Visual quality comparison on GE MR images reconstructed by the four approaches from radially undersampled -space data (25.16%). (a) From left to right: ground truth image and images reconstructed by the DDTF, DLMRI, GradDLRec, and proposed TRIMS; each one has an enlarged region for a closer comparison. (b) From left to right: color axis and difference images of the DDTF, DLMRI, GradDLRec, and TRIMS.
