Abstract :

In this paper, considering the damage equation, tissue heat transfer equations and also the Thermal damage time (TDT) of tissue at a specific temperature, the concept of selective photothermolysis has been studied in an organized and comprehensive way much better, more effective and closer clinical results to what is actually happening in reality. Because in laser-tissue thermal interactions therapies, the thermal relaxation time (TRT) of tissue and the choice of laser pulse width related to that are important parameters. On the other hand, the effect of the damage function and its related parameters on laser-tissue thermal interactions cannot be ignored, because they interfere with the analysis of the effectiveness of laser-tissue thermal reactions. Therefore, while examining the theory of topics related to selective photothermolysis, and clinical conditions affecting laser-tissue thermal interactions that lead to the phenomenon of selective photothermolysis have been investigated.
