1. A computer-implemented method comprising:
based on an input dataset defining an input image, determining a reconstructed image using a reconstruction algorithm, and
executing a data-consistency operation enforcing consistency between the input image and the reconstructed image,
wherein the data-consistency operation determines, for multiple K-space positions at which the input dataset comprises respective source data, a contribution of respective K-space values associated with the input dataset to a K-space representation of the reconstructed image.
