1. A method of generating a view of a jaw, the method comprising: obtaining a tomographic dataset of a volume including at least part of the jaw; identifying, in the tomographic dataset, inner and outer surfaces of the jaw without requiring input from a human operator; selecting data for a region with boundaries related to the identified inner and outer surfaces; generating from the selected data a panoramic image in which one element of the panoramic image represents a generally radial line through the slice parallel to a predetermined plane; and displaying the panoramic image, wherein the selected data from which the panoramic image is generated are the data for a region between the inner and outer generated surfaces excluding data in layers along the inner and outer surfaces, and the thickness of the excluded layers along the inner and outer surfaces is a constant proportion of the distance between the identified inner and outer surfaces, measured along generally radial lines.
