目的 构建超声心动图左室舒张功能计算机辅助诊断系统,旨在使左室舒张功能评价过程更加方便快捷、合理规范,评判结果更加准确、可靠.方法 应用Macromedia Flash Professional为开发工具,以美国超声心动图学会（ASE）2009年颁布的诊断指南为规范蓝本,构建超声心动图左室舒张功能辅助评价系统软件,通过临床测试和应用对系统进行修正和完善.结果 辅助评价系统与超声心动图检查同步进行,将ASE指南建议测定的评价参数值输入系统,系统快捷地对左室充盈压和左室舒张功能的变化情况作出自动判断和分级,并以图文一体化以及规范化报告直观显示评判结果.结论 超声心动图辅助评价系统规范和简化了左室舒张功能的评价过程,有效保证了评判结果的客观性和可靠性,具有较高的临床推广价值.

英文摘要：

Objective To build the computer-aided diagnosis system of left ventricular diastolic function for echocardiography,to make the evaluation process of left ventricular diastolic function for echocardiography more convenient,efficient,standardized and to obtain more accurate,practical,objective and reliable diagnostic results.Methods First,the system was developed by the Macromedia Flash Professional referred to the newest guidelines and suggestions published by the American Society of Echocardiography（ASE） in 2009.Second,the program of left ventricular diastolic function in the computer- aided diagnosis system was designed,debugged and improved according to feedback information from practical applications.Results The diagnostic system can work simultaneously with echocardiography.If assessment parameters of the newest guidelines and suggestions,published by the American Society of Echocardiography in 2009,are imported to the system,then it can give the diagnosis of the change about the left ventricle filling pressures and score the left ventricular diastolic function quickly and automatically.The system will export standard report with both pictures and text.Conclusions According to our experiment,the computer-aided diagnosis system is able to make the evaluation process of left ventricular diastolic function much more standardized and simplified,which guarantee the objectivity and reliability of the evaluation results.Consequently,it will be able to apply to clinical practice in the future.
