Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to 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. This invention relates to a PET facility for reducing the risk.
[0002]
[Prior art]
Using radionuclide as a tracer and tomographic imaging of its distribution in the body, the probability of early detection of cancer is markedly increased by the dynamic function test and the PET screening that can observe the metabolism of the body cells. 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.
[0003]
PET screening is performed as follows within the radiation control area. First, in the treatment room ¹⁸ A radiopharmaceutical containing a radionuclide such as F is administered, and the subject is rested in a rest room for about 50 minutes in order to stabilize the distribution of the radiopharmaceutical in the body. Shoot in the shooting room. After imaging, in order to wait for the administered radionuclide to decay, the subject is allowed to wait in the recovery room for about 60 minutes and then exits the radiation control area.
[0004]
During this time, the subject to whom the radiopharmaceutical has been administered moves greatly within the radiation control area. That is, unlike other radiation facilities such as X-ray CT, at the PET facility, the subject is the subject, and the subject moves greatly within the radiation control area during the examination.
[0005]
The dose rate on the body surface of the subject immediately after administration of the radiopharmaceutical is approximately several hundred μSv / h. When a medical worker stays in the vicinity of a subject for a long time and engages in medical work every day, there is a risk of exceeding the annual dose limit (up to 50 mSv per year) stipulated in the Radiation Hazard Prevention Law.
[0006]
Therefore, in order to reduce the exposure dose of the medical staff, it is necessary to avoid the approach between the examinee and the medical staff. For this reason, there are known PET facilities that are designed to completely separate the patient lead (subject flow) and the staff lead (medical worker flow) other than the entrance to the radiation control area (for example, non-existing).

[Problems to be solved by the invention]
By the way, with the increasing demand for PET screening, it is important to reduce the radiation dose of medical workers (doctors, radiographers, nurses, etc.) at PET facilities. In the rest room, the recovery room where the subject waits after photographing with the PET camera, a plurality of subjects stay for a long time, so that the radiation source intensity increases locally. For this reason, it is desired to reduce the exposure dose of a medical worker by a subject waiting (staying) in a rest room or a recovery room. Moreover, in the conventional facility, the number of subjects may be small, and the rest room and the recovery room are not arranged apart from the hot lab in which the radiopharmaceutical administered to the subjects is synthesized and dispensed. For this reason, it is desired to reduce the exposure dose of medical personnel in a hot laboratory. In reducing the exposure dose, it is desirable to ensure smooth flow lines for both the subject and the medical staff.
[0009]
Therefore, the present invention ensures smooth flow lines for both the subject and the medical staff even when the demand for PET screening increases. In the hot lab health care worker From subjects in the waiting area The main purpose is to provide a PET facility in which the exposure dose is reduced.
[0010]
[Means for Solving the Problems]
To reduce the exposure dose of medical personnel and to ensure a smooth flow line between the two, avoid the approach between the subject and the medical staff after administration of the radiopharmaceutical, and the flow line and medical treatment of the subject Separate the flow lines of workers (make sure the flow lines do not cross). Also, at least a PET camera room or a PET camera room and an operation room / interpretation room are arranged between a waiting place where the subject waits (rest room, recovery room) and a hot lab where radiopharmaceuticals are synthesized and dispensed, Reduce exposure of health care workers working in hot labs. A more specific solution will be clarified in the following description of the embodiment.
[0011]

In the cyclotron chamber 13, ¹⁸ A cyclotron (accelerator) 23 for producing nuclides such as F is provided.
[0015]
That is, the management area of the PET facility A of the first embodiment is the waiting space for the subject, the passage for the subject, the common passage for the subject / medical worker from the left side to the right side of FIG. The configuration is such that a part, a work space and passage for a medical worker, a work space for a medical worker, and a device installation space are arranged in this order. In addition, the code | symbol 15 is an air-conditioning wastewater treatment room in a management area, and the code | symbol WC in a radiation management area is a toilet for medical workers. Reference numeral 17 denotes an RI storage room.
