Joint multi-channel total generalized variation minimization and tensor decomposition for spectral CT reconstruction
2022
7th International Conference on Image Formation in X-Ray Computed Tomography
Photon-counting detector based spectral computed tomography (CT) has great potential in material decomposition, tissue characterization, lesion detection, and other applications. For a fixed total photon number or radiation dose, the increase of channel number will lead to the decrease of the photon number in each channel, resulting in degraded image quality of the reconstructed image. This is difficult to meet the practical applications for material decomposition, tissue characterization,
