1. A computer-implemented method for determining at least one main acquisition parameter determining a dose of x-rays to be emitted from an x-ray emitter during a main image acquisition using the x-ray emitter and an x-ray detector for imaging an object, the computer-implemented method comprising:
evaluating first image data of a first preparatory image to at least one of
determine whether or not a repeat condition is fulfilled,
determine the at least one main acquisition parameter, and
determine at least one second preparatory acquisition parameter, the first preparatory image being an image acquired by the x-ray detector using at least one first preparatory acquisition parameter to control the x-ray emitter;
determining, at least one of in all cases or only when the repeat condition is fulfilled, the at least one main acquisition parameter depending on second image data of a second preparatory image, acquired by the x-ray detector after the first preparatory image while the at least one second preparatory acquisition parameter is used to control the x-ray emitter; and
evaluating the second image data to determine whether a further repeat condition is fulfilled;
wherein the at least one main acquisition parameter depends on third image data of a third preparatory image when the further repeat condition is fulfilled, the third preparatory image being an image acquired by the x-ray detector after the second preparatory image while at least one third preparatory acquisition parameter is used to control the x-ray emitter.
