Yarra integrated Matlab implementation of the basic GRASP reconstruction technique. Developed by Li Feng, Ricardo Otazo, and Kai Tobias Block.
This module uses several open-source Matlab packages developed by other contributors, including the mapVBVD library by Philip Ehses, the NUFFT library developed by Jeff Fessler, and the inifile reader developed by Primoz Cermelj. Please give credit to these developers when using the module.
This method implements the "GRASP" reconstruction for free-breathing DCE-MRI acquisitions, which has been described in the following publication:
