摘要： 目的 研制肺压缩程度计算软件，以期在法医临床鉴定工作中对于气胸患者的肺压缩比值进行准确、快速的计算，进而客观地进行损伤程度评定。 方法 根据CT机的工作原理制作体积计算软件。采集15例气胸患者的CT影像学资料作为研究对象，应用CT机附带的体积计算软件计算气胸患者的肺压缩比值，同时，利用研制的肺压缩体积计算软件计算肺压缩比值。对两种方法计算所得肺压缩比值及操作时间进行统计学分析，并据相关数据绘制散点图，对研制的体积计算软件进行验证。 结果 两种方法所得肺压缩比值差异均无统计学意义，且呈线性相关（P<0.05），研制的体积计算软件运算时间明显较短。 结论 本研究所研制的体积计算软件可准确计算气胸肺压缩程度，且更为方便快捷、易于操作，在法医学实践中有应用价值。

Abstract: Objective To develop a measurement software of lung compression degree to calculate the lung compression ratio in pneumothorax patients accurately and quickly, and then provide an objective assessment of damage degree in forensic clinical identification. Methods A volume calculation software was established according to the working principle of the CT instrument. CT data of 15 pneumothorax patients were selected as research objects. The lung compression ratio of pneumothorax patient was calculated by the lung compression volume calculation software of the CT instrument. Meanwhile, the lung compression ratio was also calculated by the developed volume calculation software. The lung compression ratio and operation time calculated by the two methods were analyzed statistically. Scatter plot graphs were draw based on related data, and the developed volume calculation software was verified. Results The difference between the lung compression ratios calculated by the two methods was not statistically significant, but showed a linear correlation （P<0.05）. The operation time of the developed volume calculation software was obviously shorter. Conclusion The volume calculation software developed in this study can calculate the lung compression degree of pneumothorax more conveniently and rapidly with easy accessibility, which shows an application value in the forensic practice.
