A Bayesian Hyperparameter Inference for Radon-Transformed Image Reconstruction

Figure 5

Comparison of the reconstructed tomography images derived using the Bayesian method and conventional FBP under the Poissonian noise. The top row shows the results of our method, and the bottom one shows the results of the conventional FBP method. Each column corresponds to the strength of the observation noise which can be denoted as the number of sampling in the acceptance rejection method. We show the magnification of a part of the reconstructed images around the edge of the phantom, whose location is indicated by a white rectangle in the true image.
