摘要： A system and method of computer tomography imaging using a cerium-doped lutetium orthosilicate scintillator are provided. The system includes a high frequency electromagnetic energy projection source to project high frequency energy toward an object, such as a patient. A scintillator array having a plurality of cerium-doped lutetium orthosilicate scintillators therein receives the high frequency energy attenuated by the object and emits light energy based on the attenuated energy received. A photodiode array including a plurality of photodiodes is optically-coupled to the scintillator array and configured to detect the light energy and discharge output to a data processing system to produce a visual display. Each scintillator of the scintillator array is formed into a transparent glass ceramic having a high crystalline phase by combing glass-forming compounds in a glass forming system. A method of combining glass-forming compounds to form the cerium-doped lutetium orthosilicate into a transparent glass ceramic is also provided.

摘要： 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.

摘要： A multi-layer reflector for a CT detector is disclosed. The reflector includes an x-ray absorption component that is sandwiched between a pair of highly reflective components. Such a reflector is formed between adjacent scintillators of a CT detector so as to reduce cross-talk between adjacent scintillators as well as maintain a relatively high light output for signal detection. Moreover, the multi-layer reflectors may be disposed one-dimensionally or two-dimensionally across a scintillator array. A method of manufacturing such a reflector and incorporating same into a CT detector is also disclosed.