[0016]
As shown in FIG. 1, the hot lab 10 is separated from the rest room 4 and the recovery room 5 by at least a distance corresponding to one side of the PET camera room 2. In addition, each camera room 2 and treatment room 6 are provided with an entrance / exit of a medical worker on the side of the operation room / interpretation room 1 and an entrance / exit for the subject on the side of the passage 3 for the subject, While facilitating access to each camera room 2, the crossing of the flow line is prevented (the flow line of the subject and the flow line of the medical staff are separated).
[0017]
That is, the PET facility A of the first embodiment separates the subject's flow line and the medical worker's flow line so as not to cross each other, and the rest room 4 and the recovery room 5 (standby place) are separated from the hot lab 10. To at least a distance corresponding to one side of the PET camera room 2.
[0018]
In addition, the PET facility A of the first embodiment includes a rest room 4 and a recovery room 5, a subject passage 3, a plurality of PET camera rooms 2, an operation room / interpretation room 1 where medical staff always stay, a hot lab 10 And at least the PET camera room 2 is arranged between the rest room 4 and the recovery room 5 and the hot lab 10.
[0019]
Furthermore, in the PET facility A of the first embodiment, the PET camera room 2 and the patient passage 3 are disposed between the rest room 4 and the recovery room 5 and the operation room / interpretation room 1, and the operation room. The reading room 1 and the treatment room 6 are disposed adjacent to each other, and at least the PET camera room 2 is disposed between the waiting place (the rest room 4 and the recovery room 5) and the hot lab 10.
[0020]
Next, the operation of the PET facility A of the first embodiment will be described.
The subject enters the PET facility A from the entrance 81, registers at the reception 82, and waits for an inquiry in the interview waiting room 83. A subject who has received an inquiry by a doctor in the interview room 84 enters the management area, and changes into a change of clothes in the changing room 8 for the subject. In some cases, the subject does not change clothes.
[0021]
Subjects who changed their clothes were treated with radionuclides (for example, as described above) in the treatment room 6. ¹⁸ After the radiopharmaceutical containing F) is administered (oral administration, airway administration, subcutaneous administration), it passes through the passage 3 for the subject and moves to the rest room 4. And in this rest room 4, it waits for about 50 minutes in order to aim at normalization of the biodistribution of a radiopharmaceutical. The subject urinates in the subject toilet 7 after waiting and before photographing, moves to the PET camera room 2 through the subject passage 3, and is examined. That is, the subject takes a picture in one of the three PET camera rooms 2 (PET camera 21).
[0022]
After imaging, the subject moves to the recovery room 5 through the subject passage 3. In this recovery chamber 5, it waits for about 60 minutes to wait for the decay of the administered radionuclide. Depending on the half-life of the administered nuclide, the recovery chamber 5 may not be on standby. By the way, ¹⁸ The half-life of F is about 110 minutes.
[0023]
The subject waits in the recovery room 5, passes through the subject passage 3, changes to the original clothes in the subject changing room 8, and then exits the management area through the contamination examination room 9. To do. The above is the flow line of the subject.
[0024]
On the other hand, as can be easily understood from FIG. 1, medical personnel (doctors, radiologists, etc.) do not pass through the subject passage 3 except for non-stationary work such as care for the subject. Without entering the rest room 4, it is possible to carry out an inquiry (physician), radiopharmaceutical administration, and PET camera photography (radiologist) to the subject. That is, by adopting the above-described layout, it is possible to separate the flow line of the subject and the flow line of the medical staff and reduce the exposure dose of the medical staff.
[0025]
In the PET camera room 2, the medical staff issues an instruction to lay the subject on the bed of the PET camera 21. In the operation room / interpretation room 1, the operation of the PET camera 21 using the console 22, the interpretation of the imaging result of the PET camera 21, and the like are performed. The hot lab 10 synthesizes and dispenses a radiopharmaceutical to be administered to the subject. Further, in the radiopharmaceutical assay room 11, the synthesized radiopharmaceuticals are assayed. In the cyclotron chamber 13, a cyclotron 23 is used. ¹⁸ Production of nuclides such as F.
