Abstract
In an ultrasonic CT device for breast examination, unevenness of an ultrasonic image due to a distribution of inclination angles of a breast is reduced. The distribution of the inclination angles of a surface of a subject in a contour of the subject is obtained from a tomographic image, and a signal level of a reception signal or a pixel value of the tomographic image is corrected using the distribution of the inclination angles.
