Abstract

A medical support method includes acquiring a first optical image and an ultrasound image in a case in which an ultrasound endoscope is connected to an image processing device, acquiring a second optical image in a case in which an optical endoscope is connected to the image processing device, outputting the first optical image and the ultrasound image to a display device in a case in which the ultrasound endoscope is connected to the image processing device; and outputting the second optical image and a first recognition result, which is obtained by causing a trained model for an optical image to recognize a first feature region shown in the second optical image, to the display device in a case in which the optical endoscope is connected to the image processing device.
