【Abstract】 In this paper a hybrid bioheat conduction model is provided by means of a study of bioheat conduction mechanism and equations.Focusing on the tissue with blood vessels,a bioheat conduction computation model has been developed for conditions of treatment with ultrasound highly focused.By using the finite element method the 3 D transient temperature field was analyzed.At the same time,simulation results of the tissue lesion volume according to Sapareto Deway method were given.更多还原
