This abstract presents an approach that relies on the
interleaved combination of ZTE read-outs with different resolutions combined
with a Compressed Sensing reconstruction, to acquire more information around
the k-space center, for high-quality ZTE without prolonged acquisition times.
Figure 1: Coronal slice of a dedicated rubber phantom acquired at 15
mT/m gradient strength (A, B) and 24 mT/m (C, D). Images A and C were
acquired with the modified approach including the low-strength gradients.
Figure 3: Coronal slice of a wrist
acquired at 15 mT/m gradient strength (A, B) and 24 mT/m (C, D). Images A
and C were acquired with the modified approach including the low-strength
gradients.
