The essence of RF system performance optimization can be described as one of maximizing |B1|/|E|. Further, the RF current carried by the coil structure is the means by which an MR scanner implements and optimizes RF fields. Constellation coil, a new approach to RF coils, targets a supportive structure for ideal RF current patterns and thereby the ultimate performance. The approachs support for highly parallel Tx/Rx can also play a central role in overall scan performance enhancement. This study explores constellation coil designs. Full wave simulations as well as parallel Tx and Rx MR experiments were used to evaluate prototypes.
