Abstract: An image processing system and related method. The system comprises an input interface (IN) for receiving dark-field image data obtained from imaging of an object (OB) with an X-ray imaging apparatus (XI). A corrector module (CM) of the system (IPS) is configured to perform a correction operation to correct said dark-field image data for Compton scatter to obtain Compton-Scatter corrected image data. The so Compton scatter corrected image data is output by an output interface (OUT) of the system.

Abstract: The present invention relates to an apparatus (10) for feature suppression in dark field or phase contrast X-ray imaging. The apparatus comprises an input unit (20), a processing unit (30) and an output unit (40). The input unit is configured to provide the processing unit with an X-ray attenuation image of a region of interest of an object. The input unit is also configured to provide the processing unit with a dark field or phase contrast X-ray image of the region of interest of the object. The processing unit is further configured to identify a first feature in the X-ray attenuation image; to identify a second anatomical feature in the X-ray attenuation image; and to identify the second anatomical feature in the dark field or phase contrast X-ray image. The first feature is an obscuring anatomical feature depicted in the X-ray attenuation image with higher contrast than in the dark field or phase contrast X-ray image. The processing unit is also further configured to register the dark field or phase contrast X-ray image to the X-ray attenuation image based on the identified second anatomical feature. The processing unit is configured to determine a location of the first feature in the X-ray attenuation image; and to locate the first feature in the dark field or phase contrast X-ray image comprising utilization of information relating to the first feature identified in the X-ray attenuation image by transferring the determined location to the dark field or phase contrast X-ray image. The processing unit is still further configured to suppress the first feature in the dark field or phase contrast X-ray image to generate a feature suppressed dark field or phase contrast X-ray image. And the output unit is configured to output data representative of the feature suppressed dark field or phase contrast X-ray image.

Abstract: An X-ray imaging detector (102) is proposed, wherein the X-ray imaging detector comprises an X-ray converter (103) for converting X-ray radiation into electrical charges. The X-ray imaging detector further comprises a detector plate (104) for collecting the electrical charges generated by the X-ray converter and for generating an image. In addition, the X-ray imaging detector comprises a structured plate (105) for modulating the intensity of backscattered X-ray radiation, wherein the structured plate is arranged at a side of the detector plate opposite the side of the X-ray converter. Moreover, the X-ray imaging detector comprises a data processing system, which is configured for mitigating image distortions caused by backscattered X-ray radiation. Thereto, the data processing system uses information about the structured plate.

Abstract: The present invention relates to processing X-ray images of an object. In order to improve the accuracy for interactive geometrical measurements, a device (10) for processing of an X-ray image of an object (30) is provided. The device comprises an input unit (12) and a processing unit (14). The input unit is configured to provide a shape related information (16) from an object (30) to be irradiated. The input unit is also configured to provide a generic object model (20), and to provide an actual X-ray image (18) of the object. The processing unit is configured to adapt the generic object model based on the shape related information in order to generate an individual object model (22). The processing unit is also configured to determine, based on the individual object model, an individual image processing modificator (24) for processing at least one part of the X-ray image, and to apply the individual image processing modificator for further processing of the X-ray image.

Abstract: The present invention relates to a method, and a corresponding device, for testing a radius of curvature and/or for detecting inhomogeneities of a curved X-ray grating for a grating-based X-ray imaging device. The method comprises generating a beam of light diverging from a source point, propagating along a main optical axis and having a line-shaped beam profile. The method comprises reflecting the beam off a concave reflective surface of the grating. A principal axis of the concave reflective surface coincides with the main optical axis and the source point is at a predetermined distance from a point where the main optical axis intersects the concave reflective surface. The method comprises determining whether a projection of the reflected beam in a plane at or near the source point is present outside a central region around the source point, in which an absence of this projection outside the central region indicates that a radius of curvature of the concave reflective surface corresponds to the predetermined distance and/or that the reflective surface is substantially homogeneously curved along a curve formed by the beam impinging on the concave reflective surface.
