摘要
本文综述了多层螺旋CT的近期研究进展。对CT扫描结构、锥形束重建算法、螺旋CT重建算法、检测器排列等方面进行了评述,对各种方法的扫描时间、扫描覆盖范围、空间分辨率进行了比较和评价,并展望了多层螺旋CT今后的发展方向。
A review of recent development in multislice spiral CT is given. The principles and progress of CT scanning structure, cone-beam reconstruction, spiral CT reconstruction and detector-array arrangement, are described. This paper presents comparisons of various reconstruction methods in terms of scanning time, scanning coverage and space resolution. The future development of multislice spiral CT is also discussed.
