Method for detecting the exact contour of targeted treatment areas, in particular, the external contour

Abstract

A method for mapping surgical target site contours precisely, especially the outer contour thereof, comprises the following steps: producing a plane slice image through the surgery site in the region of the surgery target whereby the plane of the slice image is located substantially perpendicular to a a plane of symmetry of the surgery target site; assigning the images split by the plane of symmetry, more particularly by mirrowing at the plane of symmetry; and establishing the difference in the image contents between the assigned split images and processing the resulting information to determine the location of the contour of the surgery target site, especially the outer contour thereof in the plane of the slice image.
