Abstract: The present invention provides methods and devices for making an anti-scatter grid for a radiographic imaging device identifiable. A method for providing an anti-scatter grid (100) for a radiographic imaging device comprises forming, by an additive manufacturing process, a grid pattern (110) in accordance with a product specification of the anti-scatter grid (100) to be provided; and forming, by an additive manufacturing process, a number of structural modifications (121) in or at the grid pattern in a manner making the number of structural modifications (121) image-based recognizable when the anti-scatter grid (100) is viewed according to its intended use in a viewing direction from a radiation source of the radiographic imaging device, and in a unique identification pattern (120) creating a unique identifier to make the anti-scatter grid to be provided identifiable among one or more others.

Abstract: An image processing system (IPS) and related method. The system (IPS) comprises an input interface (IN) for receiving an image (IM) of an object (OB) acquired by an imaging apparatus (IA). A kernel provider (KP) of the system (IPS) is configured to provide respective scatter kernels for at least two scatter types. A scatter correction module (SCM) of the system (IPS) is configured to perform a correction in the image based on the provided at least two kernels.

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: Calibration methods and related calibration controllers (CC) for calibrating imaging apparatuses (102) such as a 3D computed tomography imager or a 2D x-ray imager. The imaging apparatuses (102) are equipped with a dynamic beam shaper (RF). The dynamic beam shaper (RF) allows adapting the energy profile of a radiation beam (PR) used in the imaging apparatuses (102) to a shape of an object (PAT) to be imaged. A plurality of gain images are acquired in dependence on a shape of the object and the view along which the gain images are acquired or a target gain image is synthesized from a plurality of basis gain images (BGI).

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.

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: An interventional X-ray system is proposed, the system including a multi X-ray source unit positioned below a patient table. This ‘multiblock’ may comprise several x-ray sources with focal spot positions distributed along the x-y (table) plane. The x-ray sources are operable in a switching scheme in which certain x-ray sources may be activated in parallel and also sequential switching between such groups is intended. The switching may be carried out so that several images with different projection angles can be acquired in parallel. In other words, an optimal multi-beam X-ray exposure is suggested, wherein fast switching in one dimension and simultaneous exposure in the 2nd dimension is applied.

Abstract: The disclosure relates to an X-ray imaging system for acquiring two-dimensional or three-dimensional images of a subject. A relative position of an X-ray emitting region, as seen in a coordinate system which is stationary relative to an anti-scatter arrangement and/or an X-ray sensitive surface is controlled so that a first and a second image are acquired at different relative positions of the X-ray emitting region relative to the anti-scatter arrangement and/or the X-ray sensitive surface (10). A data processing system of the imaging system generates an output image, based on each of the images. In the output image, artefacts generated by the anti-scatter arrangement, are reduced, suppressed or eliminated compared to the first and the second image.

Abstract: Method for estimating radiation dose received by a tissue of interest during an imaging scan comprising: i, obtaining image data of a body region including the tissue of interest, ii. sub-dividing the image data into axial slices, comprising tissue axial slices and non-tissue axial slices, iii. determining a net amount of radiation dose emitted or received by each axial slice by combining scan parameters of each axial slice with pre-calculated amounts of radiation dose, iiii summing the net amounts of radiation dose of all the tissue axial slices to obtain a tissue dose.
