    Abstract: A Positron Emission Tomography (PET) device, detector for a PET device and method of performing PET. The detector includes a scintillator and a photodetector. The scintillator includes a crystal defining a receiving axis and having a receiving face for receiving a gamma ray. A dopant concentration of the crystal varies along the receiving axis with a distance from the receiving face. The photodetector is configured to generate an impulse response in response to an interaction between the gamma ray and the crystal. A decay profile of the impulse response is related to a local dopant concentration of the crystal at the location of the interaction and the distance of the interaction from the receiving face.

  • Patent number: 10591614
    Abstract: A large-area directional radiation detection system useful in detecting shielded radiological weapons may include a large number of prism-shaped detectors stacked in a two-dimensional array of particle detectors in which alternate detectors are displaced frontward and rearward in, for example, a checkerboard-type arrangement of detectors. If a source of radiation is in front of the array, the frontward detectors act as collimators for the rearward detectors, thereby producing a narrow detection peak among the rearward detectors. The lateral position of the detection peak indicates the lateral position of the source, and the width of the detection peak indicates the distance of the source from the detector array, thereby providing a three-dimensional determination of the source location.

  • Patent number: 10565734
    Abstract: An image capture system includes a plurality of image sensors arranged in a pattern such that gaps exist between adjacent image sensors of the plurality of image sensors. Each of the image sensors may be configured to capture sensor image data. The image capture system may also have a main lens configured to direct incoming light along an optical path, a microlens array positioned within the optical path, and a plurality of tapered fiber optic bundles. Each tapered fiber optic bundle may have a leading end positioned within the optical path, and a trailing end positioned proximate one of the image sensors. The leading end may have a larger cross-sectional area than the trailing end. Sensor data from the image sensors may be combined to generate a single light-field image that is substantially unaffected by the gaps.

  • Patent number: 10408947
    Abstract: In the present invention, an integrated scintillator and collimator array for a detector utilized in a CT imaging system is provided. The integrated scintillator and collimator assembly is are fabricated from a manufacturing process or technique in which a scintillator array including a number of scintillation pixels is optically measured to determine the precise position of each pixel on the array. A transition material is applied to the array in a 3D printing method using the position data from the optical measurement and in subsequently bonded thereto in a sintering process to form a transition material layer. A collimator material is then 3D printed onto the transition material layer using the optical measurement data to form collimator plates on the array in alignment with the pixels thereby forming a unitary scintillator/collimator assembly for use in a detector for a CT imaging system.
