Description

The present invention relates to an image diagnostic apparatus.

2. Description of the Related Art Conventionally, imaging apparatuses for image diagnosis that take images of the inside of a human body are known (for example, see Patent Document 1).

The imaging device for image diagnosis (PET device: positionron emission tomography device) described in Patent Document 1 uses a drug labeled with a positron-emitting nuclide to capture a pair of gamma rays (radiation) generated by the annihilation of an electron and a positron. By detecting , images of the inside of the human body are taken. The captured images are then used for image diagnosis, such as determining the presence or absence of cancer cells. This PET apparatus includes an imaging unit including a detection section that detects gamma rays, a bed on which a human body to be imaged is placed in a supine position, and a rotation mechanism for rotating the imaging unit. The PET apparatus described in Patent Document 1 has a head imaging state in which the head of a human body in a supine position is photographed and a mammography state in which the breasts of a human body in a prone position are photographed by rotating the imaging unit. It is configured so that it can be switched between.

JP2018-31656A

Here, although it is not specified in Patent Document 1, the size of the body part differs depending on the person being photographed, so in order to accurately photograph the target part of the human body, it is necessary to photograph the human body to be photographed. It is necessary to perform detailed positioning of the target region. Therefore, when using the PET apparatus described in Patent Document 1, it is not only necessary to rotate the imaging unit to switch between the head imaging state and the mammography state, but also to rotate the imaging unit, for example, in the head imaging state. When photographing the body, it is necessary to align the head (diagnosis target region) of the human body (subject) lying on the bed. Therefore, in order to perform position alignment, the test worker may assist the test subject lying on the bed to move, or may instruct the test subject to move his/her position. . In other words, it is thought that either the test worker will need to assist the test subject in moving, or the test subject will need to move themselves. Therefore, in a configuration that detects radiation emitted from the diagnosis target area of the examinee, the work burden on the inspection worker and the examinee due to positioning to accurately image the diagnosis target area of the examinee is reduced. There is a desire for an image diagnostic apparatus that can reduce the amount of noise.

This invention has been made to solve the above-mentioned problems, and one object of the invention is to detect radiation emitted from a diagnostic target site of a patient. An object of the present invention is to provide an image diagnostic apparatus that can reduce the work burden on a test worker and a subject due to positioning for accurately imaging a diagnosis target site.

In order to achieve the above object, an image diagnostic apparatus according to one aspect of the present invention includes a bed on which a subject lies and detects radiation emitted from a region to be diagnosed of the subject lying on the bed. , an imaging unit that images the diagnosis target region of the subject, a first imaging preparation position that is an imaging preparation position for imaging the first diagnosis target region of the subject by the imaging unit, and a moving unit that moves the relative position of the bed and the imaging section between a second imaging preparation position that is an imaging preparation position for imaging a second diagnosis target region of the examiner; and a first imaging preparation position or a fine adjustment operation unit that receives an operation for finely adjusting the imaged position of the diagnostic target region of the subject by moving the relative position from the second imaging preparation position; In the case where The sensor is configured to accept an operation for finely adjusting the relative position while the support portion is being detected by the sensor .

In the image diagnostic apparatus according to the first aspect, by moving the relative position of the bed and the imaging unit from the first imaging preparation position or the second imaging preparation position, the position where the diagnostic target region of the subject is imaged can be finely adjusted. It includes a fine adjustment operation section that accepts adjustment operations. As a result, the relative position between the bed and the imaging unit can be adjusted by operating the fine-adjustment operation section without the test worker having to assist the patient in moving, and without the patient having to move himself. Accurate positioning can be achieved while making fine adjustments. As a result, in a configuration that detects radiation emitted from the diagnostic target area of the examinee, the workload on the test worker and the examinee due to positioning to accurately image the diagnostic target area of the examinee is increased. can be reduced. Further, as described above, when imaging the first diagnosis target region, a support part for supporting a predetermined part of the subject and a detection that the support part is installed at a predetermined position are detected. The fine adjustment operation section is configured to receive an operation for finely adjusting the relative position while the support section is being detected by the detection sensor. Thereby, it is possible to suppress the start of movement for finely adjusting the relative position in a state where the support part is not installed at a predetermined position. Therefore, in a state where the predetermined region of the subject is not supported by the support section, it is possible to suppress the movement for finely adjusting the relative position from being started. As a result, by supporting a predetermined part of the examinee, the relative position can be moved for fine adjustment while the predetermined part of the examinee is placed in a predetermined position. , more accurate alignment can be performed.

Further, the fine adjustment switch 43 is an example of a "fine adjustment operation section" in the claims.

