Abstract: In order to improve three-dimensional (3D) printing a high-aspect-ratio three-dimensional metal structures, there is provided a printing method that builds a wall comprising a center part made out of a metal-containing material and left and right parts made out of a plastic material forming first and second supporting wall elements. The plastic support material may be used to enable the build-up of a high-aspect-ratio 3D structure. The proposed printing strategy may be applicable to a cost-effective 3D printing technology, such as fused deposition molding (FDM).

Abstract: The present invention relates to an apparatus for generating dual energy X-ray imaging data. It is described to position an X-ray detector 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. A grid filter is positioned (220) between the examination region and the X-ray source. The X-ray source produces (230) a focal spot on a target to produce X-rays. The X-ray source moves (240) the focal spot in a first direction across a surface of the target. The grid filter has a structure in a first orientation such that the movement of the focal spot in the first direction results in an associated change in an intensity of X-rays transmitted by the grid filter. The X-ray source moves (250) the focal spot in a second direction across the surface of the target that is orthogonal to the first direction. The grid filter has a structure in a second orientation orthogonal to the first orientation such that the movement of the focal spot in the second direction results in an associated change in an energy spectrum of X-rays transmitted by the grid filter. The X-ray detector detects (260) at least some of the X-rays transmitted by the grid filter.

Abstract: The present invention relates to a grating in X-ray imaging. In order to provide a grating with a facilitated stabilization, a grating (10) for X-ray imaging is provided that comprises a grating structure (12) with a first plurality of bar members (14) and a second plurality of gaps (16). A fixation structure (18) is arranged between the bar members to stabilize the grating bar members. The bar members are extending in a length direction (20) and in a height direction (22). The bar members are also spaced from each other by one of the gaps in a direction transverse to the height direction. The gaps are arranged in a gap direction parallel to the length direction. The fixation structure comprises a plurality of bridging web members (24) that are provided between adjacent bar members. Further, the web members are longitudinal web members that are extending in the gap direction and that are provided in an inclined manner in relation to the height direction. The inclination is provided in the gap direction.

Abstract: Systems and methods are provided for monitoring the state of an x-ray tube (100). The method comprises: receiving sensor data from a sensor array apparatus (120) positioned to observe at least part of a surface of an anode (102) of the x-ray tube; processing the received sensor data to identify and quantify surface damage to the anode; storing the identified and quantified surface damage with a time stamp; and correlating the identified and quantified surface damage to one or more usage protocols in an operational history record of the x-ray tube and used at a time corresponding the time stamp and/or used at a time in between time stamps.

Abstract: A focusing grating device (100) is described comprising a substrate (402) and a grating comprising a plurality of grating features (408) positioned on the substrate (402). The grating features (408) are positioned non-perpendicular to the substrate surface, thereby inducing a first focusing direction. The substrate (402) is curved, thereby inducing a second focusing direction, which is different from the first focusing direction. An X-ray system (300) comprising such a focusing grating device (100) as well as a method for producing such a focusing grating device (100) are also described.

Abstract: A system (SYS) and related method for imaging support. The system (SYS) comprises a stimulus delivery component (SDC) configured to cause a chemoreceptor stimulus in a patient residing in or at an imaging apparatus (IA). A response measuring component (RMC) measure a response of the patient to the stimulus, and a decision logic (DL) establishes, based on the measured response, a sedation status of the patient for the purpose of imaging the patient. An imaging operation can be modified, for instance, halted if the patient is no longer sufficiently sedated.
