に従って回復室５に入り、指示された回復室ソファ番号（同じ番号の丸１）が表示されたソファでしばらくの間投与された放射性薬剤に含まれる核種の崩壊が進行して放射線の強度が減衰するのを待つ（待機する）。回復室５で所定時間待機した後は、表示された被検者動線に従って管理区域から退出する。この際、被検者用更衣室８での着替え、汚染検査室９での検査を必要に応じて行う。管理区域から退出した被検者は、エレベータ８６で１階に向かい、受付８２（図５参照）を通ってＰＥＴ施設Ｅをでる。
【００５３】
この第５実施形態のＰＥＴ施設Ｅによれば、例えば第１実施形態のＰＥＴ施設Ａ（図２参照）で得られる効果のほか、被検者が迷わずに検査を受けることができるようになるという効果も得られる。また、このような被検者用動線や安静室ベッド番号等は、被検者が直感的に理解できるものであるので、医療従事者の被検者に対する検査手順の説明を省力化することができる。また、放射性薬剤投与後の被検者に接近することなく被検者を確実に誘導することが可能となり、医療従事者の被検者から受ける被曝線量を低減することができる。また、被検者が通常立ち入るべきでない場所に誤って立ち入るような事態を防止することができる。
【００５４】
≪参考例≫
次に、参考例を説明する。
なお、ここで説明する参考例は、医療従事者の動線を短縮化する第１〜第５実施形態とは異なり、被検者の動線を短縮化するものである。
【００５５】
図７及び図８は、参考例のＰＥＴ施設を示す図であり、このうち、図７はサイクロトロン等重量物が配置される下層階の平面図、図８はＰＥＴカメラが設置される上層階の平面図である。なお、第１実施形態と共通する部分については、同じ符号を付してその説明を省略することとする。
【００５６】
図７に示すように、参考例のＰＥＴ施設Ｆの下層階（以後１階として説明する）の管理区域には、ホットラボ１０、放射性薬剤検定室１１、サイクロトロン室１３等が配置された構成をしている。ホットラボ１０には、真上の２階に位置する処置室６に繋がる放射性薬剤運搬用エレベータ２４が備えられている。また、ホットラボの出入口の向かいには、１階と２階を繋ぐ医療従事者用階段２７が位置しており、２階へのアクセスが容易になっている。また、サイクロトロン室１３には、重量物であるサイクロトロン２３が備えられている。
【００５７】
そして、１階の非管理区域には、入口８１、受付８２、１階と２階を繋ぐ階段８５、１階と２階を繋ぐエレベータ８６等が配置された構成をしている。
【００５８】
一方、２階には、図８を基準にして、左手に非管理区域が、中央から右手に管理区域が配置されている。２階の左右方向の中央部分には被検者用通路３、安静室４、回復室５を兼ねた待機スペース３０が配置されている。また、待機スペース３０の右隣には、ＰＥＴカメラ２１をそれぞれ１台ずつ備えたＰＥＴカメラ室２が縦に（奥から手前にかけて）３部屋並んで（隣接して）配置されている。また、３つ縦に並んだカメラ室２の右隣には縦長の操作室・読影室１が配置されている。また、待機スペース３０の奥には処置室６が、その左隣には、通路を挟んで放射性薬剤検査室１２が配置されている。さらに、待機スペース３０の手前には被検者用トイレ７が配置されている。この被検者用トイレ７は、待機スペース３０及びＰＥＴカメラ室２に隣接して設置されたトイレに該当し、被検者の動線が円滑になると共に、被検者の動線が短縮化される。
【００５９】
また、２階には、操作室・読影室１の奥から医療従事者用階段２７に繋がる左右方向の通路、即ち医療従事者用通路９１が配置されている。この医療従事者用通路９１は、奥側のＰＥＴカメラ室２、処置室６、放射性薬剤検査室１２に隣接して配置され、操作室・読影室１から処置室６、放射性薬剤検定室１２、１階のホットラボ１０へのアクセス通路等としての役割を有する。
【００６０】
ちなみに、図８に示されるように、各カメラ室２には、操作室・読影室１の側に医療従事者用の出入口が、被検者用通路３等を兼ねるスペース３０の側に被検者用の出入口がそれぞれ設けられて、各カメラ室２へのアクセスを容易にすると共に、被検者と医療従事者との動線の交錯を防止している。
