摘　　要：研发一种简便可靠的测算晶状体曲率和体积参数的计算机图像处理软件。以晶状体B超图像为基础,根据几何原理,设计测算晶状体前、后表面曲率半径和体积的软件。该软件包括方案一和方案二,其测算方法不同。将两个方案分别应用于同一组随机抽样的正常人,并对测算结果进行比较。结果表明两个软件方案均成功开发,测算的晶状体前、后表面曲率半径和体积的结果均值接近,方案二较方案一标准差数值小。该软件设计科学,操作简便。初步应用的结果表明,方案二较方案一计算重复性好,具有临床研究和应用前景。This project was aimed to develop a simple,convenient and reliable computer image processing software for the measurement of lens dimensions,including the radius of curvature of anterior lens surface（RCALS）,the radius of curvature of posterior lens surface（RCPLS） and the lens volume（LV）. On the basis of lens images captured by B ultrasound,our computer software was designed to calculate the three parameters of lens in accordance to geometry principle.This software comprises Program Ⅰ and Program Ⅱ,and they both possess different calculation methods.Then they were used in a group of normal volunteers who were recruited via randomization and the outcomes were compared.The results showed that the two programs were developed successfully,and the outcomes of RCALS,RCPLS and LV calculated by the two programs were similar.The standard deviation of Program Ⅱ is smaller than that of Program Ⅰ.The computer software for calculating RCALS,RCPLS and LV was characterized by scientific design and easy-to-use.In respect of calculating repetition,Program Ⅱ was better than Program Ⅰ,and it possesses prosperous prospect in terms of clinical research and application.
