An RF coil plays a central role in the induction of a B1 field for creating an excitation profile, and meanwhile, a concomitant E field that causes undesirable RF loss and SAR. A coil structure that supports flexible current distribution control is essential for management of both the excitation profile and RF power, and is hence a key factor in parallel Tx performances. We developed a constellation coil which prioritizes field optimization-based Tx/Rx improvement with a continuum structure, and accommodates scalability supporting highly parallel Tx/Rx. Preliminary 7T MRI results obtained with prototype parallel Tx and Rx constellation coils are presented.