【００６１】
処置室６についても同様であり、処置室６には、医療従事者用通路９１の側に医療従事者用の出入口が、被検者用通路３等を兼ねるスペース３０の側に被検者用の出入口が設けられて、処置室６へのアクセスを容易にすると共に、被検者と医療従事者との動線の交錯を防止している。また、処置室６には、既に説明した放射性薬剤運搬用エレベータ２４が備えられており、１階にあるホットラボ１０から放射性薬剤を、人手による運搬によらずとも得ることができるようになっている。
【００６２】
また、２階の非管理区域には、受付８２Ｂ、問診待合室８３、問診室８４、１階と２階を繋ぐ階段８５、同エレベータ８６、被検者用更衣室８等が配置されている。
【００６３】
なお、参考例のＰＥＴ施設Ｆは、被検者の動線と医療従事者の動線を分離し、処置室６、複数のＰＥＴカメラ室２、被検者用トイレ７を、放射性薬剤投与後の被検者が滞在する待機スペース（被検者滞在スペース）３０に隣接して配置した構成をしているといえる。また、放射線の管理区域に終える被検者の動線と医療従事者の動線を分離すると共に、複数のＰＥＴカメラ室２の出入口、処置室６の出入口、被検者用トイレ７の出入口を、被検者の待機スペース（滞在スペース）３０に面して配置した構成をしているといえる。さらに、医療従事者が常時滞在する操作・読影室（医療従事者滞在スペース）１を、前記処置室６及び複数のＰＥＴカメラ室２を挟むように、待機スペース３０の反対側に配置した構成をしているといえる。この点、複数のＰＥＴカメラ室２のそれぞれの出入口、処置室６の出入口を、医療従事者が滞在するスペース（操作室・読影室１）に面するように配置した、第１実施形態〜第５実施形態のＰＥＴ施設とは異なる。
【００６４】
次に、以上説明した参考例のＰＥＴ施設Ｆの動作を説明する（図７、図８参照）。
被検者は、１階の入口８１からＰＥＴ施設Ｆに入り、受付８２Ａで受付をして階段８５又はエレベータ８６で２階に向かう。２階の非管理区域に上がってきた被検者は、２階の受付８２Ｂにて登録をした後に問診待合室８３にて問診を待つ。問診室８４にて医師による問診を受けた被検者は、被検者用更衣室８にて検査着に着替える（着替えを行わない場合もある）。
【００６５】
着替えた被検者は管理区域内に入り、処置室６にて放射性核種を含む放射性薬剤を投与された後、被検者用通路、３安静室４、回復室５を兼ねる待機スペース３０に移動する。そして、放射性薬剤の体内分布の定常化を図るため、この待機スペース３０にて５０分程度待機する。被検者は、待機スペース３０の手前側に配置された被検者用トイレ７にて排尿し、被検者用通路３を通りＰＥＴカメラ室２に移動して検査を受ける。具体的には、被検者は、３つあるＰＥＴカメラ室２（ＰＥＴカメラ２１）のうち、予め定められたいずれか１つのＰＥＴカメラ室２で写真を撮影される。
【００６６】
撮影後、被検者は待機スペース３０に戻り、投与された放射性核種の減衰を待つため、この回復室５にて６０分程度待機する。なお、回復室５における待機を行わない場合もある。
【００６７】
被検者は、待機スペース３０で待機した後、汚染検査室９を通って管理区域から退出する。着替えは、必要に応じて非管理区域にある被検者用更衣室８にて行う。以上が被検者の動線である。
【００６８】
この構成によれば、待機スペース３０に、各ＰＥＴカメラ室２の出入口、処置室６の出入口、被検者用トイレ７の出入口等が面しているので、被検者の動線の明確化及び短縮化を達成することができる。併せて、被検者と医療従事者の動線を確実に分離することができる。なお、被検者の動線を明確化及び短縮化することで、医療従事者の被検者に対する動線の説明（ガイダンス）が容易になり、医療従事者の作業負担が軽減される。また、医療従事者と被検者との接触を短時間に済ませることも可能になる。また、被検者の動線が短くなる分、被検者に与える肉体的な負担が少なくなる。
