A method of tracing the likely contour of an anatomical element (S, C) in a sectional image of an anatomical site, the image being composed of pixels (Pi) having different intensities, the method comprising the following steps: a) forming columns (K) of pixels (Pi) passing through the anatomical element (S, C), b) assigning each pixel (Pi) a pixel score representing the probability of the pixel being situated on the contour of the anatomical element (S, C), c) constituting a matrix of pixel scores from a plurality of columns (K) of pixels and defining numerous continuous paths of pixels, each passing through a single pixel of each column, d) assigning each continuous path a path score that is a function of the scores of the pixels constituting the continuous path, e) selecting from a set of continuous paths the path that has the best path score, that path representing the likely contour of the anatomical element.
