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 (35)

1. An image processing apparatus comprising:

processing circuitry configured to

determine a position of a pressure sensor that is inserted into a subject from each of a plurality of X-ray fluoroscopic images acquired sequentially, and determine positions on a contrast X-ray image of the subject that correspond to the determined positions of the pressure sensor,

accept an operation to change the determined corresponding positions on the contrast X-ray image via a user interface on the contrast X-ray image displayed on a display, and

cause the display to display the contrast X-ray image on which marks derived from output of the pressure sensor are superimposed, the marks being set to positions based on the changed corresponding positions on the contrast X-ray image.

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

determine positions on the contrast X-ray image acquired before the plurality of X-ray fluoroscopic images that correspond to positions of the pressure sensor specified in the plurality of X-ray fluoroscopic images, and

cause the display to display the contrast X-ray image in which each position of a blood vessel is color-coded with different colors corresponding to values of an indicator relating to blood flow derived from output of the pressure sensor collected at a time of the plurality of X-ray fluoroscopic images acquisition.

3. The image processing apparatus according to claim 1 , wherein the user interface includes a vascular core line from a coronary tree on the contrast X- ray image, and the processing circuitry is configured to accept a sliding operation on the vascular core line to change the determined corresponding positions on the contrast X-ray image.

4. The image processing apparatus according to claim 1 , wherein the processing circuitry is configured to cause the display to display information relating to necessity of treatment on the contrast X-ray image.

5. An X-ray diagnostic apparatus comprising:

processing circuitry configured to

acquire a contrast X-ray image of a subject and sequentially acquire a plurality of X-ray fluoroscopic images of the subject,

determine a position of a pressure sensor that is inserted into the subject from each of the plurality of X-ray fluoroscopic images, and determine positions on the contrast X-ray image that correspond to the determined positions of the pressure sensor,

accept an operation to change the determined corresponding positions on the contrast X-ray image via a user interface on the contrast X-ray image displayed on a display, and

cause the display to display the contrast X-ray image on Which marks derived from output of the pressure sensor are superimposed, the marks being set to positions based on the changed corresponding positions on the contrast X-ray image.

6. The X-ray diagnostic apparatus according to claim 5 , wherein the processing circuitry is configured to sequentially acquire the plurality of X-ray fluoroscopic images when the pressure sensor is being drawn out.

7. The X-ray diagnostic apparatus according to claim 5 , wherein the processing circuitry is configured to

determine positions on the contrast X-ray image that correspond to positions of the pressure sensor specified in the plurality of X-ray fluoroscopic images, and

cause the display to display the contrast X-ray image in which each position of a blood vessel is color-coded with different colors corresponding to values of an indicator relating to blood flow derived from output of the pressure sensor collected at a time of the plurality of X- ray fluoroscopic images acquisition.

8. The X-ray diagnostic apparatus according to claim 5 , wherein the user interface includes a vascular core line from a coronary tree on the contrast X-ray image, and the processing circuitry is configured to accept a sliding operation on the vascular core line to change the determined corresponding positions on the contrast X-ray image.

9. The X-ray diagnostic apparatus according to claim 5 , wherein the processing circuitry is configured to cause the display to display information relating to necessity of treatment on the contrast X-ray image.

10. An image processing method comprising:

determining, by processing circuitry, a position of a pressure sensor that is inserted into a subject from each of a plurality of X-ray fluoroscopic images acquired sequentially, and determining, positions on a contrast X-ray image of the subject that correspond to the determined positions of the pressure sensor;

accepting, by the processing circuitry, an operation to change the determined corresponding positions on the contrast X-ray image via a user interface on the contrast X-ray image displayed on a display; and

causing, by the processing circuitry, the display to display the contrast X-ray image on which marks derived from output of the pressure sensor are superimposed, the marks being set to positions based on the changed corresponding positions on the contrast X-ray image.

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

determining positions on the contrast X-ray image that correspond to positions of the pressure sensor specified in the plurality of X-ray fluoroscopic images; and

causing the display to display the contrast X-ray image in which each position of a blood vessel is color-coded with different colors corresponding to values of an indicator relating to blood flow derived from output of the pressure sensor collected at a time of the plurality of X-ray fluoroscopic images acquisition.

12. The image processing method according to claim 10 , wherein

the user interface includes a vascular core line from a coronary tree on the contrast X- ray image, and

the image processing method further comprising:

accepting a sliding operation on the vascular core line to change the determined corresponding positions on the contrast X-ray image.

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

causing the display to display information relating to necessity of treatment on the contrast X-ray image.
