[Computerized cephalometric analysis in clinical use].

Abstract

In making a computerized cephalometric analysis, first the film should be traced, and the landmarks pricked and manually digitalized into an X-Y coordinate system. The computer's analysis program registers for the landmarks, automatically calculates the angles and line distances, and then compares these values to the norms. The computer can also print out the measurements and draw a computer-produced graph on request. Such a procedure is convenient and yields more accurate results. The most common mistake, picking in the wrong sequence, can be controlled by carefully inspecting the computer-produced graph.
