Medical image processing apparatus, medical image processing method, machine learning system, and program

A medical image processing method to be performed by a medical image processing apparatus, the medical image processing method comprising:

• a step of obtaining a medical image;
• a step of performing additional training for a first computer-aided diagnosis device by using a trainer on a basis of the obtained medical image;
• a step of comparing a second computer-aided diagnosis device obtained by the additional training using the trainer with the first computer-aided diagnosis device and evaluating whether learning difference information about the additional training contributes to improvement of performance of the first computer-aided diagnosis device;
• a step of determining, on a basis of a result of evaluation obtained in the evaluating, whether the learning difference information is to be communicated;
• and
• a step of outputting, from a communication unit, the learning difference information in accordance with a result of determination obtained in the determining.

A storage medium that is a non-transitory computer-readable storage medium and that, in a case where a command stored in the storage medium is read by a computer, causes the computer to execute:

• a function of a trainer performing additional training for a first computer-aided diagnosis device on a basis of an input medical image;
• a function of comparing a second computer-aided diagnosis device obtained by the additional training using the trainer with the first computer-aided diagnosis device and evaluating whether learning difference information about the additional training contributes to improvement of performance of the first computer-aided diagnosis device;
• a function of determining, on a basis of a result of evaluation obtained in the evaluating, whether the learning difference information is to be communicated;
• and
• a function of outputting, from a communication unit, the learning difference information in accordance with a result of determination obtained in the determining.
