Title: Ultrasonic probe
Inventor: WATANABE TORU
IPC: A61B8/00
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To improve focusing of a resonator in the longitudinal direction of an ultrasonic probe. SOLUTION: A number of grooves 70 are formed on the surface of a packing material 54 abutting on a piezo-electric resonator 52. The density of the opening area of the grooves 70 on the surface becomes higher toward the center in the longitudinal direction. Accordingly, the damping effect of the packing material 54 grows weak toward the center, the absorbing effect of ultrasonic waves also growing weak. As a result, the nearer to the center, the more acoustic power is turned toward a subject. On the other hand, the nearer to the end, the more ultrasonic waves are absorbed in the packing material 54. Therefore, side lobes of ultrasonic beams are reduced, the power of main beams increased, so that the beam width of the resonator in the longitudinal direction is narrowed.