【００６９】
一方、図８から容易に理解されるように、医療従事者は被検者の介護等の非定常作業を除いて、待機スペース３０に立ち入ることなく、医師による問診、放射性薬剤投与、放射線技師によるＰＥＴカメラ撮影を実施することができる。即ち、上記のレイアウトにすることにより、第１実施形態と同様に、被検者の動線と医療従事者の動線の交錯を防止して、医療従事者の被曝線量を低減すること等が可能となる。
【００７０】
なお、２階の管理区域にいる医療従事者が１階の管理区域に用事があるときは、医療従事者用通路９１、医療従事者用階段２７を通って１階の管理区域に行くことができる。この際、被検者の動線と交錯することがない。ちなみに、１階に降りると直ぐ目の前にホットラボ１０の出入り口があるので２階からホットラボ１０へのアクセスが容易である。また、その逆もいえ、ホットラボ１０から２階へのアクセスも容易である。
【００７１】
ちなみに、参考例では、放射性薬剤運搬用エレベータ２４を設けてホットラボ１０における合成器、分注器により生成・分注された放射性薬剤を２階の処置室６に搬送することにより、放射性薬剤の動線を最短化している。即ち、シリンジに分注された放射性薬剤は遮蔽容器に入れられて、放射性薬剤運搬用エレベータ２４により処置室６に運搬され、使用後のシリンジは放射性薬剤運搬用エレベータ２４によりホットラボ１０に戻されて、廃棄物保管室１７にて保管される。このように、放射性薬剤の動線を最短化することにより、医療従事者の被曝を低減することができる。
【００７２】
また、ホットラボ１０が１階（下層階）に配置されているので、放射性薬剤を投与された被検者によるホットラボ１０の医療従事者の被曝線量を低減することができる。
【００７３】
つまり、参考例によれば、被検者と医療従事者との動線を分離する課題（医療従事者が被検者から受ける被曝線量の低減化、被検者を案内・誘導する作業の省力化等の課題）、被検者の動線を短縮化して被検者の負担を軽減する課題等が解決される。
【００７４】
なお、以上説明した本発明は、前記した実施形態に限定されることなく幅広く変形実施することができる。例えば、各実施形態を適宜組み合わせて実施するようにしてもよい。また、サイクロトロン等の重量物を設置するのは、ＰＥＴ施設の地階でも１階でも、或いは２階でもよく、特に階を限定するものではない。また、ホットラボを上層階に、安静室や回復室を下層階に配置する構成としてもよい。また、全体を１つの階に纏めて配置する構成としてもよい。また、安静室に備えられるベッドの間や回復室に備えられるソファの間にガンマ線遮蔽衝立を置くようにして、被検者が他の被検者から受ける放射線の量を少なくするようにしてもよい。また、ＰＥＴ施設とは、既に記載したように、エミッションＣＴ、即ちＳＰＥＣＴやＰＥＴ等を運用する医療施設であり、ＰＥＴ施設に限定されるものではない。また、ＰＥＴカメラもＳＰＥＣＴ等のエミッションＣＴ用のカメラを含むものである。
【００７５】
また、被検者用更衣室８（図等参照）を非管理区域に配置することとしたが、管理区域に配置するようにしてもよい。また、問診待合室８３、問診室８４も管理区域に配置するようにしてもよい。
【００７６】
【発明の効果】
以上説明した本発明により、医療従事者の被曝量を低減しつつ、医療従事者の動線を短縮化し、ＰＥＴ施設の運用効率の向上を図ること等ができる。

BACKGROUND OF THE INVENTION
The present invention relates to a layout of a medical facility (hereinafter referred to as “PET facility”) that operates emission CT, that is, SPECT (Single Photon Emission Computed Tomography), PET (Positron Emission Tomography), and the like.
