Abstract :
The authors have used the three-dimensional method to calculate the power deposition in the human pelvic region due to a radio-frequency current at 13.56 MHz applied through round or oval capacitive-plate applicators. They compare the energy deposited in several tumor sites when energy is applied using a variety of applicator sizes and locations and boluses of various conductivities. Detailed maps of the power deposition in the these cases for selected regions of the body are shown as well as useful applicator configurations for heating tumors at several locations in the body.
