The heart tissue is rich in blood, which flow is a thermal diffusion process; it can lead to lesion shape differences. The temperature distribution is very hard to obtain through the antenna specific absorption rate, thus affect curative effect. Based on the Pennes bioheat transfer equation, high flow rate of blood effect on microwave ablation in atrial fibrillation was analyzed. Lesion depths and...
Based on the Pennes bioheat transfer equation, location and flow rate of a large blood vessel effect on microwave thermal ablation was analyzed, in which the convection heat transfer of the cooling water was involved. Numerical results showed when the distance between the antenna and a blood vessel exceeded 20mm; the ablation area was elliptical-like. The blood vessel effect on the ablation can be...
Currently, the cardiovascular diseases threaten almost two in one thousand new borns all around the world. The treatment of these diseases mainly depends on the surgeons' experiences. Surgeons have to choose one of the assumed options for a patient without comparing which is more feasible. In this paper, a cardiovascular surgical planning system was proposed to help the surgeons predict the optimal...
