Abstract :
The electromagnetic field near clinically applied coaxial microwave applicators for interstitial hyperthermia is calculated using a finite integration algorithm program. Simulations of E-field and SAR distributions of different conventional applicators in a muscle phantom are presented and compared with measurements. The applied calculation method allows also design optimization and improvement of more sophisticated applicator types, e.g. those using a triaxial technique.<>