The head movement switch 41 receives an operation for moving the imaging unit 2 to the head imaging preparation position 20a in order to image the head 101a. The breast movement switch 42 also accepts an operation to move the imaging unit 2 to the breast imaging preparation position 20b in order to image the breast 101b. Specifically, the imaging unit 2 starts moving toward the head imaging preparation position 20a by receiving an operation on the head movement switch 41 no matter where it is on the path 30. Similarly, the imaging unit 2 starts moving toward the breast imaging preparation position 20b by accepting an operation on the breast movement switch 42 no matter where it is on the path 30. The moving unit 3 moves the imaging unit 2 toward the head imaging preparation position 20a under the control of the control unit 8 while the head movement switch 41 is being operated (pressed down). Similarly, under the control of the control unit 8, the moving unit 3 moves the imaging unit 2 toward the breast imaging preparation position 20b while the breast movement switch 42 is being operated (pressed down).

The fine adjustment switch 43 is configured to accept an operation for finely adjusting the position where the head 101a of the subject 101 is imaged by moving the imaging unit 2 from the head imaging preparation position 20a.

Further, the fine adjustment switch 43 does not accept operation when the imaging unit 2 is located at a position (paths 30a, 30b, and 30c) between the head imaging preparation position 20a and the breast imaging preparation position 20b. The imaging unit 2 is configured to accept an operation when it is in the head imaging preparation position 20a. The fine adjustment switch 43 is configured to accept an operation when the imaging unit 2 is located between the head imaging preparation position 20a and the head imaging start position 20c (route 30d in FIG. 4). Further, the fine adjustment switch 43 is configured to accept an operation when the headrest 5 is detected by the detection sensor 6. When the fine adjustment switch 43 is in a state where no operation is accepted, the imaging unit 2 is configured not to be moved (fine adjustment) even if the fine adjustment switch 43 is pressed by an inspection worker. Further, when the fine adjustment switch 43 is in a state where it can accept an operation, the moving section 3 is configured to move the imaging section 2 while the fine adjustment switch 43 is being operated (pressed down). ing.

For example, the fine adjustment switch 43 can move the imaging unit 2 (radiation detector 22) in the head direction (X1 direction in FIG. 3) or foot direction (X1 direction in FIG. 3) of the subject 101 in the head imaging preparation position 20a. X2 direction), an operation for finely adjusting the position where the head 101a of the subject 101 is imaged is accepted. Specifically, the headrest detection signal is acquired by the detection sensor 6 that detects the headrest 5 while the imaging unit 2 is moved to the head imaging preparation position 20a based on the operation of the head movement switch 41. In this state, the fine adjustment switch 43 accepts operations. Then, based on the operation on the fine adjustment switch 43, the moving section 3 moves the imaging section 2 from the head imaging preparation position 20a to perform fine adjustment (positioning). Then, based on the operation on the fine adjustment switch 43, the imaging unit 2 moves to the head imaging start position 20c, which is a position suitable for imaging the subject 101 (a position for imaging the head 101a, which is the imaging target region). It can be moved while being finely adjusted.

Further, the fine adjustment switch 43 includes an approach direction switch 43a and a departure direction switch 43b. The approach direction switch 43a accepts an operation to finely adjust (move) the imaging unit 2 in a direction to bring it closer to the subject 101 (approach direction). Further, the separation direction switch 43b accepts an operation for finely adjusting (moving) the imaging unit 2 in a direction away from the subject 101 (separation direction). Specifically, the approach direction switch 43a moves the imaging unit 2 in the direction of the head imaging start position 20c (X2 An operation for fine adjustment toward the patient's 101's foot side is accepted. Further, the separation direction switch 43b moves the imaging unit 2 in the direction of the head imaging preparation position 20a (X1 direction, An operation for fine adjustment toward the head side of the examiner 101 is accepted.

That is, the pair of operation panels 4 (fine adjustment switches 43) are provided on each of the side surfaces of the subject 101 in the supine position in the left and right directions (Y1 direction and Y2 direction) on the bed 1. The operation panel 4 has a head movement switch 41, a breast movement switch 42, and , fine adjustment switches 43 (approach direction switch 43a and departure direction switch 43b) are installed. That is, the approach direction switch 43a is installed in the fine adjustment switch 43 on the direction side (X2 direction side) that brings the imaging section 2 closer to the subject 101, and the away direction switch 43b moves the imaging section 2 closer to the subject 101. It is installed on the direction side away from 101 (X1 direction side). Therefore, each of the pair of operation panels 4 is installed with the left and right sides reversed.

