Determination of bladder and rectal dose using MOSFET and radiochromic film: a phantom study

Dosimetry measurements are important for quality assurance in Brachytherapy sources with energy more than 100 KeV. Even 1.25 MeV sources were used, hence the major challenge in Brachytherapy is to verify the accuracy of dose distributions calculated by the treatment planning system. In vivo study of bladder and rectal dose in HDR is a tedious process and the patient safety is of higher concern. In this regard, measuring the bladder and the rectal dose is of prime concern with respect to intracavitary Brachytherapy
