N2 - A new algorithm for construction of artificial blood vessel networks and a new approach to simulate heat exchange in tissue are presented. The algorithm produces discrete three-dimensional geometric representations of both arterial and venous networks. The key feature of the algorithm is that growth begins from the root points and it can work with any enclosed geometry. The main difference of proposed method is that blood perfusion occurs mainly in capillary. Two different methods of constructing blood velocity vector field in tissue accounting capillary blood flow are presented. It is needed for precise thermal analysis using the modified bio-heat equation to provide better prediction of thermal response of tissues exposed to RF energy.
