Learning device, learning method, and learned model

Abstract

Provided are a learning device, a learning method, and a learned model capable of allowing an operator to ascertain what part inside a body of a subject is observed in the middle of examination by medical equipment. In a learning device, a learning method and, a learned model, an image acquisition unit acquires a medical image of an observation target part inside the body of the subject in each of a plurality of observation steps in which an observation order of the observation target part is determined, a step prediction unit outputs a prediction step predicting an observation step corresponding to the medical image from the medical image based on a learning result in each observation step, a step comparison unit compares the prediction step with a ground truth step corresponding to the prediction step in each observation step, and a learning controller makes the step prediction unit learn a relationship between the medical image and the prediction step based on a result of comparison by the step comparison unit in each observation step such that the prediction step becomes close to the ground truth step.
