 # NORDIC_Raw
 Matlab code for performing image reconstruction in MRI and performing the NORDIC denoising
+
+The two files NORDIC and NIFTI_NORDIC perform similar concepts, locally low-rank denoising.
+Both approaches, uses a g-factor map to flatten the noise, and a noise-scan for estimating the homoegenous noise.
+For NORDIC, the noise-scan and the g-factor are explicit constructions provided as the last elements in a 4D array.
+For NIFTI_NORDIC, these are estimated based on the data. The construction for estimating the g-factor noise and the thermal noise level
+uses the MPPCA method of Veraart et al. 2016
+NIFTI_NORDIC has additional paramters that can be adjusted, for learning or understanding the influence of the different algortimic choices.
+For NIFTI_NORDIC, there are two different options, depending on whether dMRI or fMRI is used. 
+This difference appears related to the hwo the phase is retained in the DICOM of the vendor software. A corresponding distinction is not neccesary for the NORDIC processing.
+
+This version of NIFTI_NORDIC has been made possible through the testing and evaulation of many people, including
