  • Publication number: 20100148076
    Abstract: When a first image capturing apparatus installed in an image capturing room is selected and a power supply switch of a radiation converter used in the first image capturing apparatus is turned on, a controller generates an image capturing apparatus identification signal for specifying the image capturing apparatus, and sends the identification signal together with ID information of the selected image capturing apparatus stored in an ID memory to a console in the image capturing room via a transceiver by wireless communications. The console reads image capturing conditions for the selected image capturing apparatus from an image capturing condition storage unit, and supplies the conditions to a radiation generator for recording a radiographic image in the radiation converter. The radiation generator controls a radiation source according to the supplied conditions to emit radiation for recording a desired radiographic image on a radiation conversion panel of the radiation converter.

    Abstract: A Method for determining the material composition of a material sample which emits radiation comprises the following method steps: recording a spectrum of the energy deposited in a detector material by the radiation; determining a first energy deposited in a first energy range, a second energy deposited in a second energy range, and a third energy deposited in a third energy range; assigning a first colour parameter to the first deposited energy, a second colour parameter to the second deposited energy, and a third colour parameter to the third deposited energy; and comparing the assigned colour parameters with predetermined values for the colour parameters, the predetermined values typically corresponding to colour parameters of a predetermined material composition.

  • Patent number: 7576332
    Abstract: The invention provides an imaging system using an inherently non-imaging detection probe, linked to a, position and optional contact-sensing device, for use in scanning a surface having a surface radiation flux. The system has processing means to take signals from the detection probe and sensing devices, and to create an image of the geometry of the surface, and of the surface radiation flux. The system also provides means to determine the depth of a radiation source below the surface. The system also has means to present this image to a user.

  • Publication number: 20090194702
    Abstract: A preferred embodiment comprises a method and system for (a) detecting objects or targets which may or may not be nonreflective to electromagnetic radiation, and/or (b) generating an image of a subject or area, comprising generating an entangled photon pair beam; splitting the entangled photon pair beam into first and second parts; the first parts being directed in a first direction towards a first location, and the second parts being received into a measuring device; measuring the physical characteristics of the conjugate second parts to determine whether or not the first parts have encountered the presence or absence of an object at the first location in combination with the time that the first part takes to enter the first location. The method and system incorporate a photon beam in a reference path that never directly interacts with the object yet is determinative of presence or absence of an object at the first location.

  • Patent number: 7550738
    Abstract: A radioisotope identification and localization device having at least one radiation detector with three dimensional event localization that utilizes a spatial correlation of projection vectors arising from Compton scattering of gamma ray emissions. Source identification and location is supplied by a reconstruction that searches for solutions with radioactive material of unknown type. Detection, identification and localization does not require full energy deposition. Identification and location of known or unknown radioactive material somewhere in a large active area of interrogation is achieved.