[0026]
By the way, in the rest room 4 that waits for the subject after administration of the radiopharmaceutical and the recovery room 5 that waits for the subject after the examination (imaging), the capacity increases in proportion to the number of PET cameras and the operation rate. The radiation source intensity in the rest room 4 and the recovery room 5 increases. This increase in the source intensity leads to an increase in the radiation dose of medical personnel.
[0027]
However, in the PET facility A of the present embodiment, as shown in FIG. 1, the PET camera room 2 is located between the rest room 4 and the recovery room 5 and the operation room / interpretation room 1 or hot lab 10 where medical personnel always stay. In addition, the layout for separating the distance between the rest room 4 and the recovery room 5 from the operation room / reading room 1 and the hot laboratory 10 is adopted. That is, the operation room / interpretation room 1 and the hot lab 10 are configured to be separated from the rest room 4 and the recovery room 5 by at least a distance corresponding to one side of the PET camera room 2. For this reason, the radiation dose from the subject of the medical staff working in the operation room / interpretation room 1 or the hot laboratory 10 can be reduced. In particular, the hot lab 10 is further away from the rest room 4 and the recovery room 5 by a distance equal to or shorter than the short side of the operation room / reading room 1. For this reason, the radiation dose from the subject of the medical staff working in the hot lab 10 can be further reduced.
[0028]
In other words, by adopting such a layout (arrangement structure), the patient waiting area (rest room 4 and recovery room 5) where the source intensity locally increases and the medical worker working area (operation room / interpretation) The room 1, the hot laboratory 10, the radiopharmaceutical test room 11, and the blood test room 12) can be remoted, and the exposure dose of the medical staff can be reduced.
[0029]
In addition, by adopting such a layout, the flow lines of both the subject and the medical staff are not interlaced, so that smooth flow lines of both the subject and the medical staff are ensured and the medical staff is engaged. The workability of the worker is improved and the exposure dose of the medical staff is reduced.
[0030]
Further, in the PET facility A of the present embodiment, as shown in FIG. 1, an operation room / interpretation room 1 where medical personnel always stay and a treatment room 6 for administering a radiopharmaceutical to a subject are adjacent. For this reason, the flow line of a medical worker (doctor) can be shortened, the burden on the medical worker can be reduced, and the efficient operation of the PET facility A becomes possible.
[0031]
Moreover, since the PET camera room 2 and the treatment room 6 are arranged in parallel with respect to the hot laboratory 10, unlike the case where the PET camera room 2 is arranged in series, the hot laboratory 10 and the PET camera room 2 are generally equal. It can be a distance. Therefore, any PET camera room 2 can be similarly accessed.
[0032]
In addition, by adopting such a layout, it is possible to reduce the thickness of the shield for achieving the allowable limit of the exposure dose, and thus it is possible to reduce the cost of constructing the PET facility. .
[0033]
<< Second Embodiment >>
Next, the PET facility of the second embodiment will be described.

The medical worker 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 has a role as an access passage to the hot lab 10 on the first floor.
[0038]
Incidentally, as shown in FIG. 3, 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 the waiting space 30 that also serves as the passage 3 for the subject. Each entrance for the examiner is provided to facilitate access to each camera room 2 and prevent crossing of the flow lines between the subject and the medical staff.
[0039]
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. .
[0040]
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.
[0041]
That is, the PET facility B of the second embodiment separates the flow line of the subject and the flow line of the medical staff, and the rest room 4 and the recovery room 5 (standby place) are different from the hot lab 10. It has a configuration arranged in
[0042]
The PET facility B of the second embodiment includes a waiting place 30 (rest room 4 and recovery room 5), a plurality of PET camera rooms 2, an operation room / reading room 1, a hot lab 10, and a rest room 4 and recovery room. The room 5 and the hot lab 10 are also arranged on different floors.
