Abstract

Optimization of an antenna for magnetic resonance imaging (MRI) requires an accurate analysis of antennas loaded by a human body. We have developed a computer code for obtaining the current distribution on the antenna loaded by a human model with an arbitrary geometry and material properties by incorporating the impedance method into the Richmond method. Numerical results for the input impedance are compared with measured impedances confirning the validity of the proposed method. Furthermore, sensitivity. distributions of antennas loaded by a human model are calculated.
