Smooths a DWI dataset

Parameters

  • dwi ((X x Y x Z x N) img_like object) – Image to be corrected, where N is the number of volumes in the DWI acquisition.

  • csfmask ((X x Y x Z x N) img_like object) – The noise map from dwidenoise

  • width (float, optional) – The full width half max in voxels to be smoothed. Default: 1.25

Returns

corrected – The rician-corrected version of dwi

Return type

(X x Y x Z x N) array_like or img_like object

Parameters

  • dwiname (str) – Filename of image to be corrected

  • noisemapname (str) – Filename of noisemap to use for correction