[0002]
[Prior art]
By using radionuclide as a tracer and tomographic imaging of its distribution in the body, the probability of early detection of cancer is greatly increased by PET screening, which can observe the metabolic function of body cells and metabolic function tests. Make a cancer diagnosis ¹⁸ Insurance is also applied to F-FDG (Fluoro Deoxy Glucose) tests, and the demand for PET screening is expected to increase dramatically in the future. As the demand for PET screening increases, it is important to reduce the exposure dose of medical workers (doctors, radiologists, nurses, etc.).
[0003]
In PET screening, after administering a radiopharmaceutical to a subject in the treatment room, waiting for about 50 minutes in a rest room to stabilize the distribution of the radiopharmaceutical, and then urinating in the toilet, with a PET camera Move to the shooting room and take a picture. In some cases, in order to wait for the decay of the administered radionuclide, the examination is completed after waiting in the recovery room for about 60 minutes. Unlike other radiation facilities, the subject to be a source moves greatly within the radiation control area. The dose rate on the body surface of the subject immediately after administration of the radiopharmaceutical is approximately several hundred μSv / h. When a health care worker stays in the vicinity of a subject for a long time, the dose may exceed the annual dose limit (maximum 50 mSv per year) stipulated in the Radiation Hazard Prevention Law.
Therefore, in order to reduce the radiation dose of the medical staff, it is necessary to avoid the approach between the subject and the medical staff, and to separate the flow line of the subject and the medical staff (for example, non- Patent Document 1).

The recovery room 5 is a room for waiting for the decay of the radionuclide contained in the radiopharmaceutical administered to the subject after the examination (after photographing in the PET camera room 2). Is provided.
[0025]
The subject toilet 7 is a toilet for the subject who has been rested in the rest room 4 to urinate before the examination.
[0026]
The PET camera room 2 and the treatment room 6 are places where the medical staff and the subject enter the same room, but as described above, entrances and exits are provided for the subject and the medical staff, respectively. The flow lines of the subject and the medical staff are not intermingled.
[0027]
The subject passage 3 a is a passage connecting the inquiry waiting room 83 and the rest room 4. The patient passages 3 b and 3 c are passages connecting the rest room 4 and the recovery room 5.
[0028]
As shown in FIG. 2, a non-managed area is provided on the second floor of the PET facility A in addition to the managed area. In the non-management area, the second floor reception 82B, the inquiry waiting room 83, the inquiry room 84, the stairs 85, the elevator 86, and the changing room 8 for the subject are arranged.
[0029]
Of these, the interview room 84 is a room where a doctor (medical worker) interviews the subject, and entrances are provided on the treatment room 6 (operation room / reading room 1) side and the interview waiting room 3 side. The flow lines of medical personnel and subjects are not intermingled. The operation room / interpretation room 1 and the interrogation room 84 go through the treatment room 6.
[0030]
That is, the PET facility A of the first embodiment separates the subject's flow line and the medical worker's flow line in the radiation management area, and the medical worker's flow line in the management area (or PET facility A). It has a configuration arranged inside. Alternatively, the treatment room 6 and the plurality of PET camera rooms 2 are adjacent to the operation room / interpretation room 1, and the subject passage 3 is installed around the treatment room 6 and the interpretation room 1.

It arrange | positions so that the reading room 1 may be faced, and it has the structure which a medical worker utilized these entrances. In the PET facility A having this configuration, from the viewpoint of a medical worker, the flow line can be shortened and the flow line can be separated from the subject. It can be said that it has a structure (layout) that enables it to work with reducing the exposure dose received from the plant. In other words, it can be said that it has a structure that can reduce the radiation dose of the medical staff, shorten the flow line of the medical staff, and improve the operation efficiency of the PET facility.
