Negative-mode xeroradiography is discussed in relation to the clinical indications and the radiation doses in the breast per exposure. The radiation doses have been obtained using a computer algorithm specially designed to calculate breast volumes by constructing a three-dimensional body from the two dimensional cranio-caudal and medio-lateral images. A mathematical integration procedure is then applied throughout the volume to obtain the absorbed dose.
讨论了乳腺干板X线摄影术的阴性模式与临床适应症以及每次照射时乳腺所受辐射剂量的关系。辐射剂量是通过一种专门设计的计算机算法获得的，该算法通过从二维的头尾位和内外侧位图像构建三维身体来计算乳腺体积。然后在整个体积上应用数学积分程序以获得吸收剂量。
