A computer-implemented method is for determining at least one main acquisition parameter determining a dose of x-rays to be emitted from an x-ray emitter during image acquisition using an x-ray emitter and an x-ray detector. A first image data of a first preparatory image is evaluated to determine if a repeat condition is fulfilled and/or to determine the main acquisition parameter and/or at least one second preparatory acquisition parameter. The first preparatory image is acquired by the x-ray detector using at least one first preparatory acquisition parameter to control the x-ray emitter. In all cases or when the repeat condition is fulfilled, the main acquisition parameter is determined depending on second image data of a second preparatory image, acquired by the x-ray detector after the first preparatory image while at least one second preparatory acquisition parameter is used to control the x-ray emitter.

A device for improving the filter effect of a filter connected up between an electrical energy source and a source of interference is provided. The filter is configured to feed back interference transients from ground to an input of the source of interference generating the interference transients. The device includes a measuring device for determining a leakage current flowing through the filter and a final control element configured to modify a limit frequency of the filter such that the leakage current through the filter is damped to below a predefined level if the measuring device detects the leakage current.
