A finite element approach for Bubble Formation during Laser-Induced Thermotherapy (LIT) of breast Cancer Tumor

Résumé

Laser induced interstitial thermotherapy LITT is a minimally invasive process intended for precise aiming at breast cancer tumors. Based on the principle of controlled and localized heat ablation. We developed a theoretical computational model emphasizes the role and importance of water present within the tissue.  During LITT, vaporization of water taken into account to encounter energy changes. A finite element method was used to probe, the effects of vaporization and development of froths using a bubble formation model. We investigated bubble formation and vaporization by studying the effects of laser power, bubble size and radius effects. The generated results demonstrated tissue water density variations relative to heat influx and pertaining to both tissue heat evolution and its reaction to vaporization processes.
