Designing RF Refocusing Pulses for Parallel Transmit Spin Echo Sequences

INTRODUCTION Parallel transmission of RF pulses [1, 2] has shown great potential in B1 inhomogeneity correction at high fields [3]. Most of the existing applications of parallel transmission, however, have been restricted to only gradient echo due to lack of systematic design of parallel transmit refocusing pulses. The difficulty of designing such pulses… CONTINUE READING
