In radiation therapy, the shielding of normal tissue can be made using Cerrobend® blocks or a multileaf collimator. In this work, profiles of shielded fields collimated by Cerrobend blocks were obtained through the Fricke Xylenol Gel (FXG) dosimeter irradiated with 6 MV photon beams. The results show that the FXG system can be used in profile measurements of small fields in radiotherapy.
在放射治疗中，可以使用铈镧合金（Cerrobend®）挡块或多叶准直器对正常组织进行屏蔽。在这项工作中，通过用6兆伏光子束照射弗里克二甲苯酚凝胶（FXG）剂量计，获得了由铈镧合金挡块准直的屏蔽野的轮廓。结果表明，FXG系统可用于放射治疗中小野的轮廓测量。
