Proper reference for motion estimation is critical for
accurate and robust motion correction in PROPELLER MRI.
In this work, single blade reference (SBR), combined
blade reference (CBR), grouped blade reference (GBR) and
Pipe et als latest revised method in which no blade
reference is required (NBR) are implemented and
compared. Simulation results show that all methods above
is accurate enough to generate a good image. For some
special cases of in vivo imaging, SBR, CBR and GBR may
fail to converge, while NBR still maintains relatively
good performance, which indicates NBR is more robust.
