Abstract
(A1) Zur Erfassung eines Bildes, das von einer Bildquelle erzeugt wird, ist eine Spiegelanordnung zwischen der Bildquelle und einem Detektor angeordnet. Die Spiegelanordnung umfasst zwei voneinander beabstandete Umlenkspiegel, die zueinander parallel sind oder einen spitzen Winkel kleiner als 90° zueinander bilden. Insbesondere dann, wenn die Bildquelle eine Szintillatorschicht ist, wird damit eine Abschirmung von Roentgenstrahlen vor dem Detektor bei gleichzeitiger kompakter Abmessung der Vorrichtung erreicht.
US 20090196400 A1 UPAB: 20090824 NOVELTY - The apparatus has a detector (120) i.e. photosensitive sensor, for receiving radiation deflected by a mirror arrangement (110). One mirror reflects light radiation (102) generated by an image source (100) e.g. scintillator, and another mirror reflects the radiation (119) reflected by the former mirror. A third mirror reflects radiation reflected by a fourth mirror. An X-ray absorber material e.g. lead, is arranged between the latter mirror and the fourth mirror or the latter and fourth mirrors are configured on different sides of a support material e.g. glass, absorbing X-rays (99). DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method of detecting an image (2) a method of manufacturing an apparatus for detecting an image. USE - Apparatus i.e. X-ray camera, for detecting an image for medical radioscopy application. ADVANTAGE - The mirror arrangement is sandwiched between the detector and the image source, thus providing a compact, simple and cost efficient apparatus. The apparatus enables subdividing the scintillator screen in a simple manner, where the scintillator area having any size can be imaged by a large number of optical cameras without changing the structural depth. The individual images are composed using a computer so as to prevent image losses. The modular architecture of the apparatus enables imaging any size and the shape of the scintillator by adding mirrors or detector cameras that detect different regions, thus enabling providing an apparatus adapted to the size and the shape of a device under test.
