Multi-slab 3D TSE imaging has better scan efficiency
than its single-slab counterpart but suffers ringing and
venetian blind artifacts. Meanwhile, spiral acquisition
has high SNR efficiency and has been incorporated into
3D TSE imaging, but mostly using a spiral-out only
trajectory. In this work we propose a 3D TSE technique,
using a spiral-in/out trajectory to provide higher SNR
efficiency, using sliding-slab to minimize the venetian
blind artifacts, and using non-uniform slice phase
encoding to reduce the ringing artifacts. The
preliminary results demonstrate that the image quality
is comparable to 2D Cartesian results.
