TENDENCY DISCRIMINATION DEVICE, TASK EXECUTION ASSISTING DEVICE, TENDENCY DISCRIMINATION COMPUTER PROGRAM, AND TASK EXECUTION ASSISTING COMPUTER PROGRAM

摘要

A tendency discrimination device includes a discriminator to objectively discriminate a tendency of a person to be tested, based on brain information obtained by magnetic resonance imaging (MRI). In the generation of the discriminator, a gray matter volume and a diffusion anisotropy degree are calculated for a frontal pole of each of multiple test subjects as a region of interest, and machine learning is performed on the relationship of the information obtained by classifying results of a test for discriminating the tendencies of the multiple test subjects, to gray matter volumes and diffusion anisotropy degrees obtained by MRI for each of the multiple test subjects.

主权项

1. A tendency discrimination device comprising:
a storage unit for storing data of an anatomical image and a diffusion weighted image, obtained by magnetic resonance imaging for each of subjects, and classification information in association with each of a plurality of the subjects, obtained by classifying results of a test for judging a tendency of each of the subjects; and an arithmetic unit for executing a process for tendency discrimination, based on the information stored in the storage unit, wherein the arithmetic unit calculates a gray matter volume and a diffusion anisotropy degree for a predetermined brain region of each of the plurality of subjects as a region of interest, based on the anatomical image and the diffusion weighted image, and generates a discriminator by a machine learning of relationship of the classification information to the gray matter volume and the diffusion anisotropy degree, and wherein the discriminator outputs a tendency index of a person to be tested.
