The effects of high dielectric material (HDM) in human MRI have been studied intensively in recent years. Most of the effort has been made to understand the effect of HDM from the aspect of the transmit EM field. In this study, we took consider also the receive EM field in simulation of a 4-channel phase array. The transmit EM field analysis was done to validate the simulation, followed by the receive EM field analysis. The knowledge of the effect of HDM on the receive EM field will provide us a complete picture of the overall behavior of HDM in human MRI, providing better insight to HDM design and better performance of MRI.
