Figure 3. In-vivo MR images of human feet in sagittal plane.

Each slice (i.e., slice #1, #3, #4, #6, #7, and #9) was reconstructed using the three methods: conventional full k-space reconstruction (which served as the reference in the 1^st column), conventional Compressed Sensing at undersampling rate of 1/100 (in the 2^nd column), conventional Compressed Sensing at undersampling rate of 1/11 (in the 3^rd column), and the proposed interpolated CS methods at the undersampling rate 1/100 (in the 4^th column). In this comparison study, image quality improvement of the iCS reconstruction method is observed compared with the CS method, much image details being recovered.
