Technical principle and clinical application of Revolution energy spectral CT / 医疗卫生装备

ABSTRACT

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.
