At ultra-high field (UHF), multi-channel
radio-frequency (RF) arrays have found increasing utility in mitigating
wave-like behaviour during transmission (1), while
continuing to provide increases in sensitivity to MRI signal with densely filled
conformal receive arrays (2). In an
effort to more efficiently excite spin populations, and increase sensitivity to
the transverse magnetization during relaxation, work into mixing array elements
of dissimilar radiation pattern has been demonstrated to better encapsulate UHF
ideal current patterns (3). Application of our method - coupling matrix
synthesis - is used to robustly decouple a sample of these array-types.
