Abstract: GC A phase contrast X-ray imaging system with field of view (FOV) visualization and a holder arranged to hold a grating and a light field projector to enable the FOV illumination, for an operator to visualize the region on a subject that will be irradiated with X-rays. By taking advantage of the holder of the necessary object in the X-ray beam path (i.e. the grating) to hold a light field projector to illuminate the FOV, the solution is naturally more compact to implement and the mechanical complexity is kept to a minimum. The light field projector provides a sharp, well-defined area with a distinct outline of the FOV.

Abstract: A mechanism for generating an artefact estimation image that represents the effect of cone-beam artefacts in a computed tomography (CT) image. This is achieved by identifying the position of gradients (being sudden changes of intensity) in an axis of the CT image parallel to a rotation axis of the CT system that generated the CT image, where each gradient represents a source of a cone-beam artefact. A look-up table is used to individually identify the effect of a cone-beam artefact on areas surrounding each identified position of the gradient, to generate an artefact estimation image.

Abstract: A method for use in a material decomposition procedure applied to dual-energy CT projection data. Material decomposition is often done using pre-computed lookup tables (LUTs) for mapping input projection data, acquired with particular X-ray source parameters, to material data values. However, the X-ray source parameters can vary over the course of a scan, making the results inaccurate. Embodiments are based on determining in advance a plurality of sets of basis LUTs for each of a plurality of different possible ranges of values over which the X-ray source parameter may vary during a scan. The basis LUTs in each set are devised as being LUTs which represent the majority contribution to the overall material decomposition function for the time-varying energy spectrum.

A first and a second image are reconstructed using the first and the second subset of data, respectively. A second pass artefact reduction method is performed using the second image as input image of the second pass artefact reduction method, thereby reducing artefacts in the first image.
