Radial Undersampling-Based Interpolation Scheme for Multislice CSMRI Reconstruction Techniques

Figure 7

Comparison of (a) original image with (b–f) reconstructed images using different reconstruction strategies and sampling ratios. (b) iCS reconstructed image has sharper details but with loss of information. (c) FiCS 2D-VRDU has preserved the original information but has a blurring effect which becomes more prominent when the undersampling ratio is reduced. (d) CS reconstruction using the proposed radial undersampling also shows severe degradation when the sampling ratio reduces. (e) FiCS-radial and (f) EiCS-radial has improved results compared to CS-radial but the sharpness degrades for (e) FiCS with 3% samples while the proposed (f) EiCS has improved results with clear and sharp details as pointed by the red arrow.
