Abstract

In a method of image support for a person carrying out a minimally invasive procedure with an instrument in a procedure site of a patient, one two-dimensional X-ray image respectively of the procedure site is recorded by an X-ray apparatus in at least two recording geometries implementing different projection directions and chosen specific to the procedure, in particular by the person. A three-dimensional model data set of the procedure region is reconstructed by iterative reconstruction from the X-ray images. At least one two-dimensional supporting image corresponding to one of the recording geometries is determined by incorporating at least one item of further information by re-projection of the model data set supplemented by the further information and is displayed for the user.
