摘要： The invention relates to an X-ray detector with detector elements (1) arranged in a layer. The detector elements (1) contain a scintillator element (2) for the conversion of X-rays (X) into photons (v), a photodiode (5) for detection of the photons (v), and a processing circuit (4) for the processing of electric signals generated by the photodiode (5). In order to protect the electronics (4) from X-rays a shielding (3) of variable effective thickness (d1, d2) is disposed in front of the electronics (4). This shielding (3) can in particular be L-shaped. By reduction of the effective thickness of the shielding (3) to a necessary minimum the volume of the scintillator unit (2) can be maximized.

摘要： The invention relates to the field of X-ray differential phase contrast imaging. For scanning large objects and for an improved contrast to noise ratio, an X-ray device (10) for imaging an object (18) is provided. The X-ray device (10) comprises an X-ray emitter arrangement (12) and an X-ray detector arrangement (14), wherein the X-ray emitter arrangement (14) is adapted to emit an X-ray beam (16) through the object (18) onto the X-ray detector arrangement (14). The X-ray beam (16) is at least partial spatial coherent and fan-shaped. The X-ray detector arrangement (14) comprises a phase grating (50) and an absorber grating (52). The X-ray detector arrangement (14) comprises an area detector (54) for detecting X-rays, wherein the X-ray device is adapted to generate image data from the detected X-rays and to extract phase information from the X-ray image data, the phase information relating to a phase shift of X-rays caused by the object (18). The object (18) has a region of interest (32) which is larger than a detection area of the X-ray detector (18) and the X-ray device (10) is adapted to generate image data of the region of interest (32) by moving the object (18) and the X-ray detector arrangement (14) relative to each other.

摘要： The invention relates to a method and an imaging system (100) for generating X-ray images. The system (100) comprises at least one X-ray source, preferably an array of X-ray sources (101a-101d), and an X-ray detector (103) with an array of sensitive pixels (103a-103e). A collimator (102) is arranged between the X-ray source and the detector such that two openings (P) of the collimator (102) allow the passage of X-rays towards two neighboring pixels (103a-103e) while the region between said pixels is substantially shielded. This shielding of the usually insensitive regions between pixels reduces unnecessary X-ray exposure. A sufficiently large X-ray intensity can be achieved by using a plurality of small X-ray sources (101a-101d).

摘要： X-ray devices for Phase Contrast Imaging (PCI) are often built up with the help of gratings. For large field-of-views (FOV), production cost and complexity of these gratings could increase significantly as they need to have a focused geometry. Instead of a pure PCI with a large FOV, this invention suggests to combine a traditional absorption X-ray-imaging system with large-FOV with an insertable low-cost PCI system with small-FOV, The invention supports the user to direct the PCI system with reduced FOV to a region that he regards as most interesting for performing a PCI scan thus eliminating X-ray dose exposure for scanning regions not interesting for a radiologist. The PCI scan may be generated on the basis of local tomography.

摘要： The c-arm x-ray system according to the present invention presents a system that provides at least one x-ray beam projection and an auxiliary projection without the need to rearranging or move elements of the c-arm to avoid inaccuracies through mechanical deflection of the supporting c-arm. This is achieved by comprising a main x-ray source, and at least one auxiliary x-ray source with a lower continuously radiated power than the main x-ray source and mechanically coupled to the main x-ray source, which is formed as a cold carbon nanotube based field emitter.

摘要： The invention relates to an X-ray imaging device, particularly a Spectral-CT scanner, that comprises an X-ray source for generating X-radiation with an energy spectrum which varies continuously during an observation period. In a preferred embodiment, the radiation is attenuated in an object according to an energy-dependent attenuation coefficient μ, the transmitted radiation is measured by sensor units of a detector, and the resulting measurement signal is sampled and A/D converted. This is preferably done by an oversampling A/D converter, for example a ΣΔ-ADC. The tube voltage that drives the X-ray source is sampled with high frequency. In an evaluation system, these sampled measurement values can be associated with corresponding effective energy spectra to determine the energy dependent attenuation coefficient μ.

摘要： A tomographic apparatus (10) includes at least two x-ray sources (16) that are concurrently driven with different switching patterns to generate uniquely encoded radiation. The tomographic apparatus (10) further includes at least two detectors (20) that each detect primary radiation emitted by its corresponding one of the at least two x-ray sources (16) and cross scatter radiation from at least one of the other at least two x-ray sources (16). Each of the at least two detectors (20) produces an aggregate signal representative of the detected primary and cross scatter radiation. The tomographic apparatus (10) further includes a decoupler (30) which, based on the different switching patterns, identifies at least one signal corresponding to at least one of the at least two x-ray sources (16) within the aggregate signal and associates the identified signal with its corresponding x-ray source (16).
