APPARATUS, METHOD, AND PROGRAM FOR TRAINING DISCRIMINATOR DISCRIMINATING DISEASE REGION, DISCRIMINATOR DISCRIMINATING DISEASE REGION, DISEASE REGION DISCRIMINATION APPARATUS, AND DISEASE REGION DISCRIMINATION PROGRAM

摘要

To allow highly accurate discrimination of a disease region by the use of limited amounts of data, even in the case of an image in which it is difficult to prepare large amounts of data indicating a correct disease region, in an apparatus, method, and program for training a discriminator discriminating a disease region, a discriminator discriminating a disease region, a disease region discrimination apparatus, and a disease region discrimination program.SOLUTION: A discriminator comprises: a common learning unit; and a plurality of learning units that are connected to an output unit of the common learning unit. The discriminator is trained such that when a medical image is input to the common learning unit using a plurality of datasets of the medical image and a correct mask of a first disease region, information indicating the first disease region is output from a first learning unit. The discriminator is trained such that when a medical image is input to the common learning unit using a plurality of datasets of the medical image and a correct mask of a second disease region having at least one of medical and anatomical cause-and-effect relations with the first disease, information indicating the second disease region is output from a second learning unit.SELECTED DRAWING: Figure 2
