Abstract

The purpose of this paper is to evaluate the Specific Absorption Rate (SAR) distribution for tumour treatment when the electromagnetic field is emitted from a microwave ablation antenna operating in the 2.45 GHz. Firstly, the SAR distribution is simulated by CST Studio Suite, and the SAR measurement is carried out when the microwave antenna needle is inserted into a swine´s liver. The microwave radiation power is transferred into thermal energy. Finally, the results in comparing simulated and measured tests of SAR distribution are demonstrated.
