Abstract
According to an embodiment, a medical image processing device includes processing circuitry. The processing circuitry acquires a medical image obtained by imaging at least an artery. The processing circuitry detects a branch point of the artery on the basis of the medical image. The processing circuitry identifies a dominated region affected by the artery on a downstream side of the branch point in the medical image. The processing circuitry causes a display to display the dominated region.
Claims10
A medical image processing device comprising:
- processing circuitry configured to
- acquire a medical image obtained by imaging at least an artery;
- detect a branch point of the artery on the basis of the medical image;
- identify a dominated region of the artery on a downstream side of the branch point in the medical image;
- cause a display to display the dominated region;
- derive a time density curve on the basis of a change over time in a luminance value of each pixel of the medical image;
- generate a contrast delay time map in which a delay period of time of a contrast medium injected into the artery is set as a pixel value on the basis of the time density curve;
- and
- identify a dominated region of the artery on the contrast delay time map using a region expansion method.