(Control processing according to this embodiment)
Next, with reference to FIG. 7, a control processing flow regarding the image diagnosis method by the image diagnosis apparatus 100 according to this embodiment will be described. Further, steps 201 to 209 indicate control processing by the control unit 8.

First, in step 201, it is determined whether an operation on either the head movement switch 41 or the breast movement switch 42 has been accepted. If it is determined that the operation on the head movement switch 41 has been accepted, the process proceeds to step 202. Further, if it is determined that the operation on the breast movement switch 42 has been accepted, the process proceeds to step 206.

In step 202, the imaging section 2 is moved by the moving section 3 toward the head imaging preparation position 20a while the operation on the head movement switch 41 is being accepted. During a period in which operations on the head movement switch 41 are continuously accepted, the imaging section 2 continues to be moved by the moving section 3 toward the head imaging preparation position 20a. Then, when the operation on the head movement switch 41 is stopped or when the imaging section 2 has arrived at the head imaging preparation position 20a, the process proceeds to step 203.

In step 203, it is determined whether the imaging unit 2 is located at the head imaging preparation position 20a. If it is determined that the imaging unit 2 is located at the head imaging preparation position 20a, the process proceeds to step 204. If it is determined that the imaging unit 2 is not located at the head imaging preparation position 20a, the process returns to step 201.

In step 204, it is determined whether the output headrest detection signal is acquired by the detection sensor 6 that detects the headrest 5. If it is determined that the headrest detection signal has been acquired, the process advances to step 205. If it is determined that the headrest detection signal has not been acquired, the system waits until the headrest detection signal is acquired.

In step 205, the position of the imaging unit 2 is finely adjusted based on the input operation to the fine adjustment switch 43. Specifically, based on the input operation to the approach direction switch 43a of the fine adjustment switch 43, the imaging unit 2 moves in the direction in which the moving unit 3 approaches the subject 101 (X2 direction in FIG. 1, the foot of the subject 101). lateral direction). Further, based on the input operation to the separation direction switch 43b of the fine adjustment switch 43, the imaging unit 2 is moved away from the subject 101 by the moving unit 3 (X1 direction in FIG. 1, head side direction of the subject 101). be moved towards. In order to align the head 101a of the subject 101 to the position where imaging starts (head imaging start position 20c), the position of the imaging unit 2 is finely adjusted based on the operation of the fine adjustment switch 43.

In step 206, the imaging section 2 is moved by the moving section 3 toward the breast imaging preparation position 20b while the breast moving switch 42 is being operated. While operations on the breast movement switch 42 continue to be accepted, the imaging section 2 continues to be moved by the moving section 3 toward the breast imaging preparation position 20b. Then, when the operation on the breast movement switch 42 is stopped or when the imaging section 2 has arrived at the breast imaging preparation position 20b, the process proceeds to step 207.

In step 207, it is determined whether the imaging unit 2 is located at the breast imaging preparation position 20b. If it is determined that the imaging unit 2 is located at the breast imaging preparation position 20b, the process proceeds to step 208. If it is determined that the imaging unit 2 is not located at the head imaging preparation position 20a, the process returns to step 201.

In step 208, the imaging unit 2 performs imaging of the imaging target region of the subject 101 (head 101a or breast 101b).

Next, in step 209, the radiation detector 22 of the imaging unit 2 detects radiation (gamma rays) emitted from the diagnosis target site. Then, a captured image is generated based on the acquired detection signal.

Note that in step 204 and step 205, if an operation on the breast movement switch 42 is detected while the imaging unit 2 is being finely adjusted, the process proceeds to step 206, and the imaging unit 2 moves to the breast imaging preparation position 20b. The control may be performed so that it can be moved.

Further, in this embodiment, the inspection operator places the subject 101 lying on the bed 1 while moving the imaging unit 2 to either the head imaging preparation position 20a or the breast imaging preparation position 20b. Make it worse. That is, the examination operator moves the imaging unit 2 between the head imaging preparation position 20a and the breast imaging preparation position 20b without making the subject 101 lie down on the bed 1.

A fine adjustment switch 43 (fine adjustment operation section) is provided that accepts an operation for finely adjusting the imaged position of the diagnosis target region of the subject 101 by moving the relative position. As a result, the bed 1 and the imaging unit 2 can be adjusted by operating the fine adjustment switch 43 without the test worker having to assist the test subject 101 in moving, and without the test subject 101 moving himself. Accurate positioning can be performed while finely adjusting the relative position with the As a result, in a configuration that detects radiation emitted from the diagnosis target site of the subject 101, the inspection worker and the examinee 101 due to positioning for accurately imaging the diagnosis target site of the subject 101. It is possible to reduce the workload of
