Abstract
From a plurality of medical images in time phases, a target site is extracted from at least one medical image, a reference point is set on each of a target-site side, and a periphery side of the target site which are on across from each other over an outline of the extracted target site, and movement information for the reference points is calculated.

A medical image processing apparatus comprising:
- an acquisition unit configured to acquire a plurality of medical images obtained by capturing a target site at times different to each other;
- a registration unit configured to perform registration process on a periphery side of the target site between the plurality of medical images that are set to a first condition, and perform registration process on a target-site side of the target site between the plurality of medical images that are set to a second condition different from the first condition;
- and
- a calculation unit configured to calculate, based on a result of the registration process on the periphery side of the target site and a result of the registration process on the target-site side of the target site, slippage on each of a plurality of points being on an outline of the target site.
