Medical image processing device, oct device, and storage medium storing medical image processing program

An OCT device that captures image data of a living tissue by receiving interference light between reference light and reflected light of measurement light emitted onto the living tissue, the image data being image data of a three-dimensional image formed by arranging, in X-Y directions which are two-dimensional directions intersecting a Z direction, a plurality of Z-direction images each extending in the Z direction which is a depth direction of the living tissue, the OCT device comprising:

• a control unit that is configured to execute:
• an image data acquisition step of acquiring first image data and second image data that were captured on a living tissue of a same subject at different times, at least some of imaging positions for the first and second image data overlapping with each other;
• a correlation acquisition step of acquiring, for positions in the X-Y directions, a plurality of correlations between the plurality of Z-directions images in the first image data and the plurality of Z-direction images in the second image data, each of the correlations being acquired for a pair of one of the plurality of Z-direction images in the first image data and a corresponding one of the plurality of Z-direction images in the second image data both of which have a same imaging position;
• and
• a correlation output step of processing and outputting the plurality of correlations for the positions in the X-Y directions.

A non-transitory, computer readable, storage medium storing a medical image processing program for a medical image processing device that processes image data of a living tissue, the image data being image data of a three-dimensional image formed by arranging, in X-Y directions which are two-dimensional directions intersecting a Z direction, a plurality of Z-direction images each extending in the Z direction which is a depth direction of the living tissue, the program, when executed by a control unit of the medical image processing device, causing the control unit to execute:

• an image data acquisition step of acquiring first image data and second image data that were captured on a living tissue of a same subject at different times, at least some of imaging positions for the first and second image data overlapping with each other;
• a correlation acquisition step of acquiring, for positions in the X-Y directions, a plurality of correlations between the plurality of Z-directions images in the first image data and the plurality of Z-direction images in the second image data, each of the correlations being acquired for a pair of one of the plurality of Z-direction images in the first image data and a corresponding one of the plurality of Z-direction images in the second image data both of which have a same imaging position;
• and
• a correlation output step of processing and outputting the plurality of correlations for the positions in the X-Y directions.
