A Simple Function Describing the Absorption in Platinum for Dose-Rate Calculations Around Radium Applicators

A broadly applicable function for describing luminescence dose response

A method for checking high dose rate treatment times for vaginal applicators

A method is presented for checking the treatment time calculation for high dose rate (HDR) vaginal cylinder treatments. The method represents an independent check of the HDR planning system and can take into account nonuniform isodose line coverage around the cylinder. Only the air kerma strength of the source and information that is available from the written directive are required. The maximu...

Positional variation of applicators during low dose rate intracavitary brachytherapy for cervical cancer: a prospective study

PURPOSE In order to know the effect of variation in position of applicators to the dose received by the tumor volume, critical organs such as rectum and bladder and the correlation of variation on the clinical outcome. MATERIAL AND METHODS 36 patients with histologically proven cervical cancer, undergoing intracavitary brachytherapy (ICBT) from October 2005 to December 2006 were the subjects ...

Applicator Attenuation Effect on Dose Calculations of Esophageal High-Dose Rate Brachytherapy Using EDR2 Film

Introduction Interaluminal brachytherapy is one of the important methods of esophageal cancer treatment. The effect of applicator attenuation is not considered in dose calculation method released by AAPM-TG43. In this study, the effect of High-Dose Rate (HDR) brachytherapy esophageal applicator on dose distribution was surveyed in HDR brachytherapy. Materials and Methods A cylindrical PMMA phan...

Gamma Dose Rate Measurement and Dose Rate Calculation for Sensitive Organs in the Vicinity of Hot Springs in Kerman Province

Introduction:  All of  the  people worldwide  are exposed  to  low levels  of  radiation. Cancer induction  and  genetic disorders are among the hazards of low level exposure. In some cases, radiation close to hot springs is  higher than normal areas due to a high concentration and the decay products of Ra-226. Given the use of hot  springs by the general public  because  of their therapeutic p...
