Diagnosis support system, information processing method, and program

An information processing method, comprising:

• acquiring first tomographic image data and second tomographic image data stacking a plurality of cross-sectional images;
• performing subtract processing between the first tomographic image data and the second tomographic image data to generate subtraction image data;
• performing projection processing on the subtracted image data in a projection direction to generate projection image data of the subtracted image data, wherein the projection direction is substantially perpendicular to the-a stacking direction of the plurality of cross-sectional images;
• and
• displaying a projection image based on the projection image data,
• wherein in a case where a coordinate on the projection image is designated, displaying the projection image and a first cross-sectional image of the first tomographic image data corresponding to the coordinate and a second cross-sectional image of the second tomographic image data corresponding to the coordinate.

A non-transitory computer-readable recording medium storing a program causing a computer to execute an information processing method, the method comprising:

• acquiring first tomographic image data and second tomographic image data stacking a plurality of cross-sectional images;
• perform subtract processing between the first tomographic image data and the second tomographic image data to generate subtraction image data;
• performing projection processing on the subtracted image data in a projection direction to generate projection image data of the subtracted image data, wherein the projection direction is substantially perpendicular to the a stacking direction of the plurality of cross-sectional images;
• and
• displaying a projection image based on the projection image data,
• wherein in a case where a coordinate on the projection image is designated, displaying the projection image and a first cross-sectional image of the first tomographic image data corresponding to the coordinate and a second cross-sectional image of the second tomographic image data corresponding to the coordinate.
