The Propeller technique is a useful
acquisition scheme and reconstruction method to reduce motion artifact. However, the higher specific absorption rate (SAR)
of RF pulse at high-field magnetic strength can limit the number of multiple
slices for a given TR, which in turn reduces the efficiency of acquisition,
especially for Propeller-FSE sequence. A possible solution is to reduce the
echo-train-length with under-sampling of data of each blade.
In this study, we propose to apply POCSMUSE instead of SENSE
reconstruction and Propeller reconstruction, to reconstruct the image from all
under-sampled blade data with reduced noise amplification. The data acquired
from brain and liver using Propeller-GRE will be used to test purposed POCSMUSE
algorithm.
