Learning data creation apparatus, method, program, and medical image recognition apparatus

A learning data creation method for creating learning data for machine learning and sequentially storing the created learning data in a memory by a first processor,

• wherein each processing of the first processor includes
• acquiring a first medical image from a modality,
• detecting a target region from the acquired first medical image,
• detecting a reference region having a known size from the acquired first medical image,
• determining whether or not the detected target region and the reference region are in contact,
• measuring a size of the target region based on the size of the reference region in a case where a contact between the target region and the reference region is determined, and
• storing, in the memory, as the learning data, a pair of the first medical image including the target region of which the size is measured, and the measured size of the target region.

A non-transitory, computer-readable tangible recording medium which records thereon computer instructions that, when read by a computer, cause the computer to implement:

• a function of acquiring a first medical image from a modality;
• a function of detecting a target region from the acquired first medical image;
• a function of detecting a reference region having a known size from the acquired first medical image;
• a function of determining whether or not the detected target region and the reference region are in contact;
• a function of measuring a size of the target region based on the size of the reference region in a case where a contact between the target region and the reference region is determined;
• and
• a function of storing, in the memory, as learning data for machine learning, a pair of the first medical image including the target region of which the size is measured, and the measured size of the target region.
