1. An ultrasound system comprising:
an ultrasound probe; and
a first processor,
wherein the first processor
generates, from a reception signal obtained by performing transmission and reception of an ultrasound beam with respect to a breast of a subject by using the ultrasound probe, an ultrasound image including a second region of interest of the breast of the subject corresponding to a first region of interest of the breast of the subject included in a radiation image,
specifies the second region of interest included in the ultrasound image, and
determines whether or not the first region of interest included in the radiation image and the second region of interest are identical to each other,
wherein the first processor has a first determination model that has learned, using learning ultrasound images of the breast of the subject as first teacher data, a relationship between the learning ultrasound image and a region of interest included in the learning ultrasound image for a plurality of pieces of the first teacher data, and
the first determination model uses the ultrasound image as an input, and specifies the second region of interest included in the ultrasound image.
