电子束CT特性及临床应用研究

Research on characteristics and clinical applications of EBCT

目的:充分掌握EBCT的各种特性及其临床应用的优势。方法:通过使用不同的扫描模式进行比较分析和研究。结果:电子束CT使用电子束的磁偏转代替球管机械运动,既加快扫描速度,又减少机械磨损,有很高的时间分辨率。结论:EBCT尤其适合于心血管、运动脏器、不合作病人的检查及CT透视等方面的应用。

Objective To master the various characteristics of EBCT and it＇s applications in clinic in depth. Methods Different scan modes were compared with each other. Results EBCT had the advantage of high speed in scanning and high resolving power of time without mechanical abrasion due to the using of electron beam. Conclusion EBCT is suitable for the examinations of cardiovascular system, and moving organs and uncooperative patients, and also for the application to CT fluoroscopy.
