Full field digital mammography (FFDM) has advantages over screen-film mammography (SFM), but some important challenges remain. The first challenge is related to the specific characteristics of FFDM. It remains unclear, which shape and limiting values of the modulation transfer function have the most influence on the performance of a detector, such as the effect of the image display on the overall image quality and the effect of processing on cancer detection. In order to assess the image quality of FFDM, we have set up a scoring system. The second challenge is related to screening mammography: is the quality of an image the same when it is viewed on different monitors and with different processing algorithms? Is Computer Aided Diagnosis necessary in a screening environment? In FFDM, the effect of different detectors, processing and display possibilities on the image and on cancer detection are not clearly investigated.
全视野数字乳腺摄影(FFDM)相较于屏-片乳腺摄影(SFM)具有优势,但仍存在一些重要挑战。第一个挑战与FFDM的特定特性有关。目前尚不清楚调制传递函数的哪种形状和极限值对探测器性能影响最大,例如图像显示对整体图像质量的影响以及处理对癌症检测的影响。为了评估FFDM的图像质量,我们建立了一个评分系统。第二个挑战与乳腺筛查有关:当在不同显示器上以不同处理算法查看图像时,图像质量是否相同?在筛查环境中计算机辅助诊断是否必要?在FFDM中,不同探测器、处理和显示可能性对图像及癌症检测的影响尚未得到明确研究。
