Radial Undersampling-Based Interpolation Scheme for Multislice CSMRI Reconstruction Techniques

Table 1

Comparison of the proposed radial undersampling schemes with 1D- and 2D-VRDU schemes, along with CS. The assessment has been done on 3 consecutive slices and averaged (slices 165-167 of the knee dataset).
