Abstract

A method for localization of surgical target sites in the region of soft body parts, including the following steps: applying a number of artificial landmarks to the body part permitting sensing by a referencing system; referencing the surgical target site location relative to a landmark arrangement in a first position of the body part; sensing a new landmark arrangement in a changed second position of the soft body part; and mapping the dislocation or new location of the surgical target site by means of the information as to the dislocation or new arrangement of the landmarks.
