| Research Abstract |
The results reveal that it should be possible to identify the biological tissue being irradiated by analyzing the laser-induced sound characteristics, which differ according to the kind and the state of the tissue. This study found that laser-induced sound is generated by the evaporation of water in the biological tissue using the high-speed video camera. The laser irradiation parameters could also be controlled based on the laser-induced sound, making it possible to adjust the incision volume. If this laser percussion technique was realized in practice, it may allow even relatively inexperienced doctors to perform laser treatment safely and reliably.
