Fricke dosimeter gel measurements of the profiles of shielded fields.
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.
