Solution Overview

Problem

In mammography apparatuses, adjusting the irradiation field according to the size of the compression plate can result in inconsistent radiographic image sizes, making it difficult to project images accurately when the compression plate sizes differ.

Innovation Solution

An information processing device that acquires projection surface size information of the compression member, generates a projection image of corresponding size, and controls an image projection unit to project the image onto the compression member's surface, ensuring accurate image alignment regardless of compression plate size.

AI summary

An information processing device including at least one processor, wherein the processor is configured to: acquire projection surface size information indicating a size of a projection surface of a compression member in a mammography apparatus that irradiates a breast compressed by the compression member with radiation to capture a radiographic image; generate a projection image having a size corresponding to the projection surface size information; and perform control to direct an image projection unit, which projects the projection image onto the projection surface of the compression member, to project the projection image onto the projection surface.
