Abstract: A computer-implemented method for generating training data for training an algorithm for estimating positioning variances in an imaging apparatus of an x-ray imaging system is provided. The method includes predetermining target positioning data for the imaging apparatus and calculating faulty positioning data, wherein the faulty positioning data deviates from the target positioning data by at least one predetermined positioning variance. An imaging method is simulated, in order to generate two or more simulated x-ray recordings, wherein a positioning of the imaging apparatus is simulated in accordance with the faulty positioning data. An annotated training data record is generated and stored, wherein the training data record contains two or more simulated x-ray recordings and at least one positioning variance as an annotation of the two or more simulated x-ray recordings.

Abstract: A couch panel for a patient couch for a medical imaging method is disclosed. The couch panel is of single-shell design, beads are formed in the longitudinal direction of the couch panel, wherein the number and the shape of the beads are chosen such that the couch panel has a predefinable geometric moment of inertia. The two longitudinally extending edges of the couch panel are bent upward. This is advantageous because of the cost-effective production of a couch panel and, in the case of X-ray imaging, in the low radiation absorption. A patient couch having a couch panel of this kind is likewise disclosed.

Abstract: A method automatically determines a weight of a patient lying on a tabletop of a patient positioning device. A motorized movement of the tabletop along at least one predeterminable axis sets the tabletop in an oscillation via an elastic drive train element, and the patient's weight is determined from a determined oscillation frequency. Therefore, the weight of a patient lying on a patient positioning device can be determined in a simple manner.

Abstract: An examination or treatment facility includes a C-arm, movable along a circular path relative to a bracket supporting the arm. In an embodiment, the C-arm includes a bent carrier with a U-shaped cross-section, movable on a guidance facility provided on the bracket. The carrier is accommodated in a covering part with a C-shaped cross-section. The covering part includes its open side directed toward the guidance facility and is closed via flexible sealing elements, movable apart by the guidance facility.

Abstract: An apparatus for movably suspending an x-ray grid. The apparatus has a carrier module, in or on which the x-ray grid is arranged, and a linkage. The linkage is configured to rotate the carrier module about an axis which is vertical to the x-ray grid and/or to translate the carrier module in the plane of the x-ray grid. An x-ray arrangement has an x-ray emitter, an x-ray detector and one or more apparatus for suspending the x-ray grid between the emitter and detector. The apparatus provides for play-free kinematics which is more cost-effective than the use of known precision drives.

Abstract: A carrying device is disclosed for a retaining device for an X-ray tube assembly and an X-ray detector of an X-ray system. The carrying device includes a suspension device; a first carrier element arranged on the suspension device; a second carrier element; a first connecting element, the second carrier element being connected to the first carrier element via the first connecting element; a third carrier element connectable to the retaining device; and a second connecting element, the third carrier element being connected to the second carrier element via the second connecting element. In an embodiment, the first connecting element and/or the second connecting element include a revolute joint. Further, the distance between the suspension device and the first connecting element is variable via the first carrier element, and the distance between the first connecting element and the second connecting element is variable via the second carrier element.

Abstract: A device for suspending an x-ray grid has a first rotating frame which can be rotated about a first axis. The x-ray grid is disposed in or on the rotating frame. Two first flexible hinge elements are connected to the first rotating frame and are aligned along the first axis. The first rotating frame is reversibly rotatable about the first axis. An x-ray arrangement has one or more such suspension devices between an x-ray emitter and an x-ray detector. The articulated flexible elements of the novel device are completely play-free and significantly more cost-effective that separate hinges.

Abstract: The disclosure provides a device having a C-arm, the C-arm including a main body of which the cross-sectional profile is formed as a double H, an outer wall, an inner wall and two side walls of the main body forming a rectangular cavity.
