A query rule set is created by applying a query generation query rule to an inference rule set so as to generate a query rule set via a reasoning process executed by a reasoner whereby said reasoner answers said query generation query rule by taking the basic graph pattern of the conclusion of one or more inference rules in said inference rule set and generating a corresponding query rule for said basic graph pattern, wherein in said generated query rule both premise and conclusion are using said basic graph pattern.


A method for reshaping the characteristic exposure response and dosimetry of a direct radiography system into a specified exposure response profile by pixel-wise converting image data according to a response transfer model which is derived from an x-ray generators post exposure parameters data associated with image signals obtained at various exposure levels during system calibration and from a few extra dose measurements and their corresponding post exposure data also gathered during system calibration under reference exposure conditions.


A scintillator comprising CsBrxl(1-X) doped with Europium (CsBrxl(1-X):Eu) wherein xxl(1-X):Eu material at a temperature from 50 C to 280 C characterised in that the EPR spectrum of the so obtained scintillator measured at room temperature at a frequency of 34 GHz, shows a maximum in signal height at a magnetic field of 1200 mT, the signal height at 1090 mT and 1140 mT not exceeding 40%, wherein the normalised signal height percentage at 1200 mT is calculated to be 100%. The scintillator is useful in high energy radiation detection and radiography imaging apparatus.

A computerized tomographic image exposure and reconstruction method wherein an object is subjected to irradiation during a relative movement of a source of radiation, said object and a radiation detector and wherein a digital representation of the radiation image of said object is computed by applying a tomographic reconstruction algorithm to image data read out of the irradiated radiation detector. A number of projection images are generated, each of said projection images being generated by integrating X-ray beams continuously emitted during said relative movement through a predefined movement path, and the created projection images are modeled in a tomographic reconstruction algorithm.

According to an embodiments, the invention relates to a n X-ray system (800) for taking an X-ray image of an object. The system comprises an X-ray source (808), an X-ray detector (811), depth camera(s) (801 ) covering at least an area covered by an X-ray bundle and configured to obtain depth images (852) and a client device (851) comprising a display adapted to display an impression image (854) to a user. The system further comprises a controller (850) configured to derive the impression image comprising a representation of this area from the depth images; and to obtain from the client device a first geometric position correction of the X-ray imaging system with respect to this impression image; and to convert the first geometric position correction (855) to an actual geometric position configuration (853) of the X-ray imaging system by an known relation between the one or more depth cameras and the X-ray imaging system.


The present invention relates to a method for triggering image capture by a group of simultaneously X-ray exposed multiple wirelessly interlinked self -triggering direct radiography (DR) detector assemblies, comprising the steps of performing an initiation step to identify said group of participating DR detector assemblies prior to X-ray exposure, detecting said X-ray exposure by a first participating DR detector assembly, said first participating DR detector assembly performing a trigger step to signal all participating DR detector assemblies to start image capture.
