A CT Reconstruction Algorithm Based on Non-Aliasing Contourlet Transform and Compressive Sensing
Figure 6
The relationship of RMSE and UQI with respect to projection number . (a) and (b) are the RMSE and UQI of reconstructed images from noise-free data with ART, ART-TV, and SpBr-NACT method, respectively. (c) and (d) are the RMSE and UQI of reconstructed images from noisy data with ART, ART-TV, and SpBr-NACT method, respectively.
