Abstract: A monitoring device for maintenance prediction for a medical imaging apparatus and a related method are described. First and second data sets of parameters of the medical imaging apparatus are measured over respective first and second periods by a data processing unit, one data set for each period. The second data set comprises data samples selected based on a trigger point. Operation modes of the medical imaging apparatus are identified based on the first set and the selected data samples. It is analysed whether there are corresponding operation modes, one operation mode for each data set. In a validation step it is validated whether the measured parameters in the first set and the selected data samples differ. Based on the outcome of the validation step, a feedback signal is issued, including maintenance prediction information.

Abstract: An improved X-ray imaging system. The system comprises an X-Ray radiation source configured to emit an X-ray beam towards an object to be imaged and an X- ray detector configured to detect X-rays which have passed through the object. It further comprises a reconstruction processing means configured to reconstruct an image of the object based on the detected X-rays, wherein the reconstruction processing means is further configured to determining presence of at least one foreign object located in the object or located between a surface of the object and the X-Ray radiation source and/or the X-ray detector, obtaining a three-dimensional profile of the determined foreign object from a server-based foreign object database, and reconstructing an image of the object by acquiring a plurality of projection images of the object from the X-ray detector and reducing impact on image quality of an artefact that can be caused by the foreign object in the image of the object based on at least the obtained three-dimensional profile of the foreign object.

Abstract: An X-ray source for emitting an X-ray beam is proposed. The X-ray source comprises an anode and an emitter arrangement comprising a cathode for emitting an electron beam towards the anode and an electron optics for focusing the electron beam at a focal spot on the anode. The X-ray source further comprises a controller configured to determine a switching action of the emitter arrangement and to actuate the emitter arrangement to perform the switching action, the switching action being associated with a change of at least one of a position of the focal spot on the anode, a size of the focal spot, and a shape of the focal spot. The controller is further configured to predict before the switching action is performed, based on the determined switching action, the size and the shape of the focal spot expected after the switching action. Further, the controller is configured to actuate the electron optics to compensate for a change of the size and the shape of the focal spot induced by the switching action.

An object is positioned (240) between the first grating and the third grating. At least one of the three gratings has a pitch attribute of having a constant grating pitch. At least one of the three gratings has a pitch attribute of having a varying grating pitch. Both gratings of an adjacent pair of gratings are bent such that a distance between the two adjacent gratings is constant as a function of fan angle. Both gratings of the adjacent pair of gratings that are bent have the same pitch attribute. An X-ray detector detects (250) at least some of the X-rays transmitted by the three gratings and the object.

Abstract: Hydrodynamic bearings exploit the properties of pumping action in a fluid to support a bearing load. Conventionally, the pumping action is provided by grooved surfaces in a bearing surface of the bearing. The provision of grooves leads to functional and practical problems, though. The action of grooves on a lubrication material leads inevitably to shear stress being exerted in the fluid. This has a detrimental effect on the load performance of a hydrodynamic bearing. In practical terms, the accurate manufacture of grooves is onerous. This application discusses a way of producing a hydrodynamic bearing using a portion of a bearing surface with an interleaved pattern of materials, wherein the materials have alternate high and low (or zero) fluid slip characteristics. The varying fluid slip characteristic of the surface induces a pumping effect analogous to that provided by a grooved surface.

Abstract: The present invention relates to X-ray imaging. In order to improve the throughout of an X-ray imaging system, an apparatus is provided for managing an imaging workflow of an X-ray imaging system for an upcoming imaging sequence. The apparatus comprises an input unit, a processing unit, and an output unit. The input unit is configured to receive data including (i) a current temperature profile of an X-ray anode inside a tube housing of the X-ray imaging system, (ii) information about a heat capability and a cooling rate of the X-ray anode, (iii) information about a heat capability and a cooling rate of the tube housing, (iv) information about a current operation condition of the X-ray imaging system, and (v) information about a planned operation condition of the X-ray imaging system for the upcoming imaging sequence, wherein the planned operation condition comprises a sequence of planned scans, each planned scan being associated with a respective set of planned scan parameters. The processing unit is configured to determine, based on the received data, an estimated temperature profile of the X-ray anode under the planned operation condition for the upcoming imaging sequence. The processing unit is configured to compare the estimated temperature profile of the X-ray anode with a maximum allowable hardware temperature of the X-ray anode. In response to the determination that the estimated temperature profile is greater than or equal to the maximum allowable hardware temperature of the X-ray anode, the processing unit is configured to modify the planned operation condition such that the estimated temperature profile of the X-ray anode under the modified planned operation condition is less than the maximum allowable hardware temperature of the X-ray anode. The modified planned operation condition comprises a change of the sequence of planned scans and/or a change of the set of planned scan parameters for one or more planned scans. The output unit is configured to provide the modified planned operation condition for the upcoming imaging sequence.
