Method for cephalometric analysis

A method for 3-D cephalometric analysis of a patient, the method executed at least in part on a computer processor and comprising:

• displaying reconstructed volume image data from a computed tomographic scan of a patient's head from at least a first 2-D view or a 3-D view;
• accepting an operator instruction that positions and displays at least one reference mark on the at least the first displayed 2-D view or the 3-D view;
• segmenting one or more dentition elements within the mouth of the patient;
• computing and displaying a plurality of anatomical cephalometric parameters and a plurality of derived cephalometric parameters for the patient according to data from the at least one reference mark and the one or more segmented dentition elements;
• computing, using the computed cephalometric parameters, one or more results indicative of maxillofacial asymmetry;
• and
• energizing a graphical or text display to show the computed results indicative of maxillofacial asymmetry, where the display includes:
• a first plurality of entries representing different selected maxillofacial asymmetric anterior posterior relations, maxillofacial asymmetric vertical relations and maxillofacial asymmetric transverse relations,
• a second plurality of entries representing synthesized maxillofacial asymmetric cumulative anterior posterior condition, synthesized maxillofacial asymmetric cumulative vertical condition, and synthesized maxillofacial asymmetric cumulative transverse condition, which are generated using the first plurality of entries, and
• a third entry representing a combination of the synthesized maxillofacial asymmetric cumulative anterior posterior condition, the synthesized maxillofacial asymmetric cumulative vertical condition, and the synthesized maxillofacial asymmetric cumulative transverse condition.
