Error vs. radial acceleration. (a) TrACR-SENSE corrected CG-SENSE reconstructions for full sampling and 4× acceleration. (b) RMS k-Space trajectory error versus radial acceleration factor for GA radial TrACR-SENSE reconstructions with 15 coils. (c) Error versus number of coils used for TrACR-SENSE, for full sampling and 4× acceleration. All errors are expressed as multiples of 1/FOV and are referenced to the fully-sampled 32-channel TrACR-SENSE trajectory estimate.
