A Bayesian Hyperparameter Inference for Radon-Transformed Image Reconstruction

Figure 2

Comparison of the reconstructed tomography images derived using the Bayesian method and conventional FBP. The top row shows the Bayesian FBP methods, and the bottom one shows the conventional one. Each column corresponds to the strength of the observation Gaussian noise standard deviations. We show the magnification of a part of the reconstructed images around the edge of the phantom, whose location is indicated by white rectangle in the true image.
