title: Numerical calculation of electromagnetic energy and temperature distribution in a microwave irradiated breast carcinoma: preliminary results.
abstract: In this study an attempt was made to calculate temperature distribution in a breast tumor irradiated by microwaves. An ellipsoidal model of absorbing dielectric surrounded by a nonabsorbing medium irradiated by a plane wave was considered. The energy was calculated inside and outside the ellipsoid by an analytical method. Three-dimensional and densitographic patterns were calculated for different frequencies, conductivities and shapes of the model. Assuming experimental (in vivo) thermal properties of breast tissue thermal patterns were calculated.
