The invention concerns a medical imaging station including segmentation means for segmenting at least one imaged object in an image having gray levels, by propagating an edge from at least one initial point positioned in the image on the imaged object. The speed of propagation of the edge depends on said gray levels at each point referred to as a current point and the segmentation means segmenting the image between the points over which the edge passes and the points over which the edge does not pass. According to the invention, the edge propagation means are coupled with means of automatically detecting an emergence of the propagation edge from the imaged object at a current point. Means of locally fixing the speed of propagation at zero at this current point are activated in the event of detection of an emergence of the propagation edge.

The invention relates to an image processing method for processing an image representing a tubular structure having walls, comprising steps for determining a flight path (EP) inside this tubular structure between a first and a second predetermined end points, said flight path being both the shortest path between said end points and the farthest from the structure walls (NB ). Said steps may comprise locating the structure wall points, determining a surface at a predetermined constant distance from said wall points, inside the structure, for forming a central region (CR), and determining, in said central region, the shortest path (EP) between the first and second end points.
