1. A method for determining a dose-related recording parameter for an examination process for a recording of a timed series of x-ray images as an x-ray image dataset of a patient at an x-ray device, the method comprising:
displaying, by a display device, a plurality of x-ray image datasets corresponding to different recording parameters and/or having different image contents described by image content parameters;
recording, by the x-ray device for each x-ray image dataset, at least one measured value describing a competency value based on an interaction of a user with an operating device assigned to the display device, wherein the competency value describes a user-specific or user group-specific user competency in respect of an evaluation of the timed series of x-ray images by the user;
automatically regulating, by a control device of the x-ray device, a radiation dose given to the patient during the examination process by determining a competency relationship describing a recording parameter-dependent competency value based on the measured values and determining a dose-minimizing value for the dose-related recording parameter for the examination process using the competency relationship; and
conducting, by the x-ray device, the examination process of the patient using the dose-minimizing value, wherein the radiation dose provides a reduced dose to the patient and generates user-specific or group-specific x-ray images in comparison to a similar examination process of the patient without a process of determining the competency relationship,
wherein the user is given a same evaluation task for all x-ray image datasets of the plurality of x-ray image datasets,
wherein the operating device receives user-side solution data from the user, and
wherein discovery of a target object is set as the evaluation task and/or a discovery time until the target object is discovered in the x-ray image dataset and/or an error rate are used as the competency value.
