Tx-array elements that have B1 field distributions that are completely orthogonal may allow the complimentary effect of Rx-array data compression but on the transmit side for Tx-SENSE applications, minimizing the number of transmit channels required to achieve a certain Tx-SENSE reduction factor. Here we report on an eigenmode Tx-array solution that generates 8-channel orthogonal B1 fields used in conjunction with an 8-channel transmitter MRI system for Tx-SENSE MRI.
