Abstract

There is provided a control device that decides at least one medical image as a medical image to display or save from among medical images taken by a plurality of imaging devices, on a basis of imaging device status information that includes information about a position or an attitude for at least one of the plurality of imaging devices.

First claim

The invention claimed is:

1. A medical control device for a medical imaging system, comprising:
processing circuitry configured to
determine a status of each of a plurality of medical imaging devices based on medical imaging device status information that includes three dimensional position and attitude information of each of the plurality of medical imaging devices, wherein
the plurality of medical imaging devices includes a first medical imaging device of a first type and a second medical imaging device of a second type, different from the first type, and
the medical imaging device status information about the second medical imaging device includes information about a distance between the second medical imaging device and a focus point of the second medical imaging device;

select at least one medical image from among a plurality of medical images obtained by the plurality of medical imaging devices when the status of a corresponding medical imaging device satisfies a certain image decision condition, wherein the certain image decision condition includes that an observation target is included in the medical image;
determine whether or not the status of at least one of the plurality of medical imaging devices satisfies the certain image decision condition;
determine, when the first medical imaging device is tilted by a certain angle or more, that the status of the first medical imaging device satisfies the certain image decision condition;
determine, when the focus point of the second medical imaging device is aligned with the observation target, that the status of the second medical imaging device satisfies the certain image decision condition, and
select the at least one medical image from among a plurality of medical images obtained by the first medical imaging device and from among a plurality of medical images obtained by the second medical imaging device based on the respective status of the first medical imaging device and the second medical imaging device satisfying the certain image decision condition; and
output the selected at least one medical image from the plurality of medical images obtained by the plurality of medical imaging devices.

2. The medical control device according to claim 1 , wherein
the plurality of medical imaging devices includes at least one movable camera.

3. The medical control device according to claim 1 , wherein
the first medical imaging device is a movable camera which is a point of view camera, and the second medical imaging device is a surgical field camera, which is installed in a stationary manner inside an operating room.

4. The medical control device according to claim 1 , wherein
the processing circuitry is further configured to select at least two medical images from among the plurality of medical images obtained by the plurality of medical imaging devices.

5. The medical control device according to claim 1 , wherein
the processing circuitry is further configured to discard any medical images of the plurality of medical images obtained by the plurality of medical imaging devices that are not selected.

6. The medical control device according to claim 1 , wherein the processing circuitry is further configured to filter any remaining medical images of the plurality of medical images that are not selected by the processing circuitry by selectively displaying or recording only the selected at least one medical image.

7. The medical control device according to claim 1 , wherein the medical imaging device status information further includes occlusion information and images of the plurality of medical images having the occlusion information indicating surgical field occlusion are not selected.

8. A medical control device for a medical imaging system, comprising:
processing circuitry configured to
determine a status of each of a plurality of medical imaging devices based on medical imaging device status information that includes three dimensional position and attitude information of each of the plurality of medical imaging devices, wherein
the plurality of medical imaging devices includes a plurality of movable cameras, and
the medical imaging device status information about each of the plurality of movable cameras includes information about a position of the respective movable camera and information about a distance between the respective movable camera and a respective focus point of the movable cameras;

select at least one medical image from among a plurality of medical images obtained by the plurality of medical imaging devices when a status of a corresponding medical imaging device satisfies a certain image decision condition, wherein the certain image decision condition includes that an observation target is included in the medical image;
determine whether or not the status of at least one of the plurality of medical imaging devices satisfies the certain image decision condition, wherein when the respective focus point of the respective movable camera is aligned with the observation target, the processing circuitry is configured to determine that the status of the respective movable camera satisfies the certain image decision condition; and
output the selected at least one medical image from the plurality of medical images obtained by the plurality of medical imaging devices.

9. The medical control device according to claim 8 , wherein
at least one of the plurality of movable cameras is a wearable camera.

10. The medical control device according to claim 8 , wherein
at least one of the plurality of movable cameras is attached to a treatment tool used in a medical procedure.

11. The medical control device according to claim 8 , wherein
at least one of the plurality of movable cameras is a microscope camera that obtains an image of an observation target with a microscope being attached to a leading end of an arm.

12. The medical control device according to claim 8 , wherein
at least one of the plurality of movable cameras is an endoscope camera that obtains an image of an observation target with an endoscope being attached to a leading end of an arm.

13. The medical control device according to claim 8 , wherein
at least one of the plurality of movable cameras is an X-ray camera that obtains an X-ray tomographic image while moving relative to a patient body.

14. The medical control device according to claim 8 , wherein
at least one of the plurality of movable cameras is configured to obtain an ultrasound image inside a blood vessel while moving a catheter provided with a transducer on a leading end, inside the blood vessel.

15. A medical control device for a medical imaging system, comprising:
processing circuitry configured to determine a status of each of a plurality of medical imaging devices based on medical imaging device status information that includes three dimensional position and attitude information of each of the plurality of medical imaging devices, wherein the plurality of medical imaging devices includes a first medical imaging device of a first type and a second medical imaging device of a second type, different from the first type, and the medical imaging device status information about the second medical imaging device includes information about a distance between the second medical imaging device and a focus point of the second medical imaging device,
select at least one medical image from among a plurality of medical images obtained by the plurality of medical imaging devices when the status of a corresponding medical imaging device satisfies a certain image decision condition, wherein the certain image decision conditi
