A CT Reconstruction Algorithm Based on Non-Aliasing Contourlet Transform and Compressive Sensing
Figure 3
The reconstructed images using three different reconstruction algorithms from the noise-free and noisy data. Top row is for noise-free data and bottom row is for noisy data. (a) and (d) are reconstructed by ART, (b) and (e) are reconstructed by ART-TV, and (c) and (f) are reconstructed by SpBr-NACT method.
