Abstract

Provided is a learning device that trains a machine learning model. The learning device includes a processor and a memory, in which the processor generates a plurality of pseudo images, which are pseudo images of a human body generated based on a human body model composed of three-dimensional computer graphics data and imitate an examination subject in a state of being positioned with respect to a medical imaging apparatus, for each combination of an imaging part and an imaging direction, and trains the machine learning model using a plurality of teacher data composed of the generated pseudo image and correct answer data of the combination.
