摘要： The invention relates to an imaging apparatus (31) for imaging an object. A reconstruction unit (12) determines component projection data values, which correspond to, for example, a base material of the object, and reconstructs an image of the object based on the determined component projection data values. A component projection data value, which corresponds to a ray, is determined as a combination of weighted base functions, which depend on energy projection data values of the same ray and the orientation of the same ray. This allows considering a possible dependency of the corresponding decomposition on the orientation of the ray, thereby allowing the imaging apparatus to improve the quality of decomposing the provided energy projection data values into the component projection data values and thus of a finally reconstructed image of the object, which is reconstructed based on the component projection data values.

摘要： The invention relates to a detection apparatus comprising a filter (20) for filtering a conical radiation beam (4) such that at least a first region (22) and a second region (23) of the radiation beam are generated having different energy spectra, wherein the first region of the radiation beam illuminates a first detector area (25) on a detection surface (21) of a detector, thereby generating a first set of detection values, and the second region of the radiation beam illuminates a second detector area (26) on the detection surface, thereby generating a second set of detection values. For example, by using the filter the detection apparatus can be used as dual-energy computed tomography apparatus, wherein, for instance, a standard computed tomography apparatus can be transformed to a dual-energy computed tomography apparatus by adding the filter to the standard computed tomography apparatus, preferentially without modifying the radiation source and the detector.

摘要： A computed tomography apparatus (10) includes spaced radiation sources (82, 84), such as anodes, which each propagate a cone -beam of radiation (40, 50) into an examination region (14). A detector (22) detects radiation which has passed through the examination region. An attenuation system (55) interposed between the radiation sources and the examination region for cone-angle dependent filtering of the cone beams. The attenuation system allows rays which contribute little to a reconstructed image to be attenuated more than rays which contribute more.

摘要： To scan an object with differently shaped cone beams (112, 122), the present invention provides a CT scanner with a moveable X-ray tube (the meaning of "move the x-ray tube among a plurality of predefined positions" also covers the situation that the anode disk is moved among a plurality of corresponding positions, while the shell of the x-ray tube does not move). The X-ray tube is not only moveable along the axial direction, but also along the radial direction of the CT scanner gantry. The scanner comprises an X-ray tube, which X-ray tube further comprises: an anode disk (100), comprising a plurality of focal tracks (110, 120) each focal track being cone-shaped with an anode angle (114, 124) different from the anode angle(s) of the other focal track(s); and a first cathode (210), configured to emanate an electron beam targeting at least one of the plurality of focal tracks. When different focal tracks are bombarded by electron beams, different X-ray beams (112, 122) with differently shaped cone beams are generated.
