Radiofrequency Ablation - Complex Numerical Models 

Description:

These models were constructed to study the effects of blood flow on the size and shape of the RF lesion. More complex vessel and needle geometries were considered. The following figures show the geometry of the computational domain (vessel, tissue and needle) as well as details of the finite element grid.
