Breast - A61B: DIAGNOSIS; SURGERY; IDENTIFICATION (usefulness limited to only animals A61D) - G06T: IMAGE DATA PROCESSING OR GENERATION, IN GENERAL ## Abstract An information processing device including at least one processor, wherein the processor is configured to control an image projection unit which projects a projection image onto a first projection surface of a compression member disposed between a radiation source and a radiation detector in a mammography apparatus that irradiates a breast compressed by the compression member with radiation to capture a radiographic image such that at least one of first information or second information is switchably projected onto the first projection surface. ## Claims ### Claim 1 An information processing device comprising at least one processor, wherein the processor is configured to control an image projection unit which projects a projection image onto a first projection surface of a compression member disposed between a radiation source and a radiation detector in a mammography apparatus that irradiates a breast compressed by the compression member with radiation to capture a radiographic image such that at least one of first information or second information is switchably projected onto the first projection surface. ### Claim 2 (depends on 1) The information processing device according to claim 1, wherein the processor is configured to: receive a selection instruction to select the first information and the second information projected onto the first projection surface; and switch the first information and the second information projected onto the first projection surface on the basis of the selection instruction. ### Claim 3 (depends on 1) The information processing device according to claim 1, wherein the processor is configured to switch the first information and the second information projected onto the first projection surface for a period for which the breast is positioned between the radiation source and the radiation detector and a period after the positioning is completed. ### Claim 4 (depends on 1) The information processing device according to claim 1, wherein the processor is configured to switch the first information and the second information projected onto the first projection surface according to a compression pressure of the breast by the compression member. ### Claim 5 (depends on 1) The information processing device according to claim 1, wherein the processor is configured to switch the first information and the second information projected onto the first projection surface according to a thickness of the breast in a compression direction in which the breast is compressed. ### Claim 6 (depends on 1) The information processing device according to claim 1, wherein the processor is configured to: acquire projection surface size information indicating a size of the first projection surface; and change a relative position of the first information and the second information projected onto the first projection surface depending on the size of the first projection surface indicated by the projection surface size information. ### Claim 7 (depends on 1) The information processing device according to claim 1, wherein the processor is configured to: acquire projection surface size information indicating a size of the first projection surface; perform control to project both the first information and the second information onto the first projection surface in a case in which the projection surface size information indicates that the first projection surface is equal to or larger than a predetermined size; and perform control to project either the first information or the second information onto the first projection surface in a case in which the projection surface size information indicates that the first projection surface is smaller than the predetermined size. ### Claim 8 (depends on 1) The information processing device according to claim 1, wherein: the image projection unit projects an image onto a second projection surface different from the first projection surface of the compression member in addition to the first projection surface, and the processor is configured to control the image projection unit such that the first information and the second information are projected onto different projection surfaces of the first and second projection surfaces. ### Claim 9 (depends on 1) The information processing device according to claim 1, wherein the processor is configured to perform control to project the first information and the second information in different display aspects. ### Claim 10 (depends on 1) The information processing device according to claim 1, wherein: the first information is guide information that serves as a guide in a case in which the breast is positioned, and the second information is imaging information including at least one of information indicating a compression pressure of the breast by the compression member, information indicating a thickness of the breast in a compression direction in which the breast is compressed, subject information indicating a subject pertaining to the breast as an object to be imaged, radiographer information indicating a radiographer who performs imaging, date information indicating a date of imaging, or angle information indicating an angle at which an image of the breast is captured. ### Claim 11 An information processing method comprising: controlling an image projection unit which projects a projection image onto a first projection surface of a compression member disposed between a radiation source and a radiation detector in a mammography apparatus that irradiates a breast compressed by the compression member with radiation to capture a radiographic image such that at least one of first information or second information is switchably projected onto the first projection surface. ### Claim 12 A non-transitory computer-readable storage medium storing an information processing program that causes a computer to perform a process of: controlling an image projection unit which projects a projection image onto a first projection surface of a compression member disposed between a radiation source and a radiation detector in a mammography apparatus that irradiates a breast compressed by the compression member with radiation to capture a radiographic image such that at least one of first information or second information is switchably projected onto the first projection surface.
