Abstract
The distribution of ohmic power in a CAT scan section of a human chest irradiated with 915 MHz peripheral sources is calculated using the moment method. In the simulation, the chest section (assumed to be uniformally developed along the cranio-caudal axis for a height equivalent to the field penetration) is subdivided in 235 subvolumes of known electric constants. The focusing of power on a selected region of the chest is obtained by properly exciting the sources. An optimization method allows selecting the amplitudes and phases in such a way that the power level in all subvolumes outside the focal region is kept below a given threshold.
