SART-Type Image Reconstruction from Overlapped Projections
To maximize the time-integrated X-ray flux from multiple X-ray sources and shorten the data acquisition process, a promising way is to allow overlapped projections from multiple sources being simultaneously on without ...
Inverse Fourier Transform in the Gamma Coordinate System
This paper provides auxiliary results for our general scheme of computed tomography. In 3D parallel-beam geometry, we first demonstrate that the inverse Fourier transform in different coordinate systems ...
SART-Type Image Reconstruction from a Limited Number of Projections with the Sparsity Constraint
Based on the recent mathematical findings on solving the linear inverse problems with sparsity constraints by Daubechiesx et al., here we adapt a simultaneous algebraic reconstruction technique (SART) for image reconstruction ...
