Image diagnosis support device

A CPU of a console includes a first acquisition unit, a second acquisition unit, a specifying unit, and an extraction unit. The first acquisition unit acquires designation information of a measurement target part of a bone density of a subject. The second acquisition unit acquires an optical image obtained by imaging the subject facing radiography with a camera. The specifying unit specifies a region of the measurement target part in the optical image based on the designation information. The extraction unit extracts a region in a radiation image corresponding to the region of the measurement target part as a measurement region of the bone density based on correspondence relationship information between pixels of the radiation image and pixels of the optical image.
