中文摘要：

提出一种基于抛物线原理的图像纠偏方法,并借助自编程序实现了偏斜颅骨CT图像的自动纠偏。该方法不仅可以用于偏斜颅骨CT图像的纠偏,也可用于其他带有抛物线特征图像的纠偏校正。

英文摘要：

The same point of each CT image should be measured in the course of geometric characteristics measuring for living human skull based on CT image, in order that the measurement results have statistic signification. So the CT image with the deviation must be rectified before the measuring. In this study the method was put forward and realized by coding into a program to rectify the image deviation based on parabola theory. This method can be used to rectify the skull CT image, and also rectify the others with parabola character.
