Regional hypothermia through endorectal cooling balloon (ECB) is shown capable of minimizing the long term urinary incontinence and sexual dysfunction. However, there is no tool to optimize ECB setting to reach the desired protective cooling effect. A bioheat simulation equation based on each individual patients own 3D anatomy is developed to model the cooling process by using the finite element method. Using this model, we evaluated the impact of geometrical distance from ECB, the balloon temperature, and the presence of blood. In addition, the effect of arterial ligation to decrease the blood perfusion to NBV was also evaluated.
