Providing a result image data set

A provision system for providing a result image data set, the provision system comprising:

• an interface configured to receive an input image data set of a first examination volume, and to provide a result image data set of the first examination volume;
• and
• an arithmetic unit, at least one of the interface or the arithmetic unit being configured to receive or determine a result image parameter, and the arithmetic unit being configured to determine the result image data set of the first examination volume by application of a trained generator function to input data, a parameter of the trained generator function being based on a Generative Adversarial (GA) algorithm, the input data being based on the input image data set, the result image parameter, and the result image parameter relates to one or more properties of the result image data set, the one or more properties including
• an X-ray dose of the result image data set,
• noise level of the result image data set, and
• at least one of an X-ray source or an X-ray detector corresponding to the result image data set, and an input image parameter, the input image parameter relating to a property of the input image data set, the input data being based on the input image parameter, wherein
• the input image data set is an X-ray image data set of the first examination volume.
