A study on three-dimensional visualization of craniofacial anatomic structures

Objective:To achieve three-dimensional visualization and quantitative analyses of craniofacial structures. Methods:A versatile software package written in visual C ++ language has been developed, which consist of several functional modules including three-dimensional reconstruction , 3-D measurement , and electronic anatomy etc . By means of the comprehensive software package , the polygon-oriented surface rendering algorithm was adopted to implement 3-D volume digital data of craniofacial skeletal and soft-tissue structures. Results: The 3-D stereo models of craniofacial soft-tissue and osseous-tissue were retrieved from a series of 2-D CT slices. With rotating of these 3-D visual models , the anatomic structures could be observed and analyzed from different viewpoints . The arbitary cross-section and partial structure could be displayed and manipulated on the 3-D visual models . Conclusions:The aforementioned microcomputer software system provides novel technique of qualitative and quantitative diagnoses and analyses for craniofacial surgery . The electronic anatomy of craniofacial morphology was realized , which provide useful methods and stereoscopic models for researches of anatomy , anthropology , medical aesthetics , as well as medical education .
