From 6/90-2/91 the daylight system EC (Fuji Ltd.), developed only for mammography, was used in the Department of Gynaecological Radiology of the Radiological Centre of the University of Freiburg for the first time in Germany. We examined 4000 patients (respectively 14,000 mammographies). We controlled the quality of the x-ray photographs every day (n = 175) and compared the results with the controls of quality, which had been carried out from 9/89-5/90 with the conventional technique (n = 175). During the entire period of research (9/89-2/91) at both systems the results of Dmin were inferior to the standard. Using the daylight system the measurements of the index of sensitivity were in 91% of the cases (n = 160), and the index of contrast in 88% (n = 154) within the range--much better than with the conventional system with 74% (130 measurements), respectively 70% (123 measurements). We also found an evident advantage of time and in future it is to be expected that the conventional system will be replaced by the daylight system in mammography.
从1990年6月至1991年2月，仅用于乳腺摄影的日光系统EC（富士有限公司）在德国弗赖堡大学放射中心的妇科放射科首次使用。我们检查了4000名患者（共14000次乳腺摄影）。我们每天控制X线照片的质量（n = 175），并将结果与1989年9月至1990年5月使用传统技术进行的质量控制结果进行比较（n = 175）。在整个研究期间（1989年9月至1991年2月），两个系统的Dmin结果均低于标准。使用日光系统时，91%的病例（n = 160）灵敏度指数测量结果以及88%的病例（n = 154）对比度指数测量结果在该范围内——比传统系统分别为74%（130次测量）和70%（123次测量）要好得多。我们还发现了时间上的明显优势，预计未来乳腺摄影中的传统系统将被日光系统取代。
