The authors compared the radiation dose to the patient and the image quality in advanced multiple-beam equalization radiography (AMBER) with those in conventional chest radiography. Organ doses were estimated for an anthropomorphic phantom from measurements with thermoluminescence dosimeters. These measurements were supplemented with area-air kerma products obtained during chest examinations of 223 patients. Image quality was determined by means of a contrast-detail image evaluation test. An improvement in image quality in regions of high absorption and an increased dose to the patient were found for the AMBER technique compared with the conventional technique. However, for both techniques, the radiation exposure was relatively low compared with other reported values of patient dose during chest radiography. The estimated effective dose for an average-size patient during chest radiography with posteroanterior and lateral projections is 0.085 mSv for the conventional and 0.14 mSv for the AMBER technique.
作者比较了先进多束均衡射线照相术（AMBER）与传统胸部射线照相术中患者所接受的辐射剂量及图像质量。使用热释光剂量计对一个人体模型进行测量，估算器官剂量。这些测量结果辅以在223例患者胸部检查期间获得的面积-空气比释动能乘积。通过对比细节图像评估测试来确定图像质量。与传统技术相比，AMBER技术在高吸收区域的图像质量有所改善，但患者所接受的剂量增加。然而，与其他报道的胸部射线照相术中患者剂量值相比，这两种技术的辐射暴露都相对较低。对于平均体型的患者，在进行前后位和侧位投影的胸部射线照相时，传统技术的估计有效剂量为0.085 mSv，AMBER技术为0.14 mSv。
