Blade by Blade Compressed Sensing for PROPELLER

Eric Aboussouan¹, Jim Pipe¹

This work proposes to use compressed sensing to fill missing lines of individual PROPELLER blades which are then gridded together. By making use of the inherent data redundancy of PROPELLER, such a scheme is thought to greatly reduce the risk of losing image features, which can be a concern with iterative reconstruction methods. This method could be used in applications where parallel imaging is not suitable (e.g. for PROPELLER spine imaging).
