扩张皮肤三维图像及面积、体积测量软件的开发和应用

目的 介绍用于测量扩张皮肤面积和体积，并形成三维图像的专用软件。方法 通过输入扩张皮肤的基底面、正中横截面和纵截面作为基本参数，扩张皮肤表面的其它部位三维坐标经过图形平滑过渡（插值计算）获得。软件是用Ｃ语言编制，运行在Ｗｉｎｄｏｗｓ下。结果据此测量面积和体积并形成三维图像。经初步验证其最大误差小于４％。结论 结合以往的三维表面转换成平面测量扩张面积的方法，该软件为测量扩张皮肤提供了一种可行的方法

A special software for area and volume measurement and 3D image of skin expander

Objective A special software for measuring expanded skin area and volume and creating a 3D image of skin expander protrusion has been introduced.Methods The 3D coordinates of all the points on the surface were obtained by means of interpolation in computer,according to its base,central horizontal and vertical sections that should be adopted in advance. This software was programmed with C language and performed in Microsoft Windows. Results The area,volume,and 3D image were acquired according to 3D coordinates.The deviation of the software measurement was less than 4% of actual sizes at most in our reliability demonstration. Conclusion This software,combined with our protocol of conversion from tridimensional surface to a plane reported previously,makes up a preferable scheme in this field.
