pygrappa.seggrappa

Python implementation of the Segmented GRAPPA algorithm.

pygrappa.seggrappa.seggrappa(kspace, calibs, *args, **kwargs)

Segmented GRAPPA.

See pygrappa.grappa() for full list of arguments.

Parameters:calibs (list of array_like) – List of calibration regions.

Notes

A generalized implementation of the method described in [1]. Multiple ACS regions can be supplied to function. GRAPPA is run for each ACS region and then averaged to produce the final reconstruction.
