Study of computer-assisted Delaire cephalometric analysis system

目的实现Delaire头影测量分析法在WinCeph8.0软件中的计算机辅助分析,减少该法手工测量过于复杂、工作量大的不足。方法基于Delaire头影测量分析法的原理和WinCeph8.0中的编程模块,通过自定义标记点、辅助线,编写相关测量、分析程序,构建计算机辅助Delaire头影测量分析法,并对Delaire计算机辅助测量和手工测量结果做配对t检验和离散性分析。结果计算机辅助Delaire头影测量分析法能方便、快速、准确地进行标记点、辅助线描记,自动完成数据的测量计算,显示分析结果。统计分析显示Delaire计算机辅助测量较手工测量准确性更高,适合临床应用。结论本研究为Delaire头影测量分析法提供了一个方便、快捷、准确的计算机辅助测量分析平台,具有较好的临床推广价值。

Objective The purpose of this study was to establish the computer-assisted Delaire cephalometric analysis system with WinCeph8.0 in order to simplify the procedure of manual Delaire eephalometrie analysis. Methods On the basis of the theory of Delaire eephalometrie analysis and the program module of WinCeph8.0, the landmark points and the auxiliary line were defined, the measurement and analysis program were written, then the computer-assisted Delaire eephalometrie analysis system was established. Paired t-test and dispersion analysis of the computer-assisted and manual measurements were taken. Results Computer-assisted Delaire eephalometric analysis system was convenient and accurate to trace the landmark points and the auxiliary line. It was able to proceed the measurement and calculation automatically and display the analysis results. Statistical analysis showed that computerassisted analysis was more accurate than manual analysis. Conclusion This study provided a convenient, simplified, accurate eomputer-assistod analysis platform for Delaire cephalometrie analysis which facilitated its clinical application.
