Generalized low‐rank nonrigid motion‐corrected reconstruction for MR fingerprinting

Purpose Develop a novel low‐rank motion‐corrected (LRMC) reconstruction for nonrigid motion‐corrected MR fingerprinting (MRF). Methods Generalized motion‐corrected (MC) reconstructions have been developed for steady‐state imaging. Here we extend this framework to enable nonrigid MC for transient imaging applications with varying contrast, such as MRF. This is achieved by integrating low‐rank dictionary‐based compression into the generalized MC...
