摘要：针对低剂量CT优质成像与其伪影矫正方法，开展了一系列理论性的研究，主要内容包括基于图像全局信息及优化理论的低剂量CT图像处理；关于不同扫描协议导引下的低剂量CT重建研究以及稀疏角度条件下的低剂量CT重建研究。
关键词：低剂量CT；重建算法；伪影矫正；图像质量
Abstract：The year 2010 is the first year of this research. Theoretical research on the topic “High Quality Low Dose CT （LDCT） Imaging And Artifact Correction” has been carried on during this year. The contents of the research includes low dose CT image processing based on global image information and optimization framework； low dose CT reconstruction guided by different scanning protocol； and low dose CT reconstruction under sparse view scan mode. The achievements we made provide us with a good foundation for the following research.
Keywords：Low dose CT（LDCT）， reconstruction algorithm， artifact correction， image quality
