In this work, we compare of the performance of two popular RF coils used in high field MRI head applications, namely, the coax element TEM coil and the stripline element TEM coil. The comparison is performed using the finite difference time domain method. We load the coils with an accurate human head model, and tune and operate the coils at the proper frequency for proton imaging at 7 Tesla. We then compare the performance of the two coils by analyzing the B1+ and B1- fields, as well as the MR signals generated by both coils.
