A new approach to quantify the lung nodule speculation levels in CT (computed tomography) images was proposed. Firstly, two-dimensional image of nodule was generated by using the spiral scan technology. Secondly, the lung nodule was segmented in the two-dimensional image using the dynamic programming. Thirdly, based on the expanded regions from the segmented boundary, the speculation was segmented by use of threshold segmentation. Fourthly, the feature region where speculation may exist was extr

本文针对梯度折射率分布的透镜(以后简称梯析透镜)与光纤在折射率分布上的不同点,对用于光纤及其预制棒测量的聚焦法的原理公式,计算测量方法等进行了重要改进,从而使聚焦法可适用于梯折透镜的测量.本文通过计算机模拟计算,对原理公式及计算方法的准确性和可靠性进行了验证,并同时给出了这一测量方法的精度,最后给出了测量实例及其比较结果.
