颈椎张口位数字摄影与常规X线摄影应用比较

The Use of Digital Radiography was Compared with Normal X-ray Radiography in Mouth-open of Cervical Vertebra

目的:比较传统屏胶系统与CR(computed radiography)、DDR(direct digital radiography)摄影技术在颈椎张口位投照中的优缺点。方法:通过投照次数、照片质量、所需时间在各种摄影方式中的差别来进行比较。结果:3种摄影方法,DDR摄影技术优势明显。结论:直接数字化摄影的发展前景更为广阔。

Objective Some of the merits and defects of normal intensifying screen-film combination were compared with CR and DDR in mouth-open of cervical vertebra. Methods To analyse differences of different radiography by shoot time and image quality and examine time. Results In the three radiography methods, DDR has distinct advantage. Conclusion The development of direct digital radiography is more widely.
