1. A method of augmenting a two-dimensional medical image showing at least a part of an associated patient, the method comprising:
acquiring a spatial position of an associated medical instrument;
calculating the two-dimensional medical image from a three-dimensional medical image dataset of the associated patient based on the acquired spatial position of the associated medical instrument;
overlaying a representation of the associated medical instrument over the two-dimensional medical image;
finding at least one feature point along a detection line defined relative to the associated medical instrument in the two-dimensional medical image based on the acquired spatial position of the associated medical instrument;
calculating a numerical value representing one or more of a length, an area, and/or an angle from a position of the at least one feature point in the two-dimensional medical image; and
overlaying the calculated numerical value over the two-dimensional medical image.
