摘要： The invention relates to an X-ray detector (30) that comprises an array of sensitive elements (Pi-1,b, Pia, Pib, Pi+1,a, Pi+1,b) and at least two analyzer gratings (G2a, G2b) disposed with different phase and/or periodicity in front of two different sensitive elements. Preferably, the sensitive elements are organized in macro-pixels (IIi) of e.g. four adjacent sensitive elements, wherein analyzer gratings with mutually different phases are disposed in front said sensitive elements. The detector (30) can particularly be applied in an X-ray device (100) for generating phase contrast images because it allows to sample an intensity pattern (I) generated by such a device simultaneously at different positions.

摘要： The invention is directed at an apparatus (10), an imaging device and a method for detecting X-ray photons, in particular photons (32,34) in a computer tomograph. Photons (32,34) are converted into an electrical pulse and compared against a threshold using a discriminator (20). The electrical network (12) performing these functions comprises a switching element (28), that can modify the electrical path (22) along which the process signals travel. The trigger signal (V T ) for actuating the switching element (28) is derived from an electrical state of the electrical path (22). If a pulse associated to a photon (32,34) is detected, the switching element (28) is actuated in order to avoid that the processing of the charge pulse stemming from a first photon (32) is affected by a subsequent second photon (34).

摘要： Computed tomography (CT) systems are provided that utilize x-ray tube spectra in connection with the generation and/or interpretation of CT data. The disclosed systems and methods use x-ray tube spectra associated with CT systems to enhance contrast and/or image quality, e.g., by making use of energy selective detection techniques. The x-ray spectra may be determined in a variety of ways, e.g., incorporation of a spectral x-ray tube model into the CT system, using the output of Monte-Carlo simulations, and/or processing measured experimental spectral tube data for the CT system. The x-ray tube spectra is generally generated by and/or stored in a computer system associated with the CT system and may be used in support of an energy selective detective method and/or generation of spectral CT images.
