A method for creating a model of a part of the anatomy from the scan data
of several subjects is described. The method comprises the steps of
collecting scan data; applying a feature detector to the scan data;
converted the output of the feature detector into a common reference
system; and accumulating the converted data to generate the model. It is
therefore possible for the method to generate a model from the scan data
of several subjects automatically. The method may also include an
optional step of receiving user input to select which of the accumulated
data should be included in the final model. This user input requires much
less effort than manual contouring and is substantially independent of
the number of subjects used to create the model.
