Abstract: A medical device for treating an associated patient includes an electronic processing device configured to receive ventilation waveform data during mechanical ventilation of the associated patient and to perform a patient-ventilator asynchrony monitoring method including detecting initial patient-ventilator asynchrony events during a training period of the mechanical ventilation by analysis of measurements of the associated patient acquired during the training period; training a machine learning (ML) component to analyze ventilation waveform data to detect patient-ventilator asynchrony events using the ventilation waveform data received during the training period with labels indicating the initial patient-ventilator asynchrony events; applying the patient-specific ML component to the ventilation waveform data received after the training period to detect patient-ventilator asynchrony events occurring after the training period; and a display device configured to display an indication of patient-ventilator asynchrony events detected by the applying of the patient-specific ML component.

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.

Abstract: An active marker device (100) is introducible into a human tissue and for tracking a region of interest of a human body. The active marker device includes a light source (101) for emitting light such that the emitted light can be detected by an optical sensor. In this way, the active marker device and/or the region of interest can be tracked by a tracking system including the optical sensor. The active marker device (100) also includes a switch (102) for turning the light source on and off and for operating the light source in a pulsed mode.

Abstract: A method of a virtual X-ray colonoscopy includes scanning (204) a dark-field contrast (144) insufflated colon lumen (140) with an X-ray scanner (110) configured for dark-field-contrast, which generates dark-field-contrasted projection data and attenuation projection data. The dark-field-contrasted projection data and the attenuation projection data are reconstructed (206) into one or more dark-field-contrasted images (148).

Abstract: An X-ray imaging apparatus with an interferometer (IF) and an X-ray detector (D). A footprint of the X-ray detector (D) is larger than a footprint of the interferometer (IF). The interferometer is moved in scan motion across the detector (D) whilst the detector (D) remains stationary. Preferably the detector is a 2D full field detector.

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: A calibration method and corresponding object for calibrating an X-ray imaging system with respect to dark field imaging is disclosed. The calibration object (1) generically comprises a plurality of sections (10, 20), wherein at least a part of the sections comprises two different materials, respectively. One material (101, 201) in a corresponding section leads to attenuation of passing X-ray beams and the other material (102, 202) is a dark field active material leading to small-angle scattering signals of incident X-rays. The ratio of the two materials in one section varies from section to section. The calibration object can be used to calibrate an X-ray imaging system with respect to a non-linear behavior of the dark field visibility.

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.
