Abstract
Abstract: When blood vessel exists in the tumor tissue, and its boundary portion close to the vessel will be strongly influenced by the cooling effect of the blood vessel. This influence will lead to the incomplete cancer treatment. To study the influence of blood flow on heating towards the above situation, concave spherical transducer was used as the heat source, and sound intensity distribution was obtained by Rayleigh integral. Pennes equation was solved with finite difference method, then the dose distribution was calculated to determine the thermal damage degree of tissue using quantitative relationship between the heating time and temperature. The simulation results show that damage area is divided into two parts, and thermal dose of internal focus field decreases as a result of the existence of blood vessel; while the size of blood vessel, blood flow velocity or blood perfusion rate increase, the ranges of effective thermal dose obviously decrease; blood vessel is closer to internal focus field, the influence is bigger.
