气管张开角的图像处理

The Trachea Opening Angle Image Processing

气管张开角是研究气管力学特性的重要指标 传统检测气管张开角的方法 ,受人为因素的干扰较多 ,结果误差大 ,而且工作繁琐 笔者利用计算机图像处理技术来对气管张开角进行检测 ,提出了一种基于极坐标的图像处理方法 ,该方法操作简单 ,人为因素降低 ,结果较为客观 。

The opening angle of trachea is an important index for studying the characteristics in trachea mechanics . Traditional methods for dete cting the trachea opening angle suffers more from the interference of anthropic factors, the error margin is bigger and the examining work is complicated and t oilsome.The writers make use of the computer image processing technology to meas ure the opening angle, and present an image processing technology based on the p olar coordinates.This technology is simple in operation,and reduces the interfer ence of the factors.And the outcome is more visual and more accurate.This method is implemented in matlab.
