Patent application numberTitlePublished
20110297839SOLID-BODY X-RAY IMAGE DETECTOR WITH CIRCULAR DETECTOR SURFACE AREA - A solid-body X-ray image detector and method of manufacturing the same are disclosed. The detector has a circular surface area arrangement of CCD or CMOS detector pixels on a substrate, a scintillator arranged on the substrate, and a circular detector surface area, wherein the substrate comprises a single, substantially circular silicon wafer and the detector surface area takes up the surface area of the silicon wafer up to a narrow edge region.12-08-2011
20110168878METHOD AND APPARATUS FOR EMPIRICAL DETERMINATION OF A CORRECTION FUNCTION FOR CORRECTING BEAM HARDENING AND STRAY BEAM EFFECTS IN PROJECTION RADIOGRAPHY AND COMPUTED TOMOGRAPHY - Methods for empirical determination of a correction function for correcting beam hardening and stray beam effects of water-equivalent tissue in projection radiography or computed tomography using an imaging detector, and apparatuses for implementing the same are disclosed. The projection values obtained from the logarithmic values of the detector signals are corrected, the corrected projection values being represented by a correction function dependent on the tube voltage applied during the X-ray projection recording, the coefficients of which function are determined from a single calibration scan on an object-like calibration phantom made of water-like material.07-14-2011
20080285725METHOD AND APPARATUS FOR CALIBRATING AN X-RAY DIAGNOSTIC SYSTEM - The subject matter of the present application relates to methods for calibrating an X-ray diagnostic system and apparatus for use in the calibration methods. In one embodiment, the apparatus includes a position detection system having an acquisition unit. An X-ray phantom is disposed near the acquisition unit in a known position and/or orientation relative to a coordinate system of the position detection system. The X-ray phantom may be detachably mounted on the acquisition unit.11-20-2008
20080285724X-RAY DIAGNOSTIC IMAGING SYSTEM WITH A PLURALITY OF CODED MARKERS - Embodiments of an X-ray diagnostic imaging system comprise a plurality of coded 2D and/or 3D markers associated with surfaces of system components. The position and coding of at least some of the coded markers can be determined by a position detection system. In some embodiments, a coded marker is assigned a reference point having a known position on the surface of the system component. The positions of the system components in space can be calculated based at least in part on a reference point network determined from the position of the individual reference points measured with the position detection system. In some embodiments, the coded markers represent information with a data matrix code (DMC).11-20-2008
20080285721LOCALIZING UNIT FOR AN X-RAY DIAGNOSTIC SYSTEM WITH A STERILE DRAPE - The disclosure relates to a localizing unit for an X-ray diagnostic system covered with a sterile drape. In one embodiment, the localizing unit can be sterilized and has an adapter, which includes a means for puncturing the sterile drape and a means for temporarily securing the sterile drape on a housing of the X-ray diagnostic system. The adapter may be detachably held in predetermined holders on the housing of the X-ray diagnostic system and may be positioned on the housing in a reproducible manner. In some embodiments, the means for temporarily securing the sterile drape on the housing includes an elastically deformable, surrounding seal, which upon positioning the adapter, produces a force on the sterile drape in a direction perpendicular to the surface of the housing.11-20-2008