[0031]
Next, the operation of the PET facility A according to the first embodiment will be described with reference to FIGS.
The subject enters the PET facility A from the entrance 81 on the first floor, receives at the reception 82A, and goes to the second floor through the stairs 85 or the elevator 86. The subject who has entered the unmanaged area on the second floor waits for an inquiry in the interview waiting room 83 after registering at the reception 82B on the second floor. A subject who has received an inquiry by a doctor (medical worker) in the interview room 84 changes into a check-up in the changing room 8 for the subject (there may not be a change of clothes). Incidentally, the changing room 8 for the subject may be arranged in the management area or in the non-management area.
[0032]
The changed subject enters the management area, is administered a radiopharmaceutical containing a radionuclide in the treatment room 6, and then moves to the rest room 4 through the subject passage 3a. Then, in order to stabilize the distribution of the radiopharmaceutical in the body, it waits for about 50 minutes in the rest room 4. The subject urinates in the toilet 7 for the subject placed on the front side of the rest room 4 before taking a picture after waiting for a rest, moves to the PET camera room 2 through the passage 3b for the subject, and is examined. Receive. Specifically, the subject takes a picture in one of the three PET camera rooms 2 (PET camera 21), which is determined in advance.
[0033]
After imaging, the subject moves to the recovery room 5 through the subject passage 3c. And in order to wait for attenuation of the administered radionuclide, it waits for about 60 minutes in this recovery room 5. In some cases, no waiting is performed in the recovery chamber 5.
[0034]
The subject waits in the recovery room 5 and then leaves the management area through the contamination inspection room 9. Changing clothes is performed in the changing room 8 for the subject in the unmanaged area. The above is the flow line of the subject.
[0035]
On the other hand, the medical staff can go to the interrogation room 84 in the unmanaged area from the operation room / interpretation room 1 via the treatment room 6 when conducting an interrogation of the subject in the interrogation room 84. Further, when the subject is to be treated in the treatment room 6, it is possible to go directly from the operation room / interpretation room 1 to the treatment room 6. The PET camera room 2, blood test room 12, and waste storage room 16 can also be accessed directly from the operation room / interpretation room. As can be understood from FIG. 2, the rooms 2, 6, 12, 16, 84 (entrances and entrances) are arranged (star type) around the operation room / interpretation room 1 where medical staff always stay. Therefore, a smooth flow line is ensured even if it goes to any room 2,6 ....
[0036]
When going to the hot lab 10 on the first floor, the entrance / exit of the stairs 27 for medical staff faces the operation room / interpretation room 1, so that it is easy to go to the hot lab 10 from the operation room / interpretation room 1. it can. Further, conversely, the hot lab 10 can easily go to the operation room / interpretation room 1. Moreover, since the treatment room 6 is adjacent to the medical staff stairs 27 (entrance / exit thereof), it is easy to go to the treatment room 6 from the hot lab 10.
[0037]
According to the PET facility A of the first embodiment, the rooms 2, 6... In the radiation management area are arranged in a star shape centering on the operation room / reading room 1 where medical staff always stay. Therefore, in other words, the operation room / interpretation room 1 is provided with the entrances and exits of the respective rooms 2, 6..., Thereby shortening the flow of the medical staff who perform daily work and improving the work efficiency of the medical staff. Can be improved.
[0038]
On the other hand, the subject can receive a PET examination by proceeding clockwise. In addition, since the rest room 4 and the recovery room 5 are arranged at diagonal positions in the PET facility A, mutual exposure between the subject waiting for the examination and the subject after the examination can be reduced.
[0039]
Further, as apparent from FIG. 2, the flow line between the medical staff and the subject is clearly separated, so that the medical staff is less likely to be exposed from the subject. In addition, the subject is less likely to get lost in the PET facility A.
[0040]
The hot lab 10 may be provided with a radiopharmaceutical transport elevator connected to the treatment room 6 located on the second floor directly above.
