1. A method for generating a cephalometric analysis of an orthodontic patient, comprising: receiving a sequence of images each corresponding to a specific anatomical plane of the orthodontic patient; deriving a volumetric representation of the orthodontic patient from a combination of the sequence of the images; receiving one or more markers associated with particular anatomical landmarks of the orthodontic patient according to a predefined analysis method, the markers being defined by a set of coordinate values and designated via an interactive user interface to a two-dimensional representation derived from the volumetric representation; generating connectors between one or more selected ones of the markers in accordance with the predefined analysis method; and overlaying a visual representation of the markers and the connectors on the volumetric representation.
