ABSTRACT:
In an x-ray diagnostics apparatus having a scattered radiation grid moveable in a plane, the movement of the scattered radiation grid ensues via a tumbling or wobble bearing arranged between a rotating drive and the scattered radiation grid. An advantage of this arrangement is that relatively long standstill times during the reversal of the grid movement are reduced. Moreover, the tumbling or wobble bearing can be economically manufactured and is less structurally complicated than a lever articulation.
