摘要：針對低劑量CT優(yōu)質(zhì)成像與其偽影矯正方法，開展了一系列理論性的研究，主要內(nèi)容包括基于圖像全局信息及優(yōu)化理論的低劑量CT圖像處理；關(guān)于不同掃描協(xié)議導(dǎo)引下的低劑量CT重建研究以及稀疏角度條件下的低劑量CT重建研究。

關(guān)鍵詞：低劑量CT；重建算法；偽影矯正；圖像質(zhì)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
