Abstract: A skull clamping device for fixing and aligning a head of a patient for a medical intervention includes a first ring element and a second ring element arranged concentrically. The second ring element is arranged within the first ring element and is connected hereto by a second axis, about which the second ring element is mounted rotatably within the first ring element. The first ring element is mounted rotatably about a first axis that is orthogonal to the second axis. The skull clamping device also includes a motor-driven drive that drives rotation of the first ring element and/or the second ring element about the respective axis, at least two pins arranged in an innermost ring element, two telescope bars that hold the first ring element and the second ring element, and a control unit for the motor-driven drive.

Abstract: A method is provided for automatically determining a suitable angulation or inclination of a recording system during a navigation of a guide wire through a vascular system of a patient from a vessel into a branch of the vessel. The method includes recording a sequence of live X-ray images of the guide wire and presenting the X-ray images on a display unit. A first virtual tangent is applied to a first section of the guide wire, and a second virtual tangent is applied to a second section of the guide wire on the X-ray images. A point of intersection of the virtual tangents is determined on the X-ray images, and a triangle is determined. An area of the triangle is determined, and the suitable angulation or inclination of the recording system is determined by maximizing the area of the triangle by movement of the recording system.

Abstract: A skull clamping device for fixing and aligning a head of a patient for a medical intervention includes at least two ring elements arranged concentrically. A second ring element of the two ring elements is arranged within a first ring element of the two ring elements and is connected hereto by a second axis, about which the second ring element is mounted rotatably within the first ring element. The first ring element, which is outer relative to the second ring element, is mounted rotatably about a first axis that is orthogonal to the second axis. The skull clamping device also includes at least one motor-driven drive that drives the rotation of one or more of the at least two ring elements about the respective axis, at least two pins that are arranged in an innermost ring element of the at least two ring elements and are embodied to fix a head of a patient, two telescope bars that hold the at least two ring elements, and a control unit for the motor-driven actuation of the at least one motor-driven drive.

Abstract: System and methods are provided for an X-ray assembly including at least two X-ray facilities each with a control facility and a recording assembly including an X-ray tube and an X-ray detector. At least one of the X-ray facilities is a mobile X-ray facility with a mobile carrier carrying the recording assembly. The control facility of least one of the at least one mobile X-ray facility is configured to control the image recording operation of the respective X-ray facility using control data received from another control facility via a communication connection and/or to transfer at least one recorded image dataset to at least one further control facility via the communication connection.

Abstract: A performance evaluation system has a computer for displaying the production performance of a machine compared with the production performance of other machines. The machines a connected via a network link to a performance comparison computer. The invention is set up such that comparison data from the performance comparison computer are displayed at least to the operator of a machine via the display of the computer for displaying the production performance.

Abstract: A method and an associated arrangement for starting up a medical engineering system via a data transmission link are provided. The method includes storing, in advance, at least one switch-on time for the medical engineering system in a spatially remote central unit via the data transmission link. The method also includes switching-on the medical engineering system by the central unit via the data transmission link at the at least one stored switch-on time.
