Medical image processing apparatus and medical image processing method

摘要

A medical image processing apparatus includes a selection unit which selects a combination of images acquired in substantially equal time phases in a cycle from a first image group including a plurality of first images acquired at different time points in a first period by imaging an organ whose shape cyclically varies and a second image group including a plurality of second images acquired at different time points in a second period different from the first period by imaging the organ based on a characteristics value indicative of characteristics of the shape of the organ measured from the first and second image groups, and a generation unit which generates combination information indicative of the combination selected by the selection unit.

1. A medical image processing apparatus comprising:
a control unit which selects a combination of a first image, which is one of first images, the first images being acquired with respect to a slice at different time points in a first period by imaging an organ whose shape cyclically varies, and a second image, which is one of second images, the second images being acquired with respect to the slice at different time points in a second period different from the first period by imaging the organ, based on a characteristics value indicative of characteristics of a shape of the organ measured from the first and second images, wherein selecting the combination of the first image and the second image comprises selecting the combination of the first image and the second image acquired in a substantially same time phase in a cycle (1) by specifying a shape on an image of the organ from the image data and (2) calculating an expansion coefficient of the organ based on the specified shape such that an expansion coefficient of the organ in the first image substantially coincides with that of the second image, and a direction when the shape of the organ varies, which is an expanding direction or a contracting direction, in the first image coincides with that of the second image; and the control unit further generates combination information indicative of the selected combination.
