摘要
由于计算机技术及多层螺旋CT技术的发展,能谱CT成像从理论走向实践。能谱CT单次扫描可以获得多组单能量图像、多种基物质图像、能谱曲线、有效原子序数等,给疾病的早发现、定性、定量诊断提供了依据,本文综合文献,现综述如下。
Due to the development of computer technology and multislice computed tomography （CT） technology, spectral CT from theory to practice, spectral CT can obtain more groups of single energy in a single scan image, a variety of material, energy spectral curve, effective atomic number and so on , to the early detection of disease, provide a basis for the qualitative and quantitative diagnosis, this paper, a comprehensive literature review now as follows.
