Publication number: 20110096904Abstract: A radiation damage resistant linear X-ray detector system based on a unique image transferring principle to alter the optical path and thus reduces or eliminates the X-ray radiation damage on the electrical components of the detector system. The system includes a layer of scintillating material, a fiber optic face plate (FOFP), and an array of image sensors. One face of the FOFP is bonded to the surface of the image sensors. The layer of scintillating material, such as Gd2O2S:Tb (GOS or GADOX), CsI(TI), or CdWO4, is placed on other face of the FOFP and used to convert the impinging X-ray energies into visible light which can be detected efficiently by the image sensor array. The FOFP is used to transfer the visible light from the scintillating layer onto the image sensor array after the X-ray flux has been converted.Type: ApplicationFiled: October 26, 2009Publication date: April 28, 2011Inventors: Hsin-Fu Tseng, Linbo Yang

Publication number: 20110075811Abstract: In a cassette-type X-ray detection device, an X-ray detector and a self diagnostic circuit are contained in a cassette casing. When the cassette-type X-ray detection device gets a shock, the self diagnostic circuit is actuated. The self diagnostic circuit reads out from the X-ray detector an offset image being a dark current image, and analyzes the offset image. The self diagnostic circuit finds out an abnormal portion from the offset image, and diagnoses whether the X-ray detector is available, unavailable, or partly available based on the size and position of the abnormal portion. Shock detection and a diagnostic result are displayed on a touch panel provided in the cassette casing, and sent to a console device via a communication unit.Type: ApplicationFiled: September 9, 2010Publication date: March 31, 2011Applicant: FUJIFILM CorporationInventor: Jun Enomoto
