【Abstract】 Objective In an attempt to establish a computer three-dimensional image reconstruction method of the craniofacial morphological structure. Methods Craniofacial morphology was obtained in a sample of 20 men and 20 women. The method of 3D reconstruction by multi-slice helical CT data was described. Results The new structure can be resectioned by computer in various planes to expose any given structure for study. By altering the viewing axis the new structure relationships may be observed and analyzed. Conclusion The three-dimensionalre reconstrucing method can offer a new means to study the craniofacial morphology characteristics. The technique offer a preservative method of morphological date file.更多还原
