Abstract
Optimizing RF coil currents' magnitude/phase relationship, temporal modulation and spatial distribution is crucial to MR imaging performance. One key aspect for the optimization is the knowledge of B1 spatial distribution and RF power deposition associated with a coil current pattern or a source configuration, and the use of the knowledge in the optimization. Another key aspect for the optimization is a hardware infrastructure that facilitates the optimization, with, specifically, a coil structure that supports flexible current path control. The present invention relates to calibration methods and multi-channel parallel RF transmit/receive coil assemblies that improve the performance of MR imaging by addressing both aspects.
