A sliding interleaved cylinder (SLINCY) acquisition
employs a 3D concentric cylinders trajectory as the
readout instead of a 3DFT sequence. Due to the helical
sampling geometry of the trajectory and the
sliding-nature of the acquisition scheme, a dedicated
parallel imaging strategy is required for SLINCY to
achieve a clinically feasible scan time. In this work,
we developed a new parallel imaging strategy for SLINCY,
which decomposes the 3D helical structure of SLINCY into
a series of 2D Cartesian planes. We demonstrated that
the proposed parallel imaging strategy is feasible for
SLINCY, which reduced the scan time down to almost 50%.
