但是，这种算法不能满足线X射线源圆轨道锥束扫描的情况。

However, this algorithm does not apply for circular orbit cone-beam scan with line-focus X-ray source.

着重介绍了通过对下料尺寸的改进，采用只压型线部分，锥筒部分拼接的工艺方法。

By the improvement of blanking dimension, using the technological method of only compressing profile part and conical body splice is mainly introduced.

结果：锥型线束CT可清楚显示牙根与下牙槽神经管及上颌窦之间的解剖关系。

Result: Images based on cone beam CT can clearly display the spatial relationship between root and maxillary sinus as well as inferior alveolar nerve canal.
