Abstract: Described herein is a tray sanitization assembly including a tray sanitization source positioned within a tray return system and configured to sanitize a baggage handling tray conveyed therethrough. Also described is a tray return system including a conveyor assembly including a conveyor for translating a baggage handling tray in a tray transfer direction, and the tray sanitization assembly.

Abstract: A detector assembly for a CT imaging system is provided. The detector assembly including a scintillator block including a plurality of pixels, each pixel configured to receive x-ray beams travelling in a transmission direction, a plurality of photodiodes, and a light guide coupled between the scintillator block and the plurality of photodiodes, the light guide including a plurality of light pipes, each light pipe configured to guide light emitted from a pixel of the plurality of pixels into an associated photodiode of the plurality of photodiodes, wherein each pixel has a first cross-sectional area that is substantially perpendicular to the transmission direction, wherein each photodiode has a second cross-sectional area that is substantially perpendicular to the transmission direction, and wherein the first cross-sectional area is different from the second cross-sectional area.

Abstract: A scintillator assembly for use in a CT imaging system is provided. The scintillator assembly includes a frame including a base, and a plurality of walls extending substantially perpendicular from the base, wherein the base and the plurality of walls define a plurality of pixel compartments, and granular scintillating material contained in at least some of the plurality of pixel compartments, wherein the granular scintillating material is configured to convert x-ray beams into light.

Abstract: A radiation detector is provided. The radiation detector includes an outer casing, at least one first detector disposed within said outer casing, the at least one first detector configured to primarily detect gamma ray radiation, at least one second detector disposed within the outer casing, the at least one second detector configured to primarily detect neutron radiation, and a computing device disposed within the outer casing and communicatively coupled to the at least one first detector and the at least one second detector. The computing device is configured to receive first data from the at least one first detector, receive second data from the at least one second detector, determine a number of neutrons and gamma rays detected based on the first and second data, and determine a detected energy spectrum based on the first and second data.
