Publication number: 20230410298Abstract: The system includes a memory that stores a trained model, and a processor. The processor acquires a pre-treatment image in which at least one energy device and at least one biological tissue are imaged, and a state before application of energy is imaged. The processor estimates an estimated heat diffusion region from the pre-treatment image and information regarding an energy supply amount by processing based on a trained model stored in the memory. The processor superimposes the estimated heat diffusion region on a captured image of the camera and displays the captured image with the superimposed estimated heat diffusion region.Type: ApplicationFiled: August 24, 2023Publication date: December 21, 2023Applicant: OLYMPUS CORPORATIONInventors: Masahiro FUJII, Takeshi ARAI
