The system not only realizes the automation from landmark location to parameter measurement on cephalogram, but also makes the diagnostic design of preoperation of orthognathic surgery quantitive. Compared with the manual prediction, it provides a new method to make the diagnosis and treatment for deto maxillofacial deformities more accurate. It is more significant to clinical application and scientific research.展开更多
