Abstract: An expanded diagnostic NMR installation with operating functionality contains an NMR imaging apparatus with a patient bed for transporting a patient into an imaging volume of the NMR imaging apparatus. An operating column for receiving the patient bed is arranged next to the NMR imaging apparatus at a fixed distance therefrom along the longitudinal direction of motion of the patient bed. The operating column contains a swinging mechanism for rotating or pivoting the patient bed around a vertical axis.

Abstract: A control unit for a medical device has an actuation part and an electrical signal output that, due to an actuation of the actuation part, emits a control signal for a control computer of the medical device. The actuation device is secured to a work chair at the level of the heel of the foot of a person on the work chair.

Abstract: An x-ray tube, in addition to an anode and a cathode arrangement, has first and second electrodes that are located in an evacuated housing provided with a beam exit window. The anode and the first electrode are at potentials that are positive in comparison to the potentials of the cathode arrangement and the second electrode. Further, the first and the second electrode are arranged lying opposite one another such that secondary electrons emanating from the anode must pass through the space located between the first and the second electrode in order to proceed to the beam exit window. These secondary electrons are thus substantially all prevented from reaching the beam exit window, thereby avoiding excessive heating of the beam exit window.
