Abstract:
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.
