CG-SPIRiT and POCS-SPIRiT from 3-fold and 5-fold arbitrary Cartesian sampling using 8 channels. (a) 5-fold acceleration poisson-disc density sampling pattern and the reconstruction from the full data (b) Normalized RMSE (nRMSE) as a function of iterations. The advantage of SPIRiT shows at higher acceleration where efficient use of the acquired data becomes crucial. (c) Examples of the various reconstruction. Note the reduction in noise and artifacts in the SPIRiT reconstructions from 5-fold accelerated data.
