Abstract

The complexity of magnetic resonance imaging (MRI) at high magnetic field strength was studied using electromagnetic field calculations. The flip angle and coil sensitivity were demonstrated to be related to circularly-polarized components of the radio frequency (RF) field with opposite polarization. The results showed that very complicated signal intensity patterns at 300 MHz in a head-sized phantom can be explained with Maxwell equations and current MR theory of reciprocity.
