METHOD AND SYSTEM FOR USER INTERACTION IN 3-D CEPHALOMETRIC ANALYSIS

摘要

A method for 3-D cephalometric analysis acquires reconstructed volume image data from a computed tomographic scan of a patient's head. The acquired volume image data simultaneously displays from at least a first 2-D view and a second 2-D view. For an anatomical feature of the head, an operator instruction positions a reference mark corresponding to the feature on either the first or the second displayed 2-D view and the reference mark displays on each of the at least first and second displayed 2-D views. In at least the first and second displayed 2-D views, one or more connecting lines display between two or more of the positioned reference marks. One or more cephalometric parameters are derived according to the positioned reference marks, the derived parameters are displayed.

主权项

1. A method for 3-D cephalometric analysis, the method executed at least in part by a computer, comprising:
acquiring reconstructed volume image data from a computed tomographic scan of a patient's head; simultaneously displaying the acquired volume image data from at least a first 2-D view and a second 2-D view; for each of a plurality of anatomical features of the head:
(i) accessing an operator instruction that positions a reference mark corresponding to the feature on either the first or the second displayed 2-D view;(ii) displaying the reference mark on each of the at least first and second displayed 2-D views; displaying, in at least the first and second displayed 2-D views, one or more connecting lines between two or more of the positioned reference marks; deriving at least one cephalometric parameter according to the plurality of the positioned reference marks; and displaying, storing, or transmitting the at least one derived cephalometric parameter.
