摘要
To avoid carbonization of tissues surrounding to the heating part of laser fiber during treating tumor by laser-induced interstitial thermotherapy (LITT), a new method using ultra-low temperature fluid was proposed for cooling laser fiber and tissues in the vicinity of laser fiber in this study. To test its feasibility, the corresponding bioheat transfer process applying this cooling method during LITT was studied through extensive numerical simulations. The results indicate that the cooling method by ultra-low temperature fluid can prevent carbonization of tissues resulted by local high temperature, significantly enlarge the effective heating area and thus actualize highly efficient thermal coagulation to tumor tissues.
