1. A method for determining at least one value of at least one recording parameter for a recording of an X-ray image of a patient positioned on an examination table, comprising:
scanning, in a contactless manner, at least part of a surface of the patient using at least one electromagnetic sensor before the recording the X-ray image, the at least one electromagnetic sensor being a stereo camera, a triangulation system or a range measuring system;
calculating a three-dimensional contour of the scanned surface using information from the at least one electromagnetic sensor;
identifying at least one anatomic landmark of the patient using the three-dimensional contour;
determining a position of the at least one anatomic landmark in a coordinate system of the examination table; and
determining the at least one value of the at least one recording parameter using the determined position of the at least one anatomic landmark, the at least one recording parameter includes a reconstruction parameter, the determining the at least one value includes,
determining a reconstruction center based on the three-dimensional contour and the determined position of the at least one anatomic landmark.
