Abstract

A two dimensional model based on a computerized tomography (CT) scan from the pelvic region has been used to predict the specific absorption rate (SAR) patterns, to test the feasibility of such an approach. The results indicate that significant improvement can be achieved in the deposited power pattern using the phase focus technique at lower frequencies of operation (60 to 70 MHz). However, at higher frequencies (> 70 MHz) it is necessary to use some amplitude control. A selected example from the number of predicted SAR patterns is presented in this report to demonstrate the feasibility of the concept.
