A breast phantom of novel design has been used to measure visibility of simulated calcific and soft-tissue fibrillar details in mammography, as well as to determine the roentgen exposure vs. depth. Exposure data were combined with a model of the breast as compressed during mammography to compute the mean exposure to the ductal parenchyma (MDE). Three different imaging systems were compared over a wide range of x-ray beam energies and breast characteristics. "Dosage" criteria other than the MDE are discussed.
一种新型设计的乳房模型已被用于测量乳腺摄影中模拟钙化和软组织纤维细节的可见性,以及确定伦琴曝光量与深度的关系。曝光数据与乳房在乳腺摄影过程中被压缩的模型相结合,以计算导管实质的平均曝光量(MDE)。在广泛的X射线束能量和乳房特征范围内,对三种不同的成像系统进行了比较。还讨论了除MDE之外的“剂量”标准。
