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 6MV photon beams. The results show that the FXG system can be used in profile measurements of small fields in radiotherapy.
