The Fourier reconstruction of a head section
L. A. Shepp,B. F. Logan +1 more
TL;DR: The authors compare the Fourier algorithm and a search algorithm using a simulated phantom to speed the search algorithm by using fewer interactions leaves decreased resolution in the region just inside the skull which could mask a subdural hematoma.
Journal ArticleDOI
Reconstructing Interior Head Tissue from X-Ray Transmissions
L. A. Shepp,B. F. Logan +1 more
TL;DR: In this article, a modified version of a previously studied algorithm was used to reconstruct the attenuation coefficients of a simulated head section from x-ray transmission measurements, which was then used to perform absolute measurements of attenuation coefficient at points interior to the skull.
Journal ArticleDOI
A New Design for High Speed Computerized Tomography
D. Maydan,L. A. Shepp,Z. H. Cho +2 more
TL;DR: In this article, a rotating cathode filament with a fixed large stationary circular anode is used to provide a planar X-ray image of the human heart, where the detectors near the focal point are moved synchronously out of the slice plane.
