An ultrasonic array probe is fixed to a rotational shaft at a predetermined angle, and thus a mechanical structure is made simple. An ultrasonic beam is electronically controlled so that an ultrasonic transmission/reception direction may become substantially perpendicular to the surface of the mamma. Thereby, data on the entire mamma including a C' region can be collected only by the rotation of the probe. In addition, a membrane which is interposed between the probe and the mamma is formed to have a mesh-like structure, thereby reducing multiple reflection. Moreover, a B mode image and a C mode image are displayed at the same time, and thereby an accurate diagnosis can be performed in a short time.
