Medical apparatus, medical system, control method, and computer-readable recording medium

A medical system comprising:

• an endoscope that includes an image sensor;
• a light source apparatus that includes a light source configured to apply white light and excitation light;
• and
• a control apparatus that includes a processor comprising hardware, the processor being configured to
• acquire area information that includes information on an area of interest based on input from a user, the area of interest being an organ that is adjacent to a target organ that is a target for thermal treatment,
• acquire a fluorescence image that is generated based on an imaging signal captured at a timing of application of excitation light,
• extracts a thermally denatured area based on the fluorescence image, and
• generate thermal denaturation information based on the area of interest and the thermally denatured area.

A control method of controlling a medical apparatus, the control method comprising:

• acquiring area information that includes information on an area of interest based on input from a user, the area of interest being an organ that is adjacent to a target organ that is a target for thermal treatment;
• acquiring a fluorescence image that is generated based on an imaging signal captured at a timing of application of excitation light;
• extracting a thermally denatured area based on the fluorescence image;
• and
• generating thermal denaturation information based on the area of interest and the thermally denatured area.

A non-transitory computer-readable recording medium with an executable program stored thereon, the program causing a processor of a medical device to execute:

• acquiring area information that includes information on an area of interest based on input from a user, the area of interest being an organ that is adjacent to a target organ that is a target for thermal treatment;
• acquiring a fluorescence image that is generated based on an imaging signal that is captured at a timing of application of excitation light;
• extracting a thermally denatured area based on the fluorescence image;
• and
• generating thermal denaturation information based on the area of interest and the thermally denatured area.
