<p>An ultrasonic probe that is pressed to a subject to obtain an elasticity image. The probe has a contact surface used for contact with the subject and is orthogonal to the direction of the pressing and has an automatic pressing means or a manual pressing means. The automatic pressing means is adapted for moving the contact surface in a pressing direction to press a to-be-imaged portion of the subject at a predetermined pressing force, and manual pressing means presses the portion by a manual force. Using the ultrasonic prove having the automatic pressing means or the manual pressing means enables a pressing stage to be automatically or manually moved in a vertical fixed direction at a desired speed, and as a result elasticity image data with high image quality can be obtained at a desired time. Further, repeatability of pressing operation can be retained, which enables a problem of the quality of an elasticity image being dependent on an inspector to be eliminated.</p> |
