Abstract :
A new technique for microwave (2450 MHz) heating of C3H mammary tumors is described. 1 cm tumors were encapsulated in 5 cm spheroids of a material dielectrically similar to biological tissues. When similarly heated, encapsulated tumor exhibited far more front-to-back temperature uniformity than unencapsulated tumors. Encapsulation also improved coupling of microwave heating fields. Tissue-simulating spheres were microwave-heated to the same temperatures in an anechoic range. Central temperature distributions were similar to those in the encapsulated tumors and agreed with theoretical predictions.
