A Monte Carlo computer program has been developed for the computation of integral radiation dose to the breast in xeromammography. The results are given in terms of the integral dose per unit area of the breast per unit incident exposure. The calculations have been made for monoenergetic incident photons and the results integrated over a variety of X-ray spectra from both tungsten and molybdenum targets. This range incorporates qualities used in conventional and xeromammography. The program includes the selenium plate used in xeroradiography; the energy absorbed in this detector has also been investigated. The latter calculations have been used to predict relative values of exposure and of integral dose to the breast for xeromammograms taken at various radiation qualities. The results have been applied to recent work on the reduction of patient exposure in xeromammography by the addition of aluminium filters to the X-ray beam.
已开发出一个蒙特卡罗计算机程序，用于计算干板乳腺摄影中乳房的积分辐射剂量。结果以每单位入射曝光量下乳房单位面积的积分剂量表示。已针对单能入射光子进行了计算，并对来自钨靶和钼靶的各种X射线光谱的结果进行了积分。该范围涵盖了传统乳腺摄影和干板乳腺摄影中使用的射线质。该程序包括干板X射线摄影中使用的硒板；还研究了该探测器中吸收的能量。后一种计算已用于预测在各种辐射质下拍摄的干板乳腺造影片的乳房曝光量和积分剂量的相对值。这些结果已应用于最近通过在X射线束中添加铝滤过器来减少干板乳腺摄影中患者曝光量的研究工作。
