Abstract

According to embodiment, an image processing apparatus comprising a specifying unit and a display controller. The specifying unit that specifies an acquisition position of an indicator relating to blood flow on a blood vessel-containing image collected by a medical image diagnostic apparatus. The display controller that displays the acquisition position on the blood vessel-containing image and displays the indicator on a display unit in association with the acquisition position.

Claims (31)

1 . An image processing apparatus comprising:

processing circuitry configured to

determine, from each of a plurality of X-ray fluoroscopic images of a subject acquired sequentially, a plurality of measurement locations at which measurement data was acquired by a device,

determine a plurality of reference positions on a single contrast X-ray image of the subject that correspond to the determined plurality of measurement locations, and

cause a display to display a single image in which a plurality of marks are superimposed on the single contrast X-ray image based on the plurality of reference positions, the plurality of marks indicating values related to blood flow calculated from the measurement data.

2 . The image processing apparatus according to claim 1 , wherein the processing circuitry is configured to

determine the plurality of reference positions that correspond to the determined plurality of measurement locations on a single contrast X-ray image acquired prior to the plurality of X-ray fluoroscopic images, and

superimpose the plurality of marks at the determined plurality of reference positions on the single contrast X-ray image, the plurality of marks indicating values related to blood flow calculated from measurement data acquired during acquisition of the plurality of X-ray fluoroscopic images.

3 . The image processing apparatus according to claim 1 , further comprising:

an input interface configured to accept an operation to adjust the determined plurality of reference positions on the single contrast X-ray image.

4 . The image processing apparatus according to claim 3 , wherein the input interface is configured to accept the operation on a vascular centerline extracted from a blood vessel included in the single contrast X-ray image.

5 . The image processing apparatus according to claim 1 , wherein the processing circuitry is configured to cause the display to display a mark string composed of the plurality of marks.

6 . An X-ray diagnostic apparatus comprising:

processing circuitry configured to

acquire a plurality of X-ray fluoroscopic images of a subject and a single contrast X-ray image of the subject injected with contrast agent,

determine, from each of the plurality of X-ray fluoroscopic images of the subject acquired sequentially, a plurality of measurement locations at which measurement data was acquired by a device,

determine a plurality of reference positions on the single contrast X-ray image that correspond to the determined plurality of measurement locations, and

cause a display to display a single image in which a plurality of marks are superimposed on the single contrast X-ray image based on the plurality of reference positions, the plurality of marks indicating values related to blood flow calculated from the measurement data.

7 . The X-ray diagnostic apparatus according to claim 6 , wherein the processing circuitry is configured to acquire the plurality of X-ray fluoroscopic images while the device is drawn out.

8 . The X-ray diagnostic apparatus according to claim 6 , wherein the processing circuitry is configured to cause the display to display a mark string composed of the plurality of marks.

9 . An image processing method comprising:

determining, from each of a plurality of X-ray fluoroscopic images of a subject acquired sequentially, a plurality of measurement locations at which measurement data was acquired by a device;

determining a plurality of reference positions on a single contrast X-ray image of the subject that correspond to the determined plurality of measurement locations; and

causing a display to display a single image in which a plurality of marks are superimposed on the single contrast X-ray image based on the plurality of reference positions, the plurality of marks indicating values related to blood flow calculated from the measurement data.

10 . The image processing method according to claim 9 , further comprising:

determining the plurality of reference positions that correspond to the determined plurality of measurement locations on a single contrast X-ray image acquired prior to the plurality of X-ray fluoroscopic images; and

superimposing the plurality of marks at the determined plurality of reference positions on the single contrast X-ray image, the plurality of marks indicating values related to blood flow calculated from measurement data acquired during acquisition of the plurality of X-ray fluoroscopic images.

11 . The image processing method according to claim 9 , further comprising accepting an operation to adjust the determined plurality of reference positions on the single contrast X-ray image.

12 . The image processing method according to claim 11 , wherein the accepting accepts the operation on a vascular centerline extracted from a blood vessel included in the single contrast X-ray image.

13 . The image processing method according to claim 9 , further comprising acquiring the plurality of X-ray fluoroscopic images while the device is drawn out.

14 . The image processing method according to claim 9 , further comprising causing the display to display a mark string composed of the plurality of marks.
