Tensor-Based Formulation and Nuclear Norm Regularization for Multienergy Computed Tomography
Tensor-Based Formulation and Nuclear Norm Regularization for Multienergy Computed Tomography
The development of energy selective, photon counting X-ray detectors allows for a wide range of new possibilities in the area of computed tomographic image formation. Under the assumption of perfect energy resolution, here we propose a tensor-based iterative algorithm that simultaneously reconstructs the X-ray attenuation distribution for each energy. We …
