1. A method for providing a corrected dataset, the method comprising:
receiving a preoperative dataset including an image, a model, or the image and the model of an examination region of an examination subject;
receiving length information, wherein at least a part of a medical object is arranged intraoperatively in the examination region, and wherein the length information includes information relating to a length of the part of the medical object arranged in the examination region;
receiving an intraoperative dataset;
determining first positioning information relating to a virtual positioning of a predefined section of the part of the medical object arranged in the examination region based on the preoperative dataset and the length information;
receiving, determining, or receiving and determining second positioning information relating to a real positioning of the predefined section;
determining a transformation rule for minimizing a deviation between the first positioning information and the second positioning information;
generating the corrected dataset, the generating of the corrected dataset comprising applying the transformation rule to the preoperative dataset; and
providing the corrected dataset,
wherein a spatial course of the predefined section is identified in the intraoperative dataset;
wherein the intraoperative dataset includes a projection image of the examination region, and
wherein the spatial course of the predefined section is identified in the projection image using a deformation model of the medical object.
