应用计算机测量乳房基本尺寸的实验研究

目的 研究应用计算机辅助光学投射条纹测试技术测量乳房基本尺寸。方法 基于计算机辅助光学投射条纹测试技术基本原理和软件编程技术研制乳房尺寸测量系统，采用该系统测量塑料人体模特乳房的胸乳间距、乳头一中线间距、乳头间距、乳房基底宽度和乳头．乳房下皱襞间距等项目，并与常规的直尺测量法相比较。结果 应用该系统测量乳房尺寸具有以下优点：①非接触性测量过程；②测量速度快，患者仅需屏气0．5秒，测量总耗时大约2．5min；③测量灵敏度高达0．6mm，完全满足临床需要；④与常规的直尺测量法比较，两者的测量准确度无明显差别。结论 应用计算机辅助光学投射条纹测试技术测量乳房基本尺寸的方法是可行的和先进的。

A study of making use of computer-aided projection fringe system to measure breast dimension

OBJECTIVE: To measure breast basic dimension by using computer-aided projection fringe system. METHODS: A system has been developed for measuring breast basic dimension based on computer-aided projection fringe measurement and programming software. Plastic manikins breast's SN-N (sternal notch to nipple distance), N-ML (nipple to midline distance), N-N (internipple distance), MBW (base width of breast) and N-IMF (nipple to inframammary fold distance) are measured with this system. At the same time, these items are also measured with routine ruler. RESULTS: This study indicate that the system has some merits: (1) non-touching measurement; (2) it is very rapid, the patient measured need hold his breath only 0.5 second, and all the time it takes is about 2.5 minutes; (3) the measurement's sensitivity is as high as to 0.6 mm, which meets the clinic requirement entirely; (4) the measurement's accuracy of the system is not significantly when comparing to the routine ruler's. CONCLUSIONS: Computer-aided projection fringe system for measuring breast basic dimension is feasible and advanced.
