To estimate radiation dose during mammography the breast thickness must be known. We present a new method for estimating the thickness of a compressed breast using only the breast image as projected onto a mammogram, calibration data such as the mAs value and image processing techniques. The method proves to be of high accuracy (+/- 0.2 cm for craniocaudal mammograms) and has the advantage over other methods of allowing retrospective estimation of thickness.
为了估算乳腺钼靶摄影期间的辐射剂量，必须知道乳房厚度。我们提出了一种新方法，仅利用乳房投影在乳腺钼靶片上的图像、校准数据（如毫安秒值）以及图像处理技术来估算压缩乳房的厚度。该方法被证明具有很高的准确性（头尾位乳腺钼靶片的误差为±0.2厘米），并且与其他方法相比具有能够对厚度进行回顾性估算的优势。
