To achieve meaningful phase imaging on the Siemens 7T systems a uniform sensitivity Roemer coil combination was implemented to replace the standard sum of squares or adaptive combine algorithm. This code, including additional noise sampling sequences, is available on request to William Clarke, University of Oxford (william.clarke@ndcn.ox.ac.uk) and on receipt of suitable authorisation from Siemens Healthineers.
