Abstract: A detector for a dark-field and/or phase-contrast interferometric imaging system comprises pixels, first detector arrays, second detector arrays, and a processor. For each pixel, each of the first and second detector arrays is configured to detect a cumulative charge associated with fingers of the respective detector array. For each pixel, the processor is configured to assign an X-ray interaction event to either the first detector array or the second detector array based on the detector array that has the highest cumulative charge.

Abstract: The invention relates to a system for reconstructing an image of an object. The system (100) comprises means (110) providing projection data acquired by an imaging unit, like a CT system, with an FOV, means (120) generating estimated image data indicative of a part of an object (20) located outside the FOV (210), means (130) estimating virtual projection data based on virtual settings of a virtual imaging unit comprising a virtual FOV, means (140) generating fused projection data by fusing the provided projection data with the virtual projection data, and means (150) reconstructing a final image. This allows basing the reconstruction on a complete set of projection information for the object and thus providing an image with a high image quality.

Abstract: A diaphragm imaging device includes at least one electronic processor programmed to perform a diaphragm imaging method including receiving ultrasound imaging data of a diaphragm of a patient, the ultrasound imaging data being acquired by an associated ultrasound imaging probe with the probe at a plurality of different observable probe angles (βobs); for each observable probe angle, determining a corresponding apparent thickness (dI) of the diaphragm of the patient from the received ultrasound data acquired at that observable probe angle; and estimating a thickness (dD) of the diaphragm of the patient based at least on the apparent thicknesses (dI).

Abstract: The present invention relates to an apparatus (10) for generating X-ray imaging data. It is described to position (210) a first grating between an X-ray source and a second grating. The second grating is positioned (220) between the first grating and a third grating. A third grating is positioned (230) between the second grating and an X-ray detector. An object is positioned (240) between the first grating and the third grating. At least one of the three gratings has a pitch attribute of having a constant grating pitch. At least one of the three gratings has a pitch attribute of having a varying grating pitch. Both gratings of an adjacent pair of gratings are bent such that a distance between the two adjacent gratings is constant as a function of fan angle. Both gratings of the adjacent pair of gratings that are bent have the same pitch attribute. An X-ray detector detects (250) at least some of the X-rays transmitted by the three gratings and the object.

Abstract: An interferometer grating support (118) of an imaging system (100) configured for grating-based x-ray imaging includes at least two elongate supports (302) separated from each other by a non-zero distance, wherein the at least two elongate supports have a first end (312) and a second end (316). The grating support further includes a first arc shaped grating (202) affixed to the first end and a second arc shaped grating (204) affixed to a second end (316). A non-transitory computer readable medium is configured with computer executable instructions which when executed by a processor of a computer cause the processor to: move a grating support, which supports G0 and G1 gratings of an interferometer and a bowtie filter, into a region between a low energy photon filter and a beam collimator, which are between a radiation source and an examination region, for a grating-based x-ray imaging scan.
