Study into penetration speed during laser cutting of brain tissues

The applications of CO2 continuous-wave lasers in neurosurgery have become important in recent years. Theoretical considerations of laser applicabilit y in medicine are subsequently confirmed experimentally. To obtain precisio n operation in the laser cutting process, further theoretical developments and experimental studies need to be conducted. Consequently, in the present study, the heat transfer mechanism taking place during laser-tissue intera ction is introduced using Fourier theory. The results obtained from the the oretical model are compared with the experimental results. In. connection w ith this, an experiment is designed to measure the penetration speed during the laser cutting process. The measurement is carried out wing an optical method. It is found that both results for the penetration speed obtained fr om the theory and experiment are in a good agreement.
