Revolution能谱CT技术原理与临床应用

Technical principle and clinical application of Revolution energy spectral CT

从探测器、驱动系统及CT球管和高压发生器3个方面介绍了Revolution能谱CT在结构上的创新,从冠状动脉运动追踪冻结成像、多模型迭代重建算法、无限制心脏成像、物质分离与定量分析4个方面分析了Revolution能谱CT的技术原理,阐述了Revolution能谱CT在肝癌、胆囊结石、肾脏结石诊断,冠状动脉造影,去金属伪影方面的临床应用。指出了Revolution能谱CT将是鉴别病灶的性质、肿瘤是否同源性,无机物成分鉴别,多物质定量定性分析的一种新方法,能更好地应对CT在临床应用中的技术性挑战。

Revolution energy spectral CT had its structural innovation introduced from the aspects of detector,driving system and CT bulb as well as high voltage generator,technical principle analyzed from the aspects of SSF,multi-model iterative reconstruction,cardiac imaging unlimited as well as material separation and quantitative analysis,and clinical application described in diagnoses of liver cancer,cholecystolithiasis and kidney stone,coronary arteriongraphy and metal artifact elimination.It's pointed out Revolution energy spectral CT was a new method for identifying the focal nature,tumor homology and components of inorganic substance as well as analyzing multi material quantitatively and qualitatively.
