摘要
本文研究了不同厚度轻重物质在射线透射成像中的图像灰度关系,根据提取轻物质轮廓线的要求,找出了在不同厚度重物质遮挡下的可检测出轻物质的最小厚度曲线。
The paper probes into the gray relation of the transmission CT image of the substance of various thickness. We find out the curve of minimal thickness that can exam the light substance covered by the heavy substance of various thickness in accordance with the request of picking out the profile.
