DIAGNOSTIC IMAGING DEVICE, DIAGNOSTIC IMAGING METHOD, DIAGNOSTIC IMAGING PROGRAM, AND LEARNED MODEL

摘要

Provided are a diagnostic imaging device, a diagnostic imaging method, a diagnostic imaging program and a learned model, which can improve the diagnostic accuracy for esophagus cancer in esophagogastroduodenoscopy. This diagnostic imaging device comprises: an endoscopic image acquisition unit for acquiring an endoscopic moving image showing the esophagus of a person being tested; an estimation unit for estimating the location of esophagus cancer that is present in the acquired endoscopic moving image, using a convolutional neural network that has learned from esophagus cancer images as training data, the esophagus cancer images having been obtained from esophaguses affected by esophagus cancer; and a display control unit that superimposes on the endoscopic moving image an estimated location of the esophagus cancer and a certainty factor serving as an index for the probability that esophagus cancer is present at that location.
