PROBLEM TO BE SOLVED: To solve issues of conventionally proposed immersion type automatic ultrasonic examination apparatus for breast cancer that a special ultrasonic probe with wide view field width is used resulting in difficulty of the ultrasonic probe hardly to be close to the body surface to be brought in parallel with the body surface causing deterioration of image quality, and not only the ultrasonic probe but also the ultrasonic examination apparatus body requires larger scale and higher price. SOLUTION: An ultrasonic probe with narrow view field width is used and shift and tilt functions are newly added to mechanical rotation and vertical movement of conventional probes. By performing feedback control using ultrasonic reflection data, it is enabled for the ultrasonic probe to be close to the body surface and brought in parallel with the body surface. By using a conventional ultrasonic probe with narrow width, costs of the ultrasonic probe and the apparatus body are suppressed to the minimum and the apparatus body is enabled to be used as a general purpose ultrasonic examination apparatus.
