Fig. 9From: Joint sparse reconstruction of multi-contrast MRI images with graph based redundant wavelet transformReconstruction errors of knee images (× 5) with 32% sampled data (Cartesian). Rows 1–3 correspond to multi-contrast images shown in Fig. 6(a-c) respectively. Column 1–4 denote the results obtained from GBRWT, JSIDWT, JBCS and JGBRWT reconstruction respectivelyBack to article page
