Measurements of compressed breast thickness during mammography is necessary for the calculation of breast dose. In theory, it should be possible to calculate breast thickness from the separation of images of radio-opaque markers attached to the compression paddle. Such a technique has been evaluated on two models of X-ray set using simulated and real breasts. The results show that breast thickness at a given position can be determined with an average error of about 2 mm by this method, which is likely to be adequate for dosimetry.
在乳房X线摄影期间测量压缩乳房厚度对于计算乳房剂量是必要的。理论上，应该可以根据附着在压迫板上的不透射线标记物的图像间距来计算乳房厚度。已经在两种型号的X射线设备上使用模拟乳房和真实乳房对这种技术进行了评估。结果表明，用这种方法可以确定给定位置的乳房厚度，平均误差约为2毫米，这对于剂量测定可能是足够的。
