Abstract :
Optimization is performed of the specific absorption rate (SAR) distribution inside a human head phantom for hyperthermia treatment of brain tumor. Two implementations of phased array are presented, using four and eight antenna, respectively. SEMCAD-X simulation along with genetic algorithm (GA) optimization under Mat lab environment are conducted. Operation is performed at relatively low frequency values of 550-900 MHz to achieve good energy penetration. Results of SAR distribution illustrates the possibility of delivering microwave energy into relatively deep tumor positions with reduced heating side effects on the surrounding healthy tissue.
