Medical image processing device, operation method of medical image processing device, and operation program of medical image processing device

An operation method of a medical image processing device, comprising:

• acquiring a medical image;
• deriving indirect finding information related to an indirect finding that represents at least one feature of a shape or a property of peripheral tissue of a lesion associated with an occurrence of the lesion by analyzing the medical image using a first machine learning model;
• deriving provisional lesion presence probability information that indicates a provisional presence probability of the lesion, which represents at least one feature of a shape or a property of the lesion, by analyzing the medical image using a second machine learning model;
• and
• deriving lesion presence probability information that indicates a presence probability of the lesion based on the indirect finding information and the provisional lesion presence probability information using a third machine learning model.

A non-transitory computer-readable storage medium storing an operation program of a medical image processing device for causing a computer to execute a process comprising:

• acquiring a medical image;
• deriving indirect finding information related to an indirect finding that represents at least one feature of a shape or a property of peripheral tissue of a lesion associated with an occurrence of the lesion by analyzing the medical image using a first machine learning model;
• deriving provisional lesion presence probability information that indicates a provisional presence probability of the lesion, which represents at least one feature of a shape or a property of the lesion, by analyzing the medical image using a second machine learning model;
• and
• deriving lesion presence probability information that indicates a presence probability of the lesion based on the indirect finding information and the provisional lesion presence probability information using a third machine learning model.
