This package provides MATLAB demos for the below class of learning methods are provided in dynamic MRI and diffusion MRI applications.
a) Sparsity and low rank constrained reconstruction (k-t SLR) [1]
b) Blind compressed sensing (BCS) [2] [3]
c) Explicit motion compensated recovery: Deformation correction compressed sensing (DC-CS) [4]
d) Patch based regularization for implicit motion compensation (PRICE) [5]
e) Smoothness regularization on a manifold (STORM) [6]
f) Multi shot sensitivity encoded diffusion data recovery using structured low rank matrix completion (MUSSELS) [7]
Demos are based on example raw single coil and multi coil Cartesian and non-Cartesian k-space datasets from a variety of applications involving arbitrary spatio-temporal dynamics and contrast changes. These include free breathing ungated cardiac cine MRI, free breathing myocardial perfusion MRI, vocal tract MRI during speech, multi-parametric MRI, and multi-shot diffusion weighted EPI.