[0041]
<< Second Embodiment >>
Next, the PET facility of the second embodiment will be described.
FIG. 3 is a diagram showing a PET facility according to the second embodiment, and illustrates a radiopharmaceutical transport structure when a treatment room and a hot lab are not arranged adjacent to each other. In addition, about the part which is common in 1st Embodiment, suppose that the same code | symbol is attached | subjected and the description is abbreviate | omitted.
[0042]
In the PET facility B of the second embodiment, as shown in FIG. 3, the treatment room 6 and the hot lab 10 are not arranged adjacent to each other. For this reason, the treatment room 6 and the hot lab 10 are directly connected by the radiopharmaceutical transfer device 31, and the elevator 32 is installed in the treatment room 6 and the hot lab 10 as necessary. The radiopharmaceutical dispensed into the syringe in the hot lab 10 is placed in the shielding container 33 and is raised by the elevator 32 to the radiopharmaceutical transport device 31 installed at a height that does not hinder a person to pass through the passage. The shielded container carried to the treatment room 6 by the radiopharmaceutical transporting device 31 is lowered to a height considering the convenience of the medical staff by the elevator. By installing such a transfer device, it is possible to reduce the burden on the medical worker and reduce the exposure dose, compared to the case where the medical worker directly transports. Of course, it can also be used to ensure smooth flow lines for both the subject and the medical staff, thereby contributing to a reduction in exposure dose from the medical staff.
[0043]
Note that this radiopharmaceutical transport structure has no problem in the PET facility A (see FIGS. 1 and 2) of the first embodiment in which the treatment room 6 is arranged on the second floor and the hot lab 10 is arranged on the first floor. The radiopharmaceutical dispensed in the hot lab 10 on the first floor can be transported to the treatment room 6 on the second floor without human hands. Moreover, also when the treatment room 6 and the hot laboratory 10 are arrange | positioned in a separate building, the conveyance structure of this embodiment is applicable.
[0044]

In the treatment room 6 of the PET facility C, a radiopharmaceutical is administered to the subject. For this reason, in the treatment room 6, the subject to whom the radiopharmaceutical is administered and the radiopharmaceutical are present in the vicinity of the medical staff. Under these circumstances, in order to reduce exposure from local radiation sources, an exposure reduction structure (exposure reduction method) in which a shielding screen with an appropriate shape is installed in consideration of the direction of the radiation source. It is valid. When a medical worker needs to observe a subject while using an automatic injection device for a radiopharmaceutical or the like, a gamma-ray shielding screen having lead glass or the like in the direction of the position 36 of the subject is installed. Thus, by installing the shielding screen, it is possible to reduce the exposure of the medical staff by the local radiation source without increasing the wall thickness of the entire building. The gamma ray shielding screen 34 may be a flat plate type, an L type, or the like.
[0047]
<< Fourth Embodiment >>
Next, the PET facility according to the fourth embodiment will be described.
FIG. 5 is a diagram illustrating a PET facility according to the fourth embodiment, and illustrates a configuration in which a monitor camera, a speaker, and the like are installed to guide a subject.

A waiting space 30 serving as a subject passage 3, a rest room 4, and a recovery room 5 is disposed in the central portion of the second floor in the left-right direction. Further, on the right side of the standby space 30, three PET camera rooms 2 each having one PET camera 21 are arranged vertically (from the back to the front) side by side (adjacent). In addition, a vertically long operation room / reading room 1 is arranged to the right of the three camera rooms 2 arranged vertically. Further, the treatment room 6 is disposed in the back of the standby space 30, and the radiopharmaceutical examination room 12 is disposed on the left side of the waiting space 30 with a passage therebetween. Further, a subject toilet 7 is disposed in front of the waiting space 30. This patient toilet 7 corresponds to a toilet installed adjacent to the standby space 30 and the PET camera room 2, and the flow line of the subject is smoothed and the flow line of the subject is shortened. Is done.
