美国国家癌症研究所（NCI）电子束治疗计划合同的合作工作组（CWG）进行了一组14个实验，测量了28个独特的束体模配置，模拟各种患者的解剖结构和束几何形状的剂量分布。多个剂量分布进行了测量，薄膜或二极管探测器为每个配置，导致78，2-D平面剂量分布和一个，1-D深度剂量分布。测量了9-和20-MeV的电子束，主要使用6 X 6-和15 X 15-cm的喷头在几个SSD。剂量分布进行了测量的形状字段，不规则的表面，和不均匀性（1-D，2-D和3-D），这是为了模拟许多临床电子治疗。对数据进行不对称校正，并以绝对方式进行归一化。这组测量数据可用于验证电子束剂量算法，并可供其他人用于该目的。
The Collaborative Working Group (CWG) of the National Cancer Institute (NCI) electron beam treatment planning contract has performed a set of 14 experiments that measured dose distributions for 28 unique beam-phantom configurations that simulated various patient anatomic structures and beam geometries. Multiple dose distributions were measured with film or diode detectors for each configuration, resulting in 78, 2-D planar dose distributions and one, 1-D depth-dose distribution. Measurements were made for 9- and 20-MeV electron beams, using primarily 6 X 6- and 15 X 15-cm applicators at several SSDs. Dose distributions were measured for shaped fields, irregular surfaces, and inhomogeneities (1-D, 2-D, and 3-D), which were designed to simulate many clinical electron treatments. The data were corrected for asymmetries, and normalized in an absolute manner. This set of measured data can be used for verification of electron beam dose algorithms and is available to others for that purpose.
