A Bayesian Hyperparameter Inference for Radon-Transformed Image Reconstruction

Figure 7

Comparison of the reconstructed images using real CT data with Gaussian noise between Bayes method and conventional FBP method. The top row shows the results of our method, and the bottom one shows the conventional FBP results. Each column corresponds to the strength of the observation noise that can be denoted as standard deviation (SD) of adding noise. We also show the magnification of a part around the bronchus, whose location is indicated by black rectangle in the true image.
