Researches for the Pules X-Ray Fluoroscopy Technology Based on CCD Imaging
【摘要】 从考察1.1-TVsX射线成像系统常见的工作模式和CCD视频成像的基本原理出发,分析成像系统中高频逆变电源、X射 线发生器、影像增强器等主要设备单元的协同工作过程,提出一种新型的CCD视频图像采集脉冲X射线成像技术方法 并介绍了此方法在具体实现中所面临的问题和应对措施。
【Abstract】 In this paper, a novel method is proposed to be used for the pulse X-ray fluoroscopy based on CCD video imaging. The synchronization relationship between CCD image capturing and pulse X-ray generating is analyzed, and some technology questions about CCD, image intensifier, high frequency inverter, and X-ray generator are discussed and settled.
