GAFChromic膜MD-55-2最近被广泛应用于工业、科学和医疗辐射剂量计。我们将这些胶片应用于Leksell伽玛刀治疗的剂量测定。我们使用平板图像扫描仪拍摄照射的MD-55-2的数字图像，并将数据转换为红色、绿色和蓝色像素值。从红色像素值的响应曲线得出的吸收剂量与Leksell伽马计划剂量计划系统一致，用于使用准直器尺寸4 mm、8 mm和14 mm的曝光。然而，由于头部体模中复合材料的密度效应，18 mm准直器曝光中的最大剂量测得比伽马计划小约5%。
GAFChromic films MD-55-2 have recently been established widely in industrial, scientific, and medical applications as radiation dosimeters. We applied these films to the dosimetry for Leksell Gamma Knife therapy. We used a flatbed image scanner to take digital images of irradiated MD-55-2, and the data were converted to Red, Green and Blue pixel values. The absorbed dose, as derived from the response curve of the Red pixel value, was consistent with the Leksell Gamma Plan dose planning system, for exposures using collimator sizes, 4 mm, 8 mm, and 14 mm. However, the maximum dose in the exposure of the 18 mm collimator was measured to be about 5% smaller than Gamma Plan due to the density effect of the compound material in the head phantom.
