UNLABELLED
Comparison of image quality between conventional film screen system, digital phosphor storage plate mammography in magnification technique and digital mammography in CCD-technique.
MATERIALS AND METHODS
Radiograms of a RMI-mammography phantom were acquired using a conventional film screen system, two digital storage plate systems and two digital systems in CCD-technique. Additionally, the radiograms of one digital phosphor storage plate system were postprocessed emphasizing contrast and included in the comparison.
RESULTS
The detectability of details was the best with the digital mammography in CCD-technique in comparison with the conventional film screen technique resp. digital phosphor storage plate in magnification technique.
CONCLUSIONS
Based on these results there is the possibility to replace the conventional film screen system by further studies--this has to be confirmed.
未标注
传统胶片屏系统、数字磷光存储板乳腺X线摄影放大技术与电荷耦合器件（CCD）技术数字乳腺X线摄影的图像质量比较。
材料与方法
使用传统胶片屏系统、两个数字存储板系统和两个CCD技术数字系统获取RMI乳腺摄影体模的X线片。此外，对一个数字磷光存储板系统的X线片进行强调对比度的后处理并纳入比较。
结果
与传统胶片屏技术及数字磷光存储板放大技术相比，CCD技术数字乳腺X线摄影对细节的可检测性最佳。
结论
基于这些结果，有可能通过进一步研究取代传统胶片屏系统——这有待证实。
