Tensor decomposition and non-local means based spectral CT image denoising
BACKGROUND: As one type of the state-of-the-art detectors, photon counting detectors are used in spectral computed tomography (CT) to classify the received photons into several energy channels and generate multichannel projections simultaneously. However, FBP reconstructed images contain severe nois...
