A Bayesian Hyperparameter Inference for Radon-Transformed Image Reconstruction

Figure 8

Comparison of the reconstructed images using real CT data with Poissonian 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 the number of sampling in the acceptance-rejection method. We also show the magnification of around bronchus indicated by black rectangle in the true image.
