Microwave Heating of a Cancer Tumor

Application ID: 30

Electromagnetic heating is ideally suited for modeling in COMSOL Multiphysics. This model shows the area of hyperthermic oncology but the modeling issues and techniques are generally applicable to any problem involving electromagnetic heating.

The purpose of this model is to compute the radiation field and the Specific Absorption Rate (SAR) in liver tissue for a thin coaxial slot antenna used in microwave coagulation therapy. A simulation of the resulting temperature distribution in the liver is also included.

This model example illustrates applications of this type that would nominally be built using the following products:
