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 device for signal compensation in medical X-ray images. The device (100) comprises a generation module (10) configured to generate an X-ray ghosting image based on an X-ray detector read-out subsequent to a last X-ray exposure of a plurality of X-ray exposures; a scaling module (20) configured to scale the X-ray ghosting image into a scaled X-ray ghosting image; and a subtraction module (30) configured to subtract the scaled X-ray ghosting image from any subsequent X-ray image recorded during a respective subsequent X-ray exposure of the plurality of X-ray exposures.

Abstract: A method and system for processing a radiography image derived from an X-ray radiation passing through an object. The method includes acts of estimating, based on the radiography image, a scatter signal present in said radiography image; calculating, based on the estimated scatter signal, a scatter removal signal indicative of a scattered radiation removable from the X-ray radiation passing through the object by a reference anti-scatter device; and correcting the radiography image based on the scatter removal signal.
