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.

Abstract: In an X-ray system and method to determine the effective skin input dose in x-ray examinations, the skin input dose is obtained by dividing the measured dose area product by the exposed skin input area, which is calculated from the exposed area in the film or image intensifier plane, geometric data of the x-ray system, and the thickness of the body part of the patient to be examined. The water equivalent determined from the setting values for the irradiation is used as the value for the thickness of the body part to be examined.
