Dosimetric evaluation of GAFCHROMIC XR type T and XR type R films.

ABSTRACT: The high spatial resolution of radiochromic film makes it ideal for dosimetric measurements and dose distributions in regions of high dose gradient. Intensity-modulated radiation therapy, intravascular brachytherapy, and eye-plaque radiation therapy demand precise spatial dosimetric calculations. Such precision is not possible with conventional dosimeters, such as thermoluminescent dosimeters and ionization chambers. Recently, new GAFCHROMIC XR type T and type R films have been developed for radiation dosimetry, specifically in interventional radiology procedures. Dosimetric characteristics (i.e., linearity, post-exposure density growth, energy dependence, dose-rate dependence, and UV light sensitivity) of these new films were investigated. To evaluate the clinical applications of these fi
