reconstruction of multi-channel coil data is based on sensitivity maps for
receive coils retrieved from either a pre-scan or by autocalibration of
sensitivities from the scan itself. The implications of moving objects and
moving coils on reconstruction performance with static coil sensitivity maps
are shown on basis of simulated free-breathing contrast enhanced myocardial
perfusion imaging.
