description A computer-implemented method for providing a three-dimensional (3D) results data set includes: acquiring projection maps of an object under examination which are captured from various projection directions by a medical X-ray device; providing an initial projection matrix based on a static model of the X-ray device; providing a further projection matrix by applying a trained function to input data, wherein the input data is based on the initial projection matrix and the projection maps, wherein at least one parameter of the trained function is adapted based on an image quality metric and/or a consistency metric, and wherein the further projection matrix is provided as output data of the trained function; and providing the 3D results data set through reconstruction from the projection maps by the further projection matrix.