[0043]
In the PET facility B of the second embodiment, the PET camera room 2 and the patient passage 3 are disposed between the rest room 4 and the recovery room 5 and the operation room / interpretation room 1, and the operation room. The reading room 1 and the treatment room 6 are arranged adjacent to each other, and the rest room 4, the recovery room 5, and the hot lab 10 are arranged on different floors.
[0044]
Furthermore, the PET facility B of the second embodiment includes an operation room / interpretation room 1, a treatment room 6, a passage 91 for medical personnel connecting the operation room / interpretation room 1 and the treatment room 6, and a waiting space 30. It is also a configuration in which the PET camera room 2 in which at least the PET camera 21 is installed is disposed between the hot labs 10.
[0045]
Next, the operation of the PET facility B of the second embodiment will be described.
The subject enters the PET facility B 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). Incidentally, the changing room 8 for the subject is arranged in the management area in the first embodiment, but is arranged in the non-management area in the second embodiment.
[0046]
The changed subject enters the management area, is administered a radiopharmaceutical containing a radionuclide in the treatment room 6, and then moves to a waiting space 30 that also serves as the subject passage 3 and the rest room 4. 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 toilet 7 for the subject arranged on the near side of the waiting space 30 that also serves as the resting room 4 before photographing after the waiting for resting, passes through the passage 3 for the subject, and the PET camera room 2 Go to and get an inspection. Specifically, the subject takes a picture in one of the three PET camera rooms 2 (PET camera 21), which is determined in advance.
[0047]
After imaging, the subject returns to the waiting space 30 that also serves as the subject passage 3 and the recovery chamber 5 and waits for about 60 minutes in the recovery chamber 5 in order to wait for the decay of the administered radionuclide. In some cases, no waiting is performed in the recovery chamber 5.
[0048]
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. The above is the flow line of the subject.
[0049]
On the other hand, as can be easily understood from FIG. 3, 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.
[0050]
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.
[0051]
FIG. 4A is a perspective view (bird's eye view) of the first floor portion. The front corner portion of the drawing is the entrance 81 (see FIG. 2), and the room shielded by the thick wall at the back of the drawing is the cyclotron chamber 13. become. FIG. 4B is a perspective view (bird's eye view) of the second floor portion. The room at the front corner of the drawing is the interview waiting room 83, and the elongated operation room / reading room 1 and the medical worker passage 91 on the back side. There is.
[0052]
By the way, as in the first embodiment, in the waiting space 30 (rest room 4, recovery room 5,...) That waits for the subject after administration of the radiopharmaceutical or the subject after the examination (imaging), the PET camera 21. Accommodating personnel increase in proportion to the number of units and the operation rate, and the radiation source strength in the rest room 4 and the recovery room 5 increases. This increase in the source intensity leads to an increase in the radiation dose of medical personnel.
[0053]
However, in the PET facility B of the second embodiment, as shown in FIG. 2 to FIG. 4, the hot lab 10 and the waiting space 30 that also serves as the patient waiting place 4 and the recovery room 5 are separated. Located on the floor. In this way, when both 10 and 30 are arranged on different floors, the radiation is shielded and attenuated by a floor that is far away from the wall and thicker than the wall, so that the medical staff in the hot lab 10 is exposed from the subject. The dose can be reduced.
[0054]
Of course, the waiting room 30 and the operation room / interpretation room 1 where the medical staff always stays are separated by at least a distance corresponding to one side of the PET camera room 2. For this reason, similarly to the first embodiment, it is possible to reduce the exposure dose of the medical staff working in the operation room / interpretation room 1 from the subject.
[0055]
Also, in the PET facility B of the second embodiment, as shown in FIG. 1, an operation room / interpretation room 1 where medical personnel always stay and a treatment room 6 where a doctor administers a radiopharmaceutical to a subject are adjacent. Therefore, the flow of the doctor can be shortened to reduce the burden on the doctor, and the PET facility B can be operated efficiently.
