The proposed algorithm is based on the symmetry projection information implied in the sinogram and the following law: in relation to the two symmetrical projection views,the transmission path of the X-ray which passes through the COR of the rotating table is the same.
本文在详细分析了现存旋转中心确定方法不足的基础上,提出了一种新方法,该方法利用隐含在正弦图中的对称投影信息,并根据经过旋转中心的射线束在两个对称投影视角下透过的物体路径相同这一规律来定位旋转中心。
