Ultrasonic apparatus and for precisely locating cavitations within jawbones and the like

摘要

A method and apparatus detects cavitation in the jawbone of human. The apparatus generates an ultrasonic pulse and passes the pulse through the jawbone of a human. The pulse is detected by an ultrasonic receiving unit. Attenuations in the amplitude of the pulse are detected and displayed on a color monitor. The color monitor allows the detection of cavitations by interpreting color codes in a 4×4 matrix displayed on the monitor.
