1. A method of identifying anatomical structures in a patient, the method comprising:

  • acquiring an image of the patient, the image comprising a set of image elements;

    segmenting the image to categorize at least some image elements according to their substance;

    aligning the segmented image to an anatomical atlas;

    computing the probability that the categorization of the image elements is correct;

    resegmenting the image emphasizing image elements based on their probabilities; and

    developing an anatomical mesh representing an anatomical structure, the anatomical mesh having a surface, and fitting the anatomical mesh to the segmented image, wherein the anatomical mesh has vertices, and wherein the fitting the anatomical mesh to the segmented image is based on the probabilities of the image elements near the vertices.
