Providing adjusted recording parameters

A computer-implemented method for provision of a trained function, the computer-implemented method comprising:

• capturing spatially resolved training dose profiles for a respective real or simulated x-ray imaging scan of at least one training examination object in accordance with initial training recording parameters via a photon-counting x-ray detector, wherein
• the photon-counting x-ray detector has a plurality of photon-counting detector elements, each photon-counting detector element providing a training dose value based on a number of detected x-ray photons after an interaction between x-ray radiation and the at least one training examination object, and
• the spatially resolved training dose profiles are formed by the training dose values of the plurality of photon-counting detector elements of one or more x-ray imaging scans;
• first classifying the spatially resolved training dose profiles based on the initial training recording parameters;
• second classifying the first classified, spatially resolved, training dose profiles into conformant and deviating training dose profiles by application of a dose-aware signal quality metric to the training dose profiles within a first class, the dose-aware signal quality metric indicative of a signal quality while taking into account a respective overall dose;
• provisioning adjusted comparison recording parameters based on the initial training recording parameters of the spatially resolved training dose profiles classified as conformant;
• provisioning adjusted training recording parameters by applying the trained function to input data, wherein
• the input data is based on the initial training recording parameters and the spatially resolved training dose profiles;
• adjusting at least one parameter of the trained function based on a comparison of the adjusted training recording parameters with the adjusted comparison recording parameters;
• and
• provisioning the trained function.
