| 中文摘要 | 计算机断层成像(CT)需要对物体进行360°扫描,由于几何限制及X射线在纵向的高吸收率,使得其在大构件尤其是板状构件的检测方面具有局限性,在这些情况下,计算机分层成像(CL)提供了一种有效的方法。本文首先总结近年来国内外关于CL的研究成果,然后系统地阐述CL成像的原理、重建算法以及应用,最后在成像质量方面比较CL和CT。; In computed tomography(CT), samples usually need to be scanned in 360 degree to obtain sufficient projection data. However, there exist difficulties for CT in inspecting large or flat samples because of geometry limitations and the high absorption close to the sample surfaces. Under these circumstances, computed laminography(CL) provides an effective alternative. Firstly, this paper summarizes researches at home and abroad recently; Secondly, principle, reconstruction algorithms and applications of CL are introduced systematically; At last, CL is compared with CT in image quality. |
