Determination of energy flux density of radial shock wave

Abstract

As a new medical technology, radial shock wave therapy has unique advantages in orthopedics, sports medicine and other medical fields. However, an unified index is needed to evaluate the intensity of clinical treatment of radial shock wave therapy. Based on the principle of radial shock wave generation, the energy flow density was advanced as an index for evaluating the intensity of clinical treatment. High precision underwater dynamic pressure measurement system was established to measure the pressure waveform. Then the laser Doppler vibration measurement was used to measure the vibration wave of the wave source accurately. The correctness of the pressure waveform measured through the experimental system is proved by comparing the two kinds of waveform. Finally, the energy flow density was calculated according to the measured pressure waveform, which is helpful to effectively reduce the blindness because of simultaneous adjustment of multiple parameters, and it was advanced as an index for evaluating the intensity of shock wave, which has positive guiding significance for its clinical application.
