A Bayesian Hyperparameter Inference for Radon-Transformed Image Reconstruction

<table>Qualities of reconstruction images measured by PSNR for real CT image reconstruction under the Poissonian noise. The horizontal axis shows the sampling level, and the vertical axis shows the PSNR. The solid line shows the result performance of Bayesian method, and the dashed line shows the results of the conventional FBP method.</table>
