  • Publication number: 20230306592
    Abstract: A processor of an image processing device acquires a medical image including a lesion region, and causes a determiner to perform a determination process of determining a type of a lesion on the basis of the medical image. A first determination process is a process of determining whether the type belongs to a first group including a first type classified as a first category and a second type classified as a second category or a second group including a third type classified as the second category. A second determination process is a process of determining whether the type is the first type or the second type. The processor outputs a first signal for specifying whether the type is classified as the first category or the second category on the basis of a determination result of the first determination process and a determination result of the second determination process.
