X-ray crystallography, like mass spectroscopy and nuclear spectroscopy, is an extremely useful material characterization technique that is unfortunately hard for amateurs to perform. The physical o… ...
This paper proposes a distance-driven projection method which is targeted to single-pinhole single-photon emission computed tomograghy (SPECT) imaging since it accounts for the finite size of the ...
This work presents an analytical method for calculating the system matrix for a DC-SPECT system. The solid angle calculation is adapted for a square-shaped pinhole collimator. The calculated ...
