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.

First claim

What is claimed is:

1. An image processing apparatus comprising:
processing circuitry configured to
determine a plurality of locations of a pressure sensor that is inserted into a subject from each of a plurality of X-ray fluoroscopic images acquired sequentially,
determine a plurality of reference positions on a contrast X-ray image of the subject that correspond to the plurality of locations of the pressure sensor, and
cause a display to display the contrast X-ray image indicating one of a plurality of values derived from output of the pressure sensor, and to display a chart based on the plurality of values,

wherein the plurality of values are values related to blood flow.

2. The image processing apparatus according to claim 1 , further comprising:
an input interface configured to accept an operation to input a position where the displayed value was obtained.

3. The image processing apparatus according to claim 1 , wherein, when an instruction to indicate a value on the contrast X-ray image is received from a user, the processing circuitry is configured to cause the display to display the contrast X-ray image indicating one of the plurality of values, and to display the chart and a fluoroscopic image acquired after the plurality of X-ray fluoroscopic images.

4. The image processing apparatus according to claim 3 , wherein the chart indicating the plurality of values is generated from output of the pressure sensor during acquisition of the plurality of X-ray fluoroscopic images.

5. The image processing apparatus according to claim 1 , wherein the processing circuitry is configured to superimpose a line segment at a position corresponding to the displayed value in the chart based on the plurality of values.

6. The image processing apparatus according to claim 1 , wherein the processing circuitry is configured to cause the display to display the contrast X-ray image on which the displayed value is indicated at a position near the position where the displayed value was obtained in the contrast X-ray image.

7. The image processing apparatus according to claim 1 , wherein the processing circuitry is configured to determine the plurality of reference positions on a contrast X-ray image based on a front end of the pressure sensor drawn on the plurality of X-ray fluoroscopic images.

8. The image processing apparatus according to claim 1 , wherein the processing circuitry is further configured to
collect the plurality of X-ray fluoroscopic images acquired by an X-ray diagnostic apparatus,
collect the plurality of values measured by a measuring device, and
associate acquisition phases of the plurality of X-ray fluoroscopic images with measurement phases of the plurality of values.

9. 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 plurality of locations of a pressure sensor that is inserted into the subject from each of the plurality of X-ray fluoroscopic images,
determine a plurality of reference positions on the contrast X-ray image of the subject that correspond to the plurality of locations of the pressure sensor, and
cause a display to display the contrast X-ray image indicating one of a plurality of values derived from output of the pressure sensor, and to display a chart based on the plurality of values,

wherein the plurality of values are values related to blood flow.

10. The X-ray diagnostic apparatus according to claim 9 , wherein the processing circuitry is configured to acquire the plurality of X-ray fluoroscopic images while the pressure sensor is drawn out.

11. An image processing method comprising:
determining a plurality of locations of a pressure sensor that is inserted into a subject from each of a plurality of X-ray fluoroscopic images acquired sequentially;
determining a plurality of reference positions on a contrast X-ray image of the subject that correspond to the plurality of locations of the pressure sensor; and
causing a display to display the contrast X-ray image indicating one of a plurality of values derived from output of the pressure sensor, and to display a chart based on the plurality of values,
wherein the plurality of values are values related to blood flow.
