Compressive Computed Tomography Reconstruction through Denoising Approximate Message Passing
X-ray computed tomography (CT) reconstruction from a sparse number of views is a useful way to reduce either the radiation dose or the acquisition time, for example in fixed-gantry CT systems; however, this results in an ill-posed inverse problem whose solution is typically computationally demanding. Approximate message passing (AMP) techniques …
