Abstract: The present invention is a directed to a non-pixelated scintillator array for a CT detector as well as an apparatus and method of manufacturing same. The scintillator array is comprised of a number of ceramic fibers or single crystal fibers that are aligned in parallel with respect to one another. As a result, the pack has very high dose efficiency. Furthermore, each fiber is designed to direct light out to a photodiode with very low scattering loss. The fiber size (cross-sectional diameter) may be controlled such that smaller fibers may be fabricated for higher resolution applications. Moreover, because the fiber size can be controlled to be consistent throughout the scintillator array and the fibers are aligned in parallel with one another, the scintillator array, as a whole, also is uniform. Therefore, precise alignment with the photodiode array or the collimator assembly is not necessary.

Abstract: A radiation detector (24) for an imaging system includes a two-dimensional array (50) of nondeliquescent ceramic scintillating fibers or sheets (52). The scintillating fibers (52) are manufactured from a GOS ceramic material. Each scintillating fiber (52) has a width (d2) between 0.1 mm and 1 mm, a length (h2) between 0.1 mm and 2 mm and a height (h8) between 1 mm and 2 mm. Such scintillating fiber (52) has a height (h8) to cross-sectional dimension (d2, h2) ratio of approximately 10 to 1. The scintillating fibers (52) are held together by layers (86, 96) of a low index coating material. A two-dimensional array (32) of photodiodes (34) is positioned adjacent and in optical communication with the scintillating fibers (52) to convert the visible light into electrical signals. A grid (28) is disposed by the scintillating array (50). The grid (28) has the apertures (30) which correspond to a cross-section of the photodiodes (34) and determine a spatial resolution of the imaging system.

Abstract: A two-dimensional ionising particle detector including a matrix of detecting fibers, each detecting fiber forming a pixel of the detector. Each detecting fiber is composed of a glass capillary filled with a liquid scintillator for which the chemical composition is chosen such that an average free path of primary scintillation photons is negligible compared with a diameter of the capillary. The detector is applicable, for example, to high resolution particle imagery.

Abstract: A radiation detection device, system, and method for use in homeland security is disclosed. The device is portable and includes a photomultiplier tube (PMT) connected to an end of a substantially rigid thin-walled aluminum tube. Inside the aluminum tube, a substantially straight scintillating fiber is disposed (so as to be shielded from ambient light), and an end of the scintillating fiber is optically coupled to the PMT. A voltage output signal from the PMT is signal-processed with a filter to remove high-frequency noise (which may arise from solar radiation spikes) and fed to a voltage-responsive alarm or signalling device. The portable device is employed, for example, by responders to nuclear incidents and is packaged as a small wearable hands-free and eyes-free unit with a continuous in-use self-testing feature.
