Abstract:
We have used the three-dimensional impedance 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. We compare the energy deposited in several tumor sites when energy is applied using a variety of applicator sizes, locations, and boluses of various conductivities. We show detailed maps of the power deposition in these cases for selected regions of the body and suggest useful configurations of applicators for heating tumors in several locations in the body.
