Abstract: A system (IPS) and related method for image processing, in particular dark-field or phase contrast imaging to reduce motion artifacts. The system comprises an input interface (IN) for receiving a series of projection images (π) acquired by an X-ray imaging apparatus (XI) of an object (OB) for a given projection direction, the imaging apparatus (XI) configured for phase-contrast and/or dark-field imaging A phase-contrast and/or dark-field image generator (IGEN) applies an image generation algorithm to compute a first image based on the series the projection images (π). A motion artifact detector (MD) detects a motion artifact in the first image. A combiner (Σ) combines, if a motion artifact is so detected, a part of the first image with a part of at least one auxiliary image to obtain a combined image. The auxiliary image was previously computed by a gated application of the image generation algorithm in respect of a subset of the series of the projection images (π). The combined image may be output at an output interface (OUT) as a motion artifact reduced image.

Abstract: A system and method for indicating a desired target radiation area of a radiation beam from a phase contrast radiology system on a subject comprising a first and second light field generator to project light fields on a subject. Both light fields are decoupled from path of the radiation beam. The overlapping area of both light fields indicates the target radiation area. The light fields do not substantially match a radiation beam path.

Abstract: The invention relates to a control module for controlling an x-ray system (140) during the acquisition of step images for phase imaging. The control module comprises a step image quantity providing unit (111) for providing a step image quantity, a detector dose providing unit (112) for providing a target detector dose, an applied detector dose determination unit (113) for determining an applied detector dose absorbed by a part of the detector (144) during the acquisition of a step image, and a step image acquisition control unit (114) for controlling the x-ray imaging system (140) during the acquisition of each step image based on the applied detector dose, the target detector dose and the step image quantity. The control module allows to control the x-ray imaging system such that the target detector dose is not exceeded while at the same time ensuring a sufficient quality of the step images.

Abstract: The present invention relates to an apparatus (10) for alveoli based visualization in dark-field or phase-contrast X-ray imaging. It is described to provide (210) a dark-field or phase-contrast X-ray image of a region of interest of an object, wherein image data are represented in units of a dark-field or a phase-contrast signal. A calibration is provided (220) relating dark-field or phase-contrast signal to an alveoli index in a lung. The calibration is utilized (230) to convert the dark-field or phase-contrast X-ray image of the region of interest of the object into an alveoli based image of the region of interest of the object, wherein the image data are represented in units of the alveoli index. The alveoli based image is outputted (240).

Abstract: The present invention relates to an apparatus for X-ray imaging an object. It is described to provide (20) data relating to the detection of X-rays, wherein an X-ray detector is configured to be positioned relative to an X-ray source such that at least a part of a region between the X-ray source and the X-ray detector is an examination region for accommodating an object. An X-ray interferometer arrangement is configured to be positioned relative to the examination region. At least one X-ray dark field factor and at least one transmission factor are determined for the X-ray radiation transmitted through at least part of the object is determined. An intensity of X-ray radiation to be emitted towards the at least part of the object is controlled as a function of the determined at least one dark field factor and the determined at least one transmission factor.
