Several major obstacles have dampened wide implementation of multi-transmission methods including requirements to have the knowledge of how the RF fields produced by current MRI coils/arrays behave in every imaged subject using B1 field measurement/mapping prior to performing the multi-transmission experiment. This work aims overcoming this subject-dependence issue while maintaining a high-SNR intact through the development of subject-insensitive multi-transmit arrays with receive-only inserts.
