The essence of constellation coil transmit and/or receive performance optimization can be described as one of maximizing |B1|/|E|, quantities that track flip angle-to-SAR ratio (spin excitation) and signal-to-noise ratio (signal detection). It uses an approximately continuous RF structure as well as multiple distributed ports to support generally sophisticated RF current patterns responsible for the ultimate performance with multi-channel transmit and receive1. And the transmit and receive ports location are very critical to the ultimate performance.
