The similarity between images, in problems involving multiple acquisitions with different imaging parameters, is used as an additional reconstruction constraint beside sparity to further increase the quality of reconstruction/k-space under-sampling. This is of particular interest in reconstruction of T1/T2 maps. From a clinical perspective, this means a reduction in acquisition time.
