Abstract: A medical system can include a light source configured to generate excitation light; and a processor including a memory, the processor: controlling energy supplied to an energy device, the light source generating the excitation light to generate fluorescence from the living body tissue heat treated by the energy device; generating a fluorescence image based on an image pickup signal obtained by imaging the living body tissue; and generating a control signal that restricts energy supply to the energy device and output the control signal to the energy control apparatus when a pixel value of at least one pixel in the fluorescence image exceeds a first threshold value.

Abstract: A heat invasion observation apparatus that observes a heat invasion to a biological tissue, the heat invasion observation apparatus includes a fluorescence image generation circuit configured to obtain an image pickup signal generated by picking up an image of fluorescence generated from a heat invasion area in the biological tissue irradiated with exciting light for exciting a substance contained in the heat invasion area, and generate fluorescence image data based on the obtained image pickup signal. The substance contained in the heat invasion area is a substance generated when the biological tissue is thermally processed.

Abstract: An assistant device includes a processor configured to: generate a first image including one or more characteristic regions requiring excision by a surgical operator; generate a second image including one or more cauterized regions cauterized by an energy device; generate information regarding presence or absence of a first region that is included in the characteristic regions and that is not included in the cauterized region based on the first image and the second image; and output information indicating the presence of the characteristic regions that requires to be cauterized when the first region is present.
