The accuracy and precision are necessary factors in radiotherapy, especially for measurements involving output factors and beam profiles; in this case multileaf collimators (MLCs) and dosimeter systems are not employed to obtain an adequate absorbed dose. In this work, output factors and beam profiles using multileaf collimators were obtained through the Fricke Xylenol Gel (FXG) dosimeter irradiated with 6 MV photon beams. From the results, FXG dosimetry demonstrated to be an adequate dosimetric tool for radiotherapy applications using MLC.
准确性和精确性是放射治疗中的必要因素，尤其是对于涉及输出因子和射野剂量分布的测量；在这种情况下，不使用多叶准直器（MLC）和剂量计系统来获得足够的吸收剂量。在这项工作中，使用6兆伏光子束照射弗里克二甲苯酚凝胶（FXG）剂量计，获得了使用多叶准直器的输出因子和射野剂量分布。从结果来看，FXG剂量测定法被证明是一种适用于使用MLC的放射治疗应用的剂量测定工具。
