FIELD: physics.
SUBSTANCE: proposed process comprises the steps that follow. Sub-sampled spectrum in k-space is produced and sub-sampled positions in k-space is initialized by initial approximation. Initially reconstructed spectrum is subjected to multiband decomposition to some separate spectra. Reconstruction is performed with application of CRD images corresponding to appropriate decomposed bands. Reconstructed images are combined to get the resultant target image. Note here that said initialization is executed by regularization of l1-norm. Reconstruction is calculated with application of CRD by alternating scattered approximation and recovery of measured frequencies.
EFFECT: accelerated reconstruction.
