摘要

A discriminator includes 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, using a plurality of data sets of a first image obtained by capturing an image of a subject that has developed a disease and an image data of a disease region in the first image, such that information indicating the disease region is output from a first learning unit in a case in which the first image is input to the common learning unit. In addition, the discriminator is trained, using a plurality of data sets of an image set obtained by registration between the first image and a second image whose type is different from the type of the first image, such that an estimated image of the second image is output from an output unit of a second learning unit.

FIG. 8 is a diagram illustrating a displayed CT image of the brain.

FIG. 9 is a flowchart illustrating a process performed during learning.

FIG. 10 is a flowchart illustrating a process performed during the discrimination of an infarction region.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter, a first embodiment of the present disclosure will be described with reference to the drawings. FIG. 1 is a hardware configuration diagram illustrating the outline of a diagnosis support system to which a learning apparatus for training a discriminator, a discriminator, and a disease region discrimination apparatus according to an embodiment of the present disclosure are applied. As illustrated in FIG. 1, in the diagnosis support system, a disease region discrimination apparatus 1, a three-dimensional imaging apparatus 2, and an image storage server 3 according to this embodiment are connected so as to communicate with each other through a network 4. In addition, the disease region discrimination apparatus 1 includes the learning apparatus and the discriminator according to this embodiment.
