This study focuses on the use of MgBO:Dy,Na dosimeters in mammography measurements. The reproducibility measurement and dose-response curves were studied for the characterization of dosimeters. Next, variation in entrance surface dose (ESD) and mean glandular dose (MGD) was investigated according to different glandularity/adipose tissue ratios of 30%/70%, 50%/50% and 70%/30% for fixed anode and variable filter combinations (Mo/Mo, Mo/Rh) using BR-12 phantoms with thicknesses from 2 to 6 cm. The ESD and MGD values increased at varying rates with increasing phantom thicknesses and glandularity ratios. The increase rate in MGD is ∼30% for both Mo/Mo and Mo/Rh for the difference between (70%/30%) and (50%/50%), considering the thickness of 6 cm. On the other hand, the MGD value obtained for a glandular ratio of 70%/30% at 6 cm for Mo/Mo is ∼40% higher than that for Mo/Rh. A proportional comparison of MGD differences obtained according to glandularity and filter changes may provide valuable contributions to the literature. Within this study, it was shown that MgBO:Dy,Na dosimeters can be used as new alternative dosimeters in the field of mammography to perform ESD and MGD measurements. In further studies, MgBO:Dy,Na dosimeters can be used to determine the various organ doses, such as eye and thyroid, resulting from the scattered radiation dose using rando phantoms.

在乳房 X 光检查中使用 MgB4O7:Dy,Na 剂量计评估具有不同腺体/脂肪组织比例的体模的平均腺体剂量 (MGD)

本研究重点关注 MgBO:Dy,Na 剂量计在乳房 X 线摄影测量中的使用。研究了再现性测量和剂量响应曲线，以表征剂量计。接下来，根据固定阳极和可变阳极的不同腺体/脂肪组织比率 30%/70%、50%/50% 和 70%/30%，研究入口表面剂量 (ESD) 和平均腺体剂量 (MGD) 的变化使用厚度为 2 至 6 厘米的 BR-12 模型的滤光片组合（Mo/Mo、Mo/Rh）。随着体模厚度和腺体比率的增加，ESD 和 MGD 值以不同的速率增加。考虑到 6 cm 的厚度，对于 (70%/30%) 和 (50%/50%) 之间的差异，Mo/Mo 和 Mo/Rh 的 MGD 增加率约为 30%。另一方面，Mo/Mo 在 6 cm 处腺体比例为 70%/30% 时获得的 MGD 值比 Mo/Rh 高约 40%。根据腺体和过滤器变化获得的 MGD 差异的比例比较可能为文献提供有价值的贡献。本研究表明，MgBO:Dy,Na 剂量计可用作乳房 X 线摄影领域的新替代剂量计，以执行 ESD 和 MGD 测量。在进一步的研究中，MgBO:Dy,Na 剂量计可用于确定各种器官的剂量，例如眼睛和甲状腺，这是由使用随机体模的散射辐射剂量产生的。
