摘要： The invention relates to a detection apparatus for detecting radiation. The detection apparatus comprises a GOS material (20) for generating scintillation light depending on the detected radiation (25), an optical filter (24) for reducing the intensity of a part of the scintillation light having a wavelength being larger than 650 nm, and a detection unit (21) for detecting the filtered scintillation light. Because of the filtering procedure relatively slow components, i.e. components corresponding to a relatively large decay time, of the scintillation light weakly constribute to the detection process or are not detected at all by the detection unit, thereby increasing the temporal resolution of the detection apparatus. The resulting fast detection apparatus can be suitable for kVp-switching computed tomography systems.

摘要： The present invention relates to X-ray imaging technology. In phase-contrast imaging, different types of image information, e.g. absorption image information and differential phase-contrast image information, may be obtained by a single image acquisition process. Individual types of image information comprise different image properties. The present invention relates to a frequency dependent combination of different types of image information to obtain a combined image having improved properties over the individual image information and their respective image information type. Accordingly, an apparatus (56) as well as a method (100) for image processing in X-ray imaging of an object is provided comprising receiving (102) first image information of the object of a first image information type, receiving (104) second image information of the object of a second image information type,wherein the second image information type is different from the first image information type. Subsequently the first image information and the second image information is combined(106)to obtain combined image information of the object, wherein the combination of the first image information and the second image information is a frequency-dependent combination, depending on the spatial frequency of the first image information and the second image information.

摘要： The invention relates to a detection values processing apparatus. Energy- dependent detection values are provided, which are indicative of polychromatic radiation (4) after having traversed an examination zone (5). The radiation is filtered by a filter (15) which comprises K-edge filter material. A component decomposition technique is applied to the detection values for determining K-edge attenuation values being first component attenuation values, which are indicative of an attenuation caused by the K-edge filter material, and additional component attenuation values, which are indicative of an attenuation caused by additional components of the examination zone, wherein an image of the examination zone is reconstructed from the additional component attenuation values. An image can therefore be reconstructed, which is not adversely affected by the filter, because the K-edge attenuation values are not used for reconstructing the image. This can improve the quality of the reconstructed image.

摘要： An imaging system includes a radiation source (106, T1, T2, T3) that rotates about an examination region and emits radiation that traverses the examination region. The radiation source (106, T1, T2, T3) emits radiation having an energy spectrum that is selectively alternately switched between at least two different energy spectra during an imaging procedure.

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.

摘要： To mitigate the influence of charge sharing occurring in semiconductor detectors, an improved semiconductor detector (200) is provided, which comprises: a plurality of anodes (210) arranged to form at least one opening (230), each opening being formed by two anodes in the plurality of anodes; at least one cathode (220); a detector cell (240) located between the plurality of anodes and the at least one cathode; wherein the detector cell comprises at least one groove (250), each of the at least one groove having a first opening (252) aligned with one of the at least one opening being formed by two anodes in the plurality of anodes, each of the at least one groove extending towards the at least one cathode. By forming grooves in the detector cell, the charge cloud generated by a single photon can be received by a corresponding anode instead of several neighboring anodes, which thereby improves the spectral resolution and count rate of a semiconductor detector.
