ABSTRACT:
In this
study, we fabricated a Cerenkov fiber-optic dosimeter (CFOD) without any
scintillator to measure Cerenkov radiation signals owing to gamma-rays. The relative
depth dose (RDD) distributions of Ir-192 HDR brachytherapy source were obtained
by using the CFOD based on a subtraction method and the RDD curve was compared
with the simulation result of Monte Carlo N-particle extended transport code
(MCNPX). Finally, we demonstrated that the CFOD can be used to measure
real-time dose information for HDR brachytherapy.
