With a traditional cylindrical strip array coil, one cannot accelerate a 3D pulse sequence along z since all the coils present the same sensitivity profile in this direction. To overcome this limitation, we propose to twist the striplines along the substrate, such that the aliased data for a given coil element do not overlap in z in undersampled acquisitions. This permits use of SENSE or GRAPPA in two phase-encoding directions, achieving higher acceleration factors without increasing the number of receiving channels.
