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 may 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.

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 dosimeter for an x-ray brachytherapy system permits in situ monitoring and control of radiation treatment via a miniaturized energy transducer within a human body. The dosimeter comprises a scintillating optical fiber having a distal end which is placed at the treatment site and a proximal end which is coupled to a dosimeter measurement unit. Utilizing energy supplied by an energy source, the miniaturized transducer generates x-ray photons. The scintillating optical fiber absorbs x-ray photons, converts the x-ray photons into light photons, and conveys the light photons to a dosimeter measurement unit. The light photons are converted into an electrical current which is representative of the intensity of the x-ray photons. The dosimeter measurement unit utilizes the electrical current to calculate and display the instantaneous and accumulated radiation dose, and radiation dose parameters are utilized to adjust energy levels, which are sent to the miniature energy transducer. Use of the miniaturized energy transducer in combination with the dosimeter eliminates most of the problems related to the methods based on the use of radioactive sources and offers a method for efficient, accurate, and controllable radiation treatment.

Abstract: A contraband detection system (18) using a single, cone shaped neutron beam determines substances concealed in a sample object by developing total neutron cross section spectra for a plurality of elements, including carbon, nitrogen, oxygen, hydrogen and other potential contraband-indicating elements. A processor (26) performs a contraband determination classification based on the neutron total cross section spectra for the plurality of elements, including hydrogen and elements which do not have peaks in the energy range of interest. The contraband detection system (18) includes a neutron source (20) for producing a pulsed, cone shaped beam of fast white neutrons; a spatial neutron detection array (40); a conveyor system (28) for situating a sample object (29) between the source (20) and the detection array (40); a spectra analysis system (24) for determining the neutron total cross section spectra of elements located in the sample object; and the processor (26). The neutron source (20) produces a pulsed beam (36) of fast white neutrons having sufficient energy range whereby removal of neutrons from the beam caused by the presence of a plurality of contraband-indicating elements can be determined. Various techniques of making contraband classification determinations are also disclosed.
