The sectional form of the human femur is measured via an ultrasonic pulse echo method. After the wave velocity through the thigh is set at 1500 m/s, the ultrasonic wave is emitted toward the femur using a normal probe attached to the thigh. The echo waveform reflected from the outside and inside of the femur is measured, and the sectional form of the femur presented in two dimensions is compared with that of the X-ray. Consequently, the wave velocities of the femur and the muscle are determined as 3300 m/s and 1560 m/s, respectively. Next, the sectional form of the femur modified by these values, obtained via the ultrasonic method, is compared with that of the X-ray CT. It is found that both results agree approximately. Thus, the ultrasonic method is applicable for the proposed purpose.
