The Clinical and Research potential of MRI especially for Whole Body imaging is limitless. Body MR exams are growing part of total clinical MRI exams today. It however faces considerable challenges such as significant rise in RF power deposition in tissue and daunting high field inhomogeneities/signal voids across the anatomy of interest most especially at 7T and higher. This study aims at utilizing the intrinsic sensitivity advantage of 7T by exploring a 32-ch transmit coil design in order to generate a circularly polarized field with homogeneous and extended coverage in abdominal/body regions (liver, kidney, and abdomen in general) at 7T.
