抄録

In this study, we developed the ultrasonic arthroscope, which can measure 3-dimesional position of the site of the disease, by using the 3-dimensional magnetic sensor. We measured the ultrasonic echo from articular cartilage upon which the enzyme acts. Then, wavelet transform was used to evaluate the articular cartilage. The result of this study showed that the echo amplitude is affected by enzyme processing time. And, the frequency domain from 12 to 17MHz disappeared.
