PROBLEM TO BE SOLVED: To adjust the abutting posture of a probe in the case of pressurizing a living body by the probe and measuring the displacement of tissue before and after pressurization. SOLUTION: The internal unit 14 of the probe 10 includes a vibrator unit 16, a vertical drive unit 18, a Z axis positioning unit 20, an X axis positioning unit 22, and a Y axis positioning unit 23, etc. Cyclic back and forth movements are given to the vibrator unit 16 by the vertical drive unit 18, and the Z axis positioning unit 20 determines the origin in a Z axis direction of the vertical drive unit 18. The directions around an X axis and around a Y axis of the vibrator unit 16 are adjusted by the X axis positioning unit 22 and the Y axis positioning unit 23. COPYRIGHT: (C)2009,JPO&INPIT
