20120112076REMOTE DETECTION OF RADIATION - Various embodiments of the present invention provide a method of detecting inaccessible radiation sources by measuring corresponding ions and excited molecules created by radiation, using LIDAR technology. The LIDAR system of the present invention employs a pulsed laser transmitter, a telescope receiver, and associated control and acquisition systems. Light propagates out from the laser transmitted and is directed into the volume surrounding the radioactive source, or the “ion cloud.” The ion cloud absorbs the transmitted light, which induces the non-fluorescing ions to fluoresce. Light from the ion cloud is then backscattered and the telescope receiver subsequently collects the photons from the backscattered light. The intensity of the fluorescence (determined by the photon count) is measured, which provides an indication of the number density of the ionized atoms. Algorithms can then be used to relate the measured ionization rates to the source activity.05-10-2012

A gap is formed between at least a part of a side of the tips of the columnar crystals and the protection material. The radiological image detection apparatus includes a radiological image conversion panel and a sensor panel that is provided close to the fluorescence emitting surface of the phosphor to detect the fluorescence emitted from the phosphor.11-01-2012
20110233411Method of managing radiation detectors, radiographic image capturing apparatus, and radiographic image capturing system - A method of managing radiation detectors allows the radiation detectors to be assembled into a radiographic image capturing apparatus such that defective pixels of the radiation detectors are not disposed at the same pixel position (coordinates). The method comprises the steps of recognizing the positions of defective pixels of a plurality of manufactured radiation detectors, referring to the recognized positions of the defective pixels, and assembling at least two radiation detectors into the radiographic image capturing apparatus in a superposed relationship, such that the defective pixels of the radiation detectors are not superposed one on the other.09-29-2011
20110309250Methods for Manufacturing Three-Dimensional Devices and Devices Created Thereby - In certain exemplary embodiments of the present invention, three-dimensional micro-mechanical devices and/or micro-structures can be made using a production casting process. As part of this process, an intermediate mold can be made from or derived from a precision stack lamination and used to fabricate the devices and/or structures. Further, the micro-devices and/or micro-structures can be fabricated on planar or nonplanar surfaces through use of a series of production casting processes and intermediate molds. The use of precision stack lamination can allow the fabrication of high aspect ratio structures. Moreover, via certain molding and/or casting materials, molds having cavities with protruding undercuts also can be fabricated. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. This abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.12-22-2011

20120025085ION DETECTOR - An ion detector for detecting positive ions and negative ions, includes a housing provided with an ion entrance to make the positive ions and the negative ions enter, a conversion dynode which is disposed in the housing and to which a negative potential is applied, a scintillator which is disposed in the housing and has an electron incident surface which is opposed to the conversion dynode and into which secondary electrons emitted from the conversion dynode are made incident, a conductive layer which is formed on the electron incident surface and to which a positive potential is applied, and a photodetector which detects light emitted by the scintillator in response to incidence of the secondary electrons.02-02-2012
20080308734RADIATION IMAGE CONVERSION PANEL, SCINTILLATOR PANEL, AND RADIATION IMAGE SENSOR - The radiation image conversion panel in accordance with the present invention has an aluminum substrate; an alumite layer formed on a surface of the aluminum substrate; a chromium layer covering the alumite layer; a metal film, provided on the chromium layer, having a radiation transparency and a light reflectivity; an oxide layer covering the metal film and having a radiation transparency and a light transparency; a protective film covering the oxide layer and having a radiation transparency and a light transparency; and a converting part provided on the protective film and adapted to convert a radiation image.12-18-2008
20100320389RADIATION DETECTOR AND TOMOGRAPHIC EQUIPMENT PROVIDED WITH THE SAME - A radiation detector according to this invention has a first reflector frame and a second reflector frame. Each of scintillation counter crystals is inserted in a direction through the first reflector frame and the second reflector frame, whereby two or more scintillation counter crystals are arranged in a first direction and a second direction to form a scintillation counter crystal layer. A position of the first reflector frame provided in the scintillation counter crystal layer differs from a position of the second reflector frame provided in the scintillation counter crystal layer. With such construction, the radiation detector may be provided of significantly suppressed manufacturing costs without reducing spatial resolution and detecting sensitivity.12-23-2010
