Image Denoising and Ring Artifacts Removal for Spectral CT via Deep Neural Network
The spectral computed tomography (CT) based on photon counting detectors can collect the incident photons with different energy ranges. However, due to the low photon counts in narrow energy bin and the unhomogeneous response problem of detector cells, there are severe noise and ring artifacts in re...
