Microwave Hyperthermia, Microwave Ablation (MWA), Coaxial Slot Antenna, Finite Element Method (FEM), Liver Cancer, Specific Absorption Rate (SAR).Abstract
Invasive microwave hyperthermia is a technique applied for treatment of cancer in which body tissue is exposed to high temperatures. The effectiveness of hyperthermia depends upon the temperature achieved during the therapy and the distribution of microwave thermal field; which further depends upon the type of microwave radiative antenna. Microwave ablation (MWA) or high temperature hyperthermia is a minimally invasive technique used to treat liver cancer, the effectiveness of which depends on highly localized spherical shaped leison with minimum back radiations near the tumor cells.
