The distributions of radiation dose for stereotactic radiosurgery, using a modified linear accelerator (Philips SL-25 and SRS-200), have been studied by using three different dosimeters: (1) ferrous-agarose-xylenol orange (FAX) gels, (2) TLD, and (3) thick-emulsion GafChromic dye film. These dosimeters were loaded into a small volume of defect in a phantom head. A regular linac stereotactic radiosurgery treatment was then given to the phantom head for each type of dosimeter. The measured radiation dose and its distributions were found to be in good agreement with those calculated by the treatment planning computer.
利用三种不同的剂量仪，对使用改良直线加速器（飞利浦SL - 25和SRS - 200）进行立体定向放射外科手术的辐射剂量分布进行了研究：（1）亚铁 - 琼脂糖 - 二甲酚橙（FAX）凝胶，（2）热释光剂量仪，以及（3）厚乳胶GafChromic染料薄膜。将这些剂量仪置于模拟头的小体积缺损处。然后针对每种剂量仪对模拟头进行常规直线加速器立体定向放射外科治疗。发现测量所得的辐射剂量及其分布与治疗计划计算机所计算的结果高度吻合。
