Description
この発明は、一般に生体内画像化装置に関し、特に球形、長円体、楕円形または同様の形状を備えた生体内画像化装置に関する。
体内の通路または腔の生体内の画像化を行なうための装置および方法が当該技術分野で既知である。そのような装置は、とりわけ、さまざまな内部の体の腔で画像化を行なうためのさまざまな内視鏡画像化システムおよび装置を含み得る。これら装置の一部は画像データを伝送するために無線接続を使用する。
この発明の一実施例では、生体内画像化装置は、楕円形、球形または実質的に球形の形状を有し得る。別の実施例では、画像化装置は、画像センサを支持するサポート、照明源、サポートの第1の面上のアンテナ、およびサポートの第2の面上の送信機ならびに電池サポートを含み得る。アンテナは、それによって占有される空間の量を低減するために、生体内画像化装置の他の素子に組合わされるかまたはそこに取付けられてもよい。
以下の詳細な説明では、この発明を完全に理解できるように多数の具体的な詳細を説明する。しかしながら、当業者には、この発明はこれら具体的な詳細なしに実現できることが理解されるであろう。場合によっては、周知の方法、手順、構成要素および回路は、この発明をわかりにくくするのを避けるために詳細には説明されていない。
5rのとき、形状は長円体であり得、楕円形ともみなすことができる。一実施例では、rは約11.4mmであり得るが、しかしながら、他の寸法を使用してもよい。なお、装置40が軸について回転され得るとき、装置40のさまざまな断面は異なり得る。たとえば、装置40は、幾分不規則な球形または長円体であってもよい。装置40の形状は、異なる角度から見ると異なることがある。
on a chip)」、マイクロコントローラ等、または他の構成要素であってもよい。送信機54は、一実施例では、たとえば、送信機および/または受信機の能力、コントローラ、照明装置のためのドライバ、およびさまざまなアナログおよび/またはデジタル素子を含み得る汎用の集積装置であってもよい。
図である。図2Bは、この発明の実施例による画像化装置のサポートの底面図である。ここで使用される場合、上面および底面は相対的な言葉であり、文脈に応じて交換可能であり得る。
かもしくは埋込まれることによって、分離素子170内でぐるぐる巻かれるか、またはその内部もしくは実質的にその内部に埋込まれてもよい(一部分が外側に延在してもよい)。図3Aは、一実施例による光学分離素子170およびアンテナ48を示す。図3Bは、一実施例による光学分離素子170およびアンテナ48を示す切欠図である。図3Cは、一実施例によるアンテナ48を示す。図3Aを参照すると、光学分離素子170は、一実施例では円錐形であってもよく、アンテナ48は光学分離素子170の外側に巻きつけられてもよい。図3bを参照すると、アンテナ48は分離素子170の内側にぐるぐる巻かれてもよい。アンテナ48は光学素子170内またはその上に位置付けられる必要はなく、分離素子170は含まれる必要はない。光学分離素子170は他の好適な形状であってもよい(たとえば、図5)。代替の実施例では、異なる形を有する他の好適な数の光学分離素子が使用されてもよい。光学分離素子は、たとえば、照明源または画像センサ、ドームまたはレンズに一体化されるかそこから延在する片、透光性または半透明の部材などの装置の構成要素の延在部であってもよく、もしくは他の好適な形であってもよい。
の部分に容易に向けることができる。
