Fig. 1From: Joint sparse reconstruction of multi-contrast MRI images with graph based redundant wavelet transformFlowchart of the proposed method. The x ref denotes the reference image used to train the graph wavelet transform, y1, y2, ⋯, y T denote the under-sampled k-space data of multi-contrast images, \( {\widehat{\mathbf{x}}}_1,{\widehat{\mathbf{x}}}_2,\cdots, {\widehat{\mathbf{x}}}_T \) denote the reconstructed imagesBack to article page
