Abstract

In one embodiment, a medical image processing apparatus used for a treatment using a device includes a memory configured to store a volume data of an object; and processing circuitry configured to acquire positional information of the device, set, in an X-ray image generated by imaging an object using X-ray, a region on which a volume-based 2D image generated from the volume data is to be superimposed, based on the positional information of the device, and generate a superimposed image by superimposing the volume-based 2D image on the set region in the X-ray image.

Claims (44)

1. A medical image processing apparatus used for a treatment using a device, the apparatus comprising:

a memory configured to store a volume data of an object; and

processing circuitry configured to

acquire a real-time X-ray image by imaging an object using X-ray,

acquire positional information of the device,

generate a superimposed image by superimposing a volume-based 2D image generated from the volume data on the real-time X-ray image such that a superimposed region where the volume-based 2D image is superimposed and a non-depicted region where the volume-based 2D image is not superimposed are set based on the positional information of the device, and

move a position of the superimposed region and a position of the non-depicted region, in accordance with a movement of the device.

2. The medical image processing apparatus according to claim 1 ,

wherein the positional information of the device includes coordinates of a tip portion of the device.

3. The medical image processing apparatus according to claim 2 ,

wherein the positional information of the device further includes coordinates of a portion of the device other than the tip portion of the device.

4. The medical image processing apparatus according to claim 1 ,

wherein the processing circuitry is configured to display the superimposed image such that a region including the device in the volume-based 2D image is not depicted based on the positional information of the device.

5. The medical image processing apparatus according to claim 4 ,

wherein the processing circuitry is configured to display the superimposed image such that the region where the volume-based 2D image is not depicted is moved depending on a movement of the device.

6. The medical image processing apparatus according to claim 5 ,

wherein the processing circuitry is configured to display the superimposed image such that an additional region in the volume-based 2D image, located a predetermined distance or more away from a tip of the device in a traveling direction of the device, is not further depicted.

7. The medical image processing apparatus according to claim 6 ,

wherein the processing circuitry is configured to

receive setting of a fixed region where the volume-based 2D image is fixedly displayed, and

display the superimposed image such that the fixed region in the volume-based 2D image is fixedly depicted regardless of the movement of the device, while the region including the device and the additional region in the volume-based 2D image are moved, depending on the movement of the device.

8. The medical image processing apparatus according to claim 1 ,

wherein the X-ray image is a real-time X-ray image.

9. The medical image processing apparatus according to claim 1 ,

wherein the processing circuitry is configured to

set a transparency at each position of the volume-based 2D image in the superimposed image, based on the positional information of a device,

superimpose the volume-based 2D image, which has the set transparency, on the X-ray image.

10. A medical image processing apparatus used for a treatment using a device, the apparatus comprising:

a memory configured to store a volume data of an object; and

processing circuitry configured to

acquire a real-time X-ray image by imaging an object using X-ray,

acquire positional information of the device,

generate a superimposed image by superimposing a volume-based 2D image generated from the volume data on the real-time X-ray image such that a superimposed region where the volume-based 2D image is superimposed and a transparent region where the volume-based 2D image is superimposed with a predetermined transparency are set based on the positional information of the device, and

move a position of the superimposed region and a position of the transparent region, in accordance with a movement of the device.

11. An X-ray diagnostic apparatus that comprises the medical image processing apparatus of claim 1 .

12. An X-ray diagnostic apparatus that comprises the medical image processing apparatus of claim 10 .

13. A medical image processing method comprising:

acquiring a real-time X-ray image by imaging an object using X-ray,

acquiring positional information of a device; and

at least one of:

(a) generating a superimposed image by superimposing a volume-based 2D image on the real-time X-ray image such that a superimposed region where the volume-based 2D image is superimposed and a non-depicted region where the volume-based 2D image is not superimposed are set based on the positional information of the device, and

moving a position of the superimposed region and a position of the non-depicted region, in accordance with a movement of the device, and

(b) generating a superimposed image by superimposing a volume-based 2D image generated from the volume data on the real-time X-ray image such that a superimposed region where the volume-based 2D image is superimposed and a transparent region where the volume-based 2D image is superimposed with a predetermined transparency are set based on the positional information of the device, and

moving a position of the superimposed region and a position of the transparent region, in accordance with a movement of the device.
