The region is repaired by an optically transparent material so as to be smoothed. | 01-17-2013 |
| 20130140464 | RADIATION DETECTION PANEL - A radiation detection panel includes a single light emitting section, a first detection section and a second detection section. The single light emitting section absorbs radiation that has been transmitted through an imaging subject and that emits light. The first detection section detects light emitted from the light emitting section as an image. The second detection section that is formed from an organic photoelectric conversion material and that detects light emitted from the light emitting section. The light emitting section, the first detection section and the second detection section are stacked in layers along a radiation incident direction. | 06-06-2013 |

| 20130126743 | RADIATION DETECTOR - A radiation detector includes a scintillator layer, a first photoelectric conversion layer, a second photoelectric conversion layer, and one board or two boards. The scintillator layer, the first photoelectric conversion layer, the second photoelectric conversion layer, and the one board or two boards are layered. The first photoelectric conversion layer is constituted with one of a first organic material and an inorganic material with a wider radiation absorption wavelength range than the first organic material. The first photoelectric conversion layer absorbs at least light of a first wavelength and converts the light to charges. The second photoelectric conversion layer is constituted with a second organic material that is different from the first organic material. The second photoelectric conversion layer absorbs more of light of a second wavelength than of light of the first wavelength and converts the light to charges. | 05-23-2013 |
| 20130126742 | X-RAY RADIATION DETECTOR WITH AUTOMATIC EXPOSURE CONTROL - An apparatus and method for radiation detection is herein described. The apparatus consists of two radiation-detection arrays: A primary radiation-detection array, based on scintillator-CMOS design, and a secondary radiation-detection array, mounted on the back of said primary array. A method of controlling the detection operation is described, where output of the secondary array is exploited for controlling the acquisition-start and acquisition-stop of the primary array. Further, the apparatus is equipped with fast memory for storage of correction tables, and with a processor for fast computation of the correction. A method of calibration is also describes with tables for: offset correction, gain correction, and for defect-pixel correction. These tables are evaluated by the fast processor and stored on the fast memory. A method of real-time evaluation of the signal corrections is described, which depends on the acquisition-start and acquisition-stop timings and which results a clean, artifact-free image. | 05-23-2013 |
