A method for generating rules for rule-based reasoning includes the steps of starting from a set of generic reasoning rules generating a set of specific reasoning rules by substituting in at least one of the generic reasoning rules having more than one variable, at least one of the variables with (a) class(es) defined in an ontology.


An apparatus for reading out X-ray information stored in a storage phosphor layer includes a light source for generating stimulating light which can stimulate the storage phosphor layer to emit stimulated emission, an optical fiber, in particular a single mode fiber, which is optically coupled to the light source and generates a stimulating light beam from the stimulating light, and a deflection element for deflecting the stimulating light beam to move over the storage phosphor layer.


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


A radiographic flat panel detector includes a layer configuration in the order given: a) a radiation transparent substrate; and b) a scintillator layer applied by means of vapour deposition on the radiation transparent substrate; and c) an imaging array between the scintillator layer and a second substrate, characterised in that the radiation transparent substrate has on a side a layer including magnetizable particles and a method for producing the radiographic flat panel detector.


A storage phosphor plate assembly includes at least one storage phosphor plate having a storage phosphor layer for storing X-ray information and a substrate layer on which the storage phosphor layer is provided. The substrate layer contains a permanent magnetic material, and a support plate contains a magnetic material, the at least one storage phosphor plate being held on the support plate due to magnetic forces. The invention further relates to an X ray cassette and a system for reading out storage phosphor plate. An easy and safe handling of storage phosphor plates of various sizes and/or forms, in particular during the read-out process in the read-out system, is achieved.

A method of automatically configuring an X-ray imaging system for taking an X-ray image of an object includes, first, obtaining one or more depth images from one or more depth cameras covering at least an area covered by an X-ray bundle of an X-ray source. Then, a thickness of the object is determined from the depth image(s). Then, this thickness value is converted to a dose configuration of the X-ray imaging system by taking into account a transmission length of the X-ray bundle through the object and knowledge about tissue types being imaged.