[0059]
On the second floor, a left-right passage leading from the back of the operation room / interpretation room 1 to the medical worker stairs 27, that is, a medical worker passage 91 is disposed. This medical staff passage 91 is disposed adjacent to the back PET camera room 2, the treatment room 6, and the radiopharmaceutical examination room 12, from the operation room / interpretation room 1 to the treatment room 6, the radiopharmaceutical examination room 12, It serves as an access passage to the hot lab 10 on the first floor.
[0060]
Incidentally, as shown in FIG. 8, each camera room 2 has an entrance for a medical worker on the side of the operation room / interpretation room 1 and a side of a space 30 that also serves as the passage 3 for the subject. Individual entrances are provided for facilitating access to each camera room 2 and preventing crossing of flow lines between the subject and the medical staff.
[0061]
The same applies to the treatment room 6. In the treatment room 6, an entrance for a medical worker is provided on the side of the medical worker passage 91, and the subject 30 is provided on the side of the space 30 that also serves as the passage 3 for the subject. In addition to facilitating access to the treatment room 6, the crossing of the flow lines between the subject and the medical staff is prevented. The treatment room 6 is equipped with the already described radiopharmaceutical transport elevator 24 so that the radiopharmaceutical can be obtained from the hot lab 10 on the first floor without being transported manually. .
[0062]
In the non-management area on the second floor, a reception 82B, an interview waiting room 83, an interview room 84, a stairway 85 connecting the first floor and the second floor, the elevator 86, a changing room 8 for the subject, and the like are arranged.
[0063]
In addition, Reference example The PET facility F of the Thing The patient's flow line is separated, and the treatment room 6, the plurality of PET camera rooms 2, and the subject toilet 7 are adjacent to a waiting space (subject stay space) 30 where the subject stays after administration of the radiopharmaceutical. It can be said that it has the arrangement arranged. In addition, the flow line of the patient who finishes in the radiation control area and the flow line of the medical staff are separated, and the entrance / exit of the plurality of PET camera rooms 2, the entrance / exit of the treatment room 6, and the entrance / exit of the toilet 7 for the subject are separated. Thus, it can be said that the structure is arranged facing the waiting space (stay space) 30 of the subject. Furthermore, the operation / interpretation room (medical worker stay space) 1 in which the medical staff always stays is arranged on the opposite side of the standby space 30 so as to sandwich the treatment room 6 and the plurality of PET camera rooms 2. It can be said that. In this regard, the first embodiment to the first embodiment in which the respective entrances and exits of the plurality of PET camera rooms 2 and the entrance and exit of the treatment room 6 are arranged so as to face the space (operation room / reading room 1) where medical staff stay. Different from the PET facility of the fifth embodiment.
[0064]
Then explained above Reference example The operation of the PET facility F will be described (see FIGS. 7 and 8).
The subject enters the PET facility F from the entrance 81 on the first floor, receives at the reception 82A, and goes to the second floor through the stairs 85 or the elevator 86. The subject who has entered the unmanaged area on the second floor waits for an inquiry in the interview waiting room 83 after registering at the reception 82B on the second floor. A subject who has received an inquiry by a doctor in the interview room 84 changes into a change of clothes in the changing room 8 for the subject (there may not be a change of clothes).
[0065]
The subject who changed into clothes enters the management area and is given a radiopharmaceutical containing a radionuclide in the treatment room 6, and then moves to a waiting space 30 that also serves as a passage for the subject, a rest room 4, and a recovery room 5. To do. Then, in order to stabilize the distribution of the radiopharmaceutical in the body, the standby space 30 waits for about 50 minutes. The subject urinates in the subject toilet 7 arranged on the front side of the waiting space 30 and passes through the subject passage 3 to the PET camera room 2 to be examined. Specifically, the subject takes a picture in one of the three PET camera rooms 2 (PET camera 21), which is determined in advance.
[0066]
After imaging, the subject returns to the waiting space 30 and waits for about 60 minutes in the recovery room 5 in order to wait for the administered radionuclide to decay. In some cases, no waiting is performed in the recovery chamber 5.
