System Improvement by Replacing Light-Conductor Camera with CCD Camera

目的:通过采用CCD摄像机取代老化的光导管摄像机,使影像增强电视系统继续发挥作用。方法:选择低照度高灵敏度的CCD摄像机,配制X射线剂量自动控制器。结果:经过改进后的CCD配套影像增强电视系统能够达到临床使用的要求。结论:用CCD摄像头取代已老化的光导管摄像机,能够达到临床使用要求。明确了将通用CCD摄像机配套为影像增强电视系统的可行性。

Objective To improve the image intensifying X-TV system by replacing the light-conduct camera with CCD camera for future usage. Mthods The low luminous and high sensitive CCD camera was used in the X-ray auto exposure dose control. Results Through the practical improvement, the CCD X-TV system met the clinical requirements. Conclusion It is an effective way to replace the old light-conduct camera with CCD camera, and it also helpful for the alternative solutions for X-TV.
