  • Publication number: 20080001095
    Abstract: An adaptive imaging system includes a detector receiving energy transmitted through a target and generating electrical charge pulses at a pulse rate indicative of an intensity of received energy. The system also includes a switch for selectively coupling the charge pulses from one or more pixel elements of the detector to a charge pulse counter for counting the charge pulses and a charge pulse integrator for integrating the charge pulses. In addition, the system includes a prediction module for predicting a charge pulse rate expected to be produced by the detector and for operating the switch to selectively couple the charge pulses to the counter and the integrator responsive to a predicted charge pulse rate.

  • Patent number: 7212604
    Abstract: A computed tomography detector module is presented. The detector module includes a substrate having a topside and a bottom side. Additionally, the detector module includes a plurality of detector layers disposed on the top side of the substrate in a direction that is substantially orthogonal to the substrate, where each of the plurality of detector layers comprises a direct conversion material configured to absorb radiation, and where each of the plurality of detector layers comprises a first side and a second side. Further, the detector module includes a plurality of pixelated anode contacts is disposed on the first side of each of the plurality of detector layers. Also, the detector module includes a common cathode contact is disposed on the second side of each of the plurality of detector layers.

  • Patent number: 7098460
    Abstract: A conversion device for use in an imaging system is provided. The conversion device includes a first perforated plate portion forming a plurality of collimator channels separated by a plurality of thin collimator walls. A second perforated plate portion forming a plurality of scintillator channels separated by a plurality of thin scintillator walls is attached to the first perforated plate portion. A reflective coating is applied to the inside scintillator surface of the plurality of thin scintillator walls. A scintillator material is filled into the plurality of scintillator channels.

  • Patent number: 7084403
    Abstract: Scintillator materials based on certain types of halide-lanthanide matrix materials are described. In one embodiment, the matrix material contains a mixture of lanthanide halides, i.e., a solid solution of at least two of the halides, such as lanthanum chloride and lanthanum bromide. In another embodiment, the matrix material is based on lanthanum iodide alone, which must be substantially free of lanthanum oxyiodide. The scintillator materials, which can be in monocrystalline or polycrystalline form, also include an activator for the matrix material, e.g., cerium. Radiation detectors that use the scintillators are also described, as are related methods for detecting high-energy radiation.

  • Publication number: 20040227091
    Abstract: A method for detecting radiation using a monolithic detector is provided. The method includes providing a monolithic scintillator to interact with incident radiation and to generate a photon at a site of interaction, optically coupling a plurality of photosensors to the monolithic scintillator to detect the photon generated at the site of interaction, and configuring each photosensor to transmit a signal indicative of an amount of light detected by each photosensor and a solid angle covered by the photosensor relative to the site of interaction.
