High resolution MRI image reconstruction from a PROPELLER data set of samples

Fixing Acceleration and Image Resolution Issues of Nuclear Magnetic Resonance

“…This area of interest has been especially has been researched in the latest years. The algorithm shown in this research paper enriches Iterative Back Projection (IBP) [1] and its improved version [2] in a few directions. It utilises a deformable image registration.…”

“…Yet, weakened image quality could be surmounted by utilising the proposed k-space sampling pattern. The sampling scheme suggested in this paper combines PROPELLER (Periodically Rotated Overlapping ParallEL Lines with Enhanced Reconstruction) sampling scheme [2] with Compressed Sensing and Partial Fourier, see Figure 1. The Partial Fourier framework claims that the phase changes gradually within the scanned object.…”

“…The combining of parallel imaging procedures with the Compressed Sensing methodology turns out to be more efficient in obtaining decreased image noise than with both the technologies used separately. In this work, the author presents a new MRI-associated method, which blends SR [2,3], deformable motion estimation with robust sampling trajectory pattern. The experimental results are promising and reveal the method's true value.…”
