TL;DR: In this paper, the authors proposed a continuously rotating positron ECT system, in which the detectors are arranged on a circular ring with "non-uniform" spacing so as to provide much finer sampling interval in the projections than the conventional circular ring system.

TL;DR: In this article, the design of a whole-body, multislice Positron CT with three detector rings, 160 BGO crystal/ring, and a continuously rotating scan is described.

TL;DR: In this article, an apparatus for detecting the location of incident radiation comprises at least one pair of assembly comprised of a scintillation crystal consisting of a plurality of crystal segments, and a pair of photo-multiplier tubes optically coupled to the crystal so as to be able to detect scintillations produced in any one of these crystal segments.

TL;DR: In this article, the authors proposed to increase the propagation efficiency of light between the scintillator and the photo detector by forming the silicon nitride film on the inorganic scintillation surface with plasma glow discharge.

TL;DR: In this article, an apparatus for effecting positron emission computed tomography comprises rows of a plurality of arrays of detectors arranged rotatably around a center of rotation in such way that at least one of the detectors in each array is desposed at an irregular position relative to the rest of detectors in the array, and that, for each revolution of the row through an angle of 360°/n (wherein: n represents an odd number of 3 or larger), each array of detectors will assume exactly the position occupied by its adjacent array till the revolution takes place.
