Abstract:
1. An X-ray system comprising: at least one component in the X-ray system that is displaceable or pivotable along at least one traverse path to at least one predeterminable locking position; a braking means, wherein the braking means comprises an electromagnetic brake that is (i) active in a de-energized state and (ii) released by feeding current to the electromagnetic brake; and a control unit configured for sensing an instantaneous speed of the component when displaced or pivoted along the traverse path within at least one predeterminable window of the traverse path, the at least one predeterminable window being defined by two positions of the traverse path situated laterally from and disposed about the at least one predeterminable locking position, the at least one predeterminable window having a widthwise size selected as a function of a mass of the at least one component, the control unit further configured for activating the braking means in response to (i) the speed within the predeterminable window being below a predeterminable limiting value and (ii) the component having reached (a) the locking position or (b) shortly before the locking position.
