A method is for providing a resultant image dataset for a volume of interest. In an embodiment, an X-ray image dataset for the volume of interest is received, having a first noise level. A trained generator function is received, a parameter of which is based on a first and a second training image dataset for a training volume of interest. The first and the second training image dataset include a first training noise level. In addition, a resultant image dataset for the volume of interest is determined by applying the trained generator function to input data comprising the X-ray image dataset, the resultant image dataset has a second noise level less than the first noise level. In addition, the resultant image dataset is provided. As such, a higher noise level can be accepted and/or a lower X-ray dose can be used in the acquisition of the X-ray image dataset.
