各种能谱CT的性能及应用差异研究
Research on the Performance and Application Differences of Various Energy Spectrum CT
摘要
Abstract
Energy spectrum CT provides richer information for imaging clinical diseases with its unique spectrum analysis tool.Based on the differences in the principles and performance of various energy spectrum CTs,this paper reviewed the radiation dose,image quality and relationship between the two of various energy spectrum CTs,as well as their differences in clinical applications such as quantitative analysis of iodine-based maps,demetalization and hardening artifacts,separation and identification of material components,display of fine structures and virtual plain scan,to provide a reference for clinical imaging workers to select energy spectrum CT according to different clinical needs,so as to maximize clinical benefits.关键词