[0067]
The subject waits in the waiting space 30 and then leaves the management area through the contamination examination room 9. Changing clothes is performed in the changing room 8 for the subject in the unmanaged area as necessary. The above is the flow line of the subject.
[0068]
According to this configuration, the waiting space 30 faces the entrance / exit of each PET camera room 2, the entrance / exit of the treatment room 6, the entrance / exit of the toilet 7 for the subject, etc., so that the flow lines of the subject can be clarified. And shortening can be achieved. In addition, the flow lines of the subject and the medical staff can be reliably separated. In addition, by clarifying and shortening the flow line of the subject, explanation (guidance) of the flow line to the subject of the medical staff becomes easy, and the work load of the medical staff is reduced. In addition, it is possible to make contact between the medical staff and the subject in a short time. In addition, the physical burden on the subject is reduced as the flow line of the subject becomes shorter.
[0069]
On the other hand, as can be easily understood from FIG. 8, the medical staff does not enter the waiting space 30 except for the non-stationary work such as the care of the subject. PET camera photography can be performed. That is, by adopting the above-described layout, as in the first embodiment, it is possible to prevent the crossing of the flow line of the subject and the flow line of the medical worker, and to reduce the exposure dose of the medical worker. It becomes possible.
[0070]
In addition, when a medical worker in the management area on the second floor has a business in the management area on the first floor, it is possible to go to the management area on the first floor through the medical worker passage 91 and the stairs 27 for medical workers. it can. At this time, there is no crossing with the flow line of the subject. By the way, since there is an entrance / exit of the hot lab 10 in front of you when you get down to the first floor, it is easy to access the hot lab 10 from the second floor. Also, conversely, access from the hot lab 10 to the second floor is easy.
[0071]
By the way, Reference example Then, the radiopharmaceutical transport elevator 24 is provided to transport the radiopharmaceutical produced and dispensed by the synthesizer and the dispenser in the hot laboratory 10 to the treatment room 6 on the second floor, thereby minimizing the flow of the radiopharmaceutical. ing. That is, the radiopharmaceutical dispensed in the syringe is put in a shielding container and conveyed to the treatment room 6 by the radiopharmaceutical transport elevator 24, and the used syringe is returned to the hot lab 10 by the radiopharmaceutical transport elevator 24. It is stored in the waste storage room 17. Thus, by minimizing the flow line of the radiopharmaceutical, the exposure of the medical staff can be reduced.
[0072]
Moreover, since the hot laboratory 10 is arrange | positioned on the 1st floor (lower floor), the exposure dose of the medical worker of the hot laboratory 10 by the subject who received the radiopharmaceutical can be reduced.
[0073]
That means Reference example According to, the problem of separating the flow line between the subject and the health care worker (the task of reducing the exposure dose received by the health care worker from the subject, the labor saving of the work of guiding and guiding the subject, etc. ), The problem of reducing the burden on the subject by shortening the flow line of the subject is solved.
[0074]
The present invention described above can be widely modified without being limited to the above-described embodiments. For example, you may make it implement combining each embodiment suitably. Moreover, the heavy objects such as the cyclotron may be installed on the ground floor, the first floor, or the second floor of the PET facility, and the floor is not particularly limited. Moreover, it is good also as a structure which arrange | positions a hot laboratory in an upper floor and a rest room and a recovery room in a lower floor. Moreover, it is good also as a structure which arrange | positions the whole on one floor. In addition, a gamma-ray shielding screen is placed between the bed provided in the rest room or the sofa provided in the recovery room so that the subject receives less radiation from other subjects. Good. Moreover, as already described, the PET facility is a medical facility that operates emission CT, that is, SPECT, PET, and the like, and is not limited to the PET facility. The PET camera also includes an emission CT camera such as SPECT.
[0075]
In addition, although the changing room 8 for the subject (see the drawings and the like) is arranged in the non-management area, it may be arranged in the management area. Further, the inquiry waiting room 83 and the inquiry room 84 may also be arranged in the management area.
