1. A method for using a computer system to automatically determine a transfer function for use with a 3D model, comprising the steps of:
storing a plurality of histograms in a database, each one of said histograms derived from one or more associated medical scans of a particular anatomical feature of a respective one of a plurality of different patients;
storing a plurality of transfer functions in the database, each one of said transfer functions being associated with a respective one of said plurality of histograms;
generating a current histogram from a specific medical scan of the particular anatomical feature of a particular patient using the computer system;
the computer system automatically comparing the current histogram to each one of said plurality of histograms to determine if one of said plurality of histograms is sufficiently similar to the current histogram;
if it was determined that one of said plurality of histograms is sufficiently similar to the current histogram, select the transfer function associated with the one of said plurality of histograms for preparing a model of the particular anatomical feature; and
if it was determined that none of said plurality of histograms was sufficiently similar to the current histogram, generate a new transfer function for preparing a 3D model of the particular anatomical feature.
