System and method of computed tomography imaging using a focused scintillator and method of manufacturing same

摘要

The present invention provides a detector for a CT imaging system. The detector includes a focused scintillator for receiving and converting high frequency electromagnetic energy to light energy. The detector further includes a photodiode positioned adjacent to the scintillator and configured to receive light energy discharged through a light exiting surface of the scintillator. The detector also includes electrical leads to transmit signals from the photodiode to a data processing unit for image construction. The CT system also provides for a gantry having an output for projecting high frequency electromagnetic energy toward the scintillator. A method of use and method of fabricating the tapered scintillators of the tapered scintillator array are also disclosed.
