In this work, we implement a single optimized phased-array excitation scheme on a 3 Tesla whole-body RF coil to maximize the B1+ (transmit) field uniformity throughout a large abdominal 3-D portion of a human body load. We compare the uniformity of the B1+ field (in the entire 3D abdominal volume encapsulated within the coil structure) resulting from the one unique optimized phased-array excitation to the uniformity resulting from standard quadrature excitation and conclude that the proposed optimized excitation scheme holds much potential in producing highly homogeneous images of large abdominal volumes at 3 Tesla.
