Medical imaging system and medical imaging processing apparatus

1. A medical imaging system comprising:

an imaging device comprising a radiation source that generates a radiation for imaging and obtains a medical image or data used for generating the medical image by imaging a subject;

a camera that photographs the imaging device and the subject and outputs a camera image;

a processor configured to store positioning data for specifying an arrangement of the subject with respect to the imaging device; and

a display device comprising a screen that three-dimensionally displays the arrangement of the subject with respect to the imaging device by using the positioning data in a case where the subject is imaged using the imaging device, wherein the camera is movable in a specific direction with respect to the imaging device as the specific direction is changeable, and

the display device is configured to, in response to the specific direction having been changed, adjust displaying of the arrangement of the subject in accordance with an orientation of the imaging device captured in the camera image.

2. The medical imaging system according to claim 1 ,

wherein the positioning data three-dimensionally specifies a position, a posture, and a shape of the subject.

3. The medical imaging system according to claim 1 ,

wherein the positioning data is data relating to the subject, data relating to another subject different from the subject, or schematic model data.

4. The medical imaging system according to claim 3 ,

wherein, in a case where the positioning data is the data relating to the subject, the positioning data is data representing the arrangement of the subject with respect to the imaging device in past imaging.

5. The medical imaging system according to claim 3 ,

wherein the processor is further configured to store the positioning data relating to the other subject similar in shape and size to the subject in association with the subject in a case where the positioning data is the data relating to the other subject.

6. The medical imaging system according to claim 1 ,

wherein the display device displays the arrangement of the subject in a mode showing a three-dimensional position, posture, and shape of the subject.

7. The medical imaging system according to claim 6 ,

wherein the display device displays the three-dimensional shape of the subject in a mode showing unevenness of the subject.

8. The medical imaging system according to claim 1 ,

wherein the processor is further configured to:

determine a difference between the subject and the arrangement of the subject displayed by the display device, and

prohibit the imaging device from imaging the subject in a case where determination is made that there is the difference.

9. The medical imaging system according to claim 8 ,

wherein the processor is further configured to determine the difference by using a distance, an angle, or a volume between the subject and the arrangement of the subject displayed by the display device.

10. The medical imaging system according to claim 1 ,

wherein the processor is further configured to:

detect the subject with respect to the imaging device from a plurality of locations in a case where the subject is imaged using the imaging device, and

generate the positioning data by using a result of the detection.

11. A medical imaging processing apparatus comprising:

an imaging device comprising a radiation source that generates a radiation for imaging and obtains a medical image or data used for generating the medical image by imaging a subject;

a camera that photographs a radiographic unit and the subject and outputs a camera image;

a processor configured to:

store positioning data for specifying an arrangement of the subject with respect to the imaging device by using the positioning data in a case where the subject is imaged using the imaging device, and

a display device comprising a screen that three-dimensionally displays the arrangement of the subject with respect to the imaging device by using the positioning data in a case where the subject is imaged using the imaging device, wherein the camera is movable in a specific direction with respect to the imaging device as the specific direction is changeable, and

the display device is configured to, in response to the specific direction having been changed, adjust displaying of the arrangement of the subject in accordance with an orientation of the imaging device captured in the camera image.
