对ＧＥ公司ｓａｔｕｒｎｅ４２型直线加速器对准直器散射校正因子的性质进行研究，用英国ＮＥ公司生产的２６２０测量仪，臂架旋转９０°测量了６ＭＶ、１８ＭＶ的源——电离室中心距离１米及３．７米两个条件下的校正因子的数值，结果证实了校正因子只是与准直器有关与源皮距无关的结论。
The saturne42 linear accelerator of GE Company was used to study the properties of collimator scattering correction factor. The measurement was made by using the 2620 measuring instrument manufactured by NE Company of England with the boom rotated 90 ° and the center distance of 18MV source-ionization chamber being 1 meter and 3.7 meters under two conditions the value of the correction factor, the results confirm that the correction factor is only related with the collimator and the source skin is not related to the conclusion.
