20090045347 | Detector module, radiation detector and radiation recording device - A detector module is disclosed including a plurality of directly converting detector submodules, each with a back contact, and a scattered radiation collimator spanning the detector submodules. For contacting the back contacts, a contacting unit is provided in at least one embodiment and designed so that a contact connection is established between the contacting unit and the counter-electrodes by way of assembly-related proximity of the scattered radiation collimator and the counter-electrodes. | 02-19-2009 |
20100014633 | Scattered radiation collimator, radiation detector and radiation detection device - A scattered radiation collimator is disclosed for radiological radiation. In at least one embodiment, the scattered radiation collimator includes a multiplicity of absorber elements connected one behind the other in a collimation direction and at least two plate-like holding elements which are arranged substantially parallel with respect to one another and have absorber element holders for holding the absorber elements. In order to avoid erroneous positioning when transverse forces are acting, it is proposed in at least one embodiment, to connect the holding elements to each other by cross beams running along the end face of the absorber elements. | 01-21-2010 |
20110108745 | SCATTERED-RADIATION COLLIMATOR AND METHOD FOR PRODUCING A SCATTERED RADIATION COLLIMATOR - A scattered-radiation collimator is disclosed for radiological radiation with a multiplicity of absorber elements that are arranged one behind the other in a collimation direction and held in a support frame. In at least one embodiment, the support frame includes a holding device for holding the absorber elements on opposite sides across the collimation direction, and at least one strip-like holding element spans the absorber elements in a collimation direction on the radiation entry side and/or the radiation exit side of the scattered-radiation collimator and additionally fixes the absorber elements on the longitudinal edges thereof in a mechanical fashion. In at least one embodiment, the holding elements prevent deformations of long absorber elements caused by centrifugal forces to a large extent. This affords the possibility of implementing scattered-radiation collimators with a large Z-coverage that meet the demand on the absorber elements in respect of dimensional stability and positional accuracy. Moreover, at least one embodiment of the invention relates to a method for producing such a scattered-radiation collimator. | 05-12-2011 |
20120132833 | COLLIMATOR FOR A RADIATION DETECTOR AND METHOD FOR MANUFACTURING SUCH A COLLIMATOR AS WELL AS METHOD FOR MANUFACTURING A RADIATION DETECTOR COMPRISING COLLIMATORS - A collimator is disclosed for a radiation detector including at least three spacing elements arranged on a radiation exit face of the collimator. In at least one embodiment, they are embodied so as to mount the collimator in a stable manner with respect to a radiation converter of the radiation detector. The at least three spacing elements enable a very precise and stable alignment of the collimator in respect of the radiation converter despite manufacturing-related curves or unevennesses in the radiation exit face and/or the mounting surface on the part of the radiation converter. At least one embodiment of the invention also relates to a manufacturing method for such a collimator, as well as a method for manufacturing a radiation detector. | 05-31-2012 |
20120132834 | 2D Collimator For A Radiation Detector And Method For Manufacturing Such A 2D Collimator - A 2D collimator is disclosed for a radiation detector. In at least one embodiment, the 2D collimator includes 2D collimator modules arranged in series, wherein adjacent 2D collimator modules are glued together to establish a fixed mechanical connection to facing module sides, and wherein, on their free-remaining side, the outer 2D collimator modules have a retaining element for mounting the 2D collimator opposite a detector mechanism. A method for manufacturing such a 2D collimator is also disclosed. | 05-31-2012 |
20130134313 | DETECTOR ARRANGEMENT OF AN IMAGING SYSTEM DETECTOR DETECTING IONIZING RADIATION WITH AIR COOLING AND METHOD FOR COOLING THE DETECTOR ARRANGEMENT - A detector arrangement of an imaging system detector detecting ionizing radiation includes a detector carrier, a plurality of detector modules attached to the detector carrier, and a collimator disposed in the radiation direction in front of the detector modules which are disposed on the incident radiation measurement side. In at least one embodiment, at least one air gap is included for conveying cooling air is disposed between the collimator and the measurement sensors of the detector modules. A method is also disclosed for cooling a detector arrangement of a detector rotating around a system axis with a plurality of measurement sensors disposed next to one another and a collimator arranged in the radiation direction in front of the measurement sensors, wherein cooling air is conveyed in or against the system axis direction between the collimator and the measurement sensors which directly cools the surface of the measurement sensors. | 05-30-2013 |
20130306877 | X-RAY DETECTOR - An x-ray detector, especially for a computed tomograph, includes a number of detector modules arranged next to one another in a stacking direction with a front side, which during operation is oriented towards an x-ray source, and with a rear side lying opposite the front side. For screening against x-rays which pass during operation through an installation between two adjacent detector modules, an absorption element is positioned on the rear side of the two adjacent detector modules. | 11-21-2013 |