[0056]
Further, in the PET facility B of the second embodiment, a radiopharmaceutical transport elevator 24 is provided to transport the radiopharmaceutical produced and dispensed by the synthesizer and dispenser in the hot lab 10 to the treatment room 6 on the second floor. This minimizes the flow of radiopharmaceuticals. 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.
[0057]
In the second embodiment, the toilet 7 for the subject is disposed adjacent to the PET camera room 2 and the rest room 4. Since the subject waits in the rest room 4 and then urinates in the toilet 7 for the subject and moves to the PET camera room 2, the flow line of the subject can be shortened. By shortening the flow line of the subject, the possibility of contact exposure with the medical staff can be reduced, and the burden on the subject can be reduced.
[0058]
In the second embodiment, since the medical staff staircase 27 connecting the first floor and the second floor is installed in the management area, the floor can be used without waiting or approaching the subject after the test. Can be moved. For this reason, it becomes possible to reduce the exposure of a medical worker. In addition, it becomes possible to prevent the reduction | decrease in the air cleanliness of the hot laboratory 10 by the raising / lowering of a medical worker's staircase by installing the medical staff's stairway 27 on the outer side of the hot laboratory 10.
[0059]
That is, by adopting such a layout, it is possible to provide a PET facility in which smooth flow lines of both the subject and the medical staff are ensured and the exposure dose of the medical staff is reduced. In addition, by adopting such a layout, it is possible to reduce the thickness of the shield for achieving the allowable limit of the exposure dose, and thus it is possible to reduce the cost of constructing the PET facility. .
[0060]
<< Third Embodiment >>
Next, a PET facility according to the third embodiment will be described.
5 and 6 are diagrams showing a PET facility according to the third embodiment, and exemplify the layout of the building of the PET facility having a multi-storey structure in order to reduce the building area and the site area. Among these, FIG. 5 is a plan view of a lower floor where heavy objects such as cyclotrons are arranged, and FIG. 6 is a plan view of an upper floor where a PET camera is installed.
[0061]
In the third embodiment, the flow line separation between the subject and the medical staff is substantially as illustrated in the first embodiment, and the rest room 4 and the recovery room 5 and the hot lab 10 are remoted. Since it is almost as illustrated in the second embodiment, the description will be omitted. In addition, about the part which is common in 1st Embodiment and 2nd Embodiment, suppose that the same code | symbol is attached | subjected and the description is abbreviate | omitted.
[0062]
As shown in FIG. 5, the hot laboratory 10 is also installed on the lower floor (hereinafter referred to as “first floor”) of the PET facility C of the third embodiment. A person's staircase 27 is provided and is connected to the treatment room 6 on the upper floor (hereinafter referred to as “second floor”). This facilitates access to the treatment room 6 where the number of trips is large. This point is different from the PET facility B of the second embodiment. The hot laboratory 10 is provided with a radiopharmaceutical transport elevator 24, a synthesizer 25, and a dispenser 26. Incidentally, although the synthesizer 25 and the dispenser 26 are omitted in FIG. 1 of the first embodiment and FIG. 2 of the second embodiment, they are also used in the hot lab in the first embodiment and the second embodiment. 10 is provided.
[0063]
Moreover, as shown in FIG. 6, the passage 18 for unsteady work is arrange | positioned between the PET camera rooms 2 on the 2nd floor of PET facility C of 3rd Embodiment. This passage 18 makes it possible to access the subject immediately when it is necessary to care for the subject waiting in the rest room 4 or the recovery room 5 while the three PET cameras are operating. It becomes. Further, by using it as an evacuation route in the event of an emergency such as the occurrence of a fire, the subject can be evacuated immediately and guided to the emergency staircase 28. In addition, the configuration of the PET facility C provided with the passage 18 for unsteady operation in this manner is that “the passage connecting the operation room / interpretation room and the passage for the subject is defined between the plurality of PET camera rooms”. This corresponds to the configuration of “PET facility provided at least one in
