Abstract

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.
