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 ...
A General Local Reconstruction Approach Based on a Truncated Hilbert Transform
Exact image reconstruction from limited projection data has been a central topic in the computed tomography (CT) field. In this paper, we present a general region-of-interest/volume-of-interest (ROI/VOI) reconstruction ...
