If a many-element RF coil array could be mounted behind the scanner covers while preserving much of the SNR performance of close-fitting arrays, the benefits for patient comfort and simplicity of workflow would be dramatic. In numerical simulations and experimental evaluations of progressively larger encircling prototypes, we explored the feasibility of remote body array designs. Smaller-scale models performed well as compared with close-fitting counterparts. However, with a 50cm-diameter 124-element prototype, we encountered unexpected practical challenges, most notably relating to preamplifier noise coupling, which becomes significant in lightly-loaded many-element arrays. Effective remote array designs will have to contend with these challenges.
