PURPOSE We performed a survey amongst attendees of the 4(th) Annual Meeting of Indian Brachytherapy Society to study the patterns of brachytherapy practice and attitude towards brachytherapy use. MATERIAL AND METHODS A 19-point questionnaire was designed and e-mailed to the attendees immediately after the conference. Descriptive analysis of the responses were done and satisfaction index was u...

The biological rationale for the use of brachytherapy, which is undergoing a significant resurgence in the United States, is reviewed with emphasis on low dose rate (LDR brachytherapy). Some of the newer alternatives that have recently been developed, such as pulsed dose rate (PDR) brachytherapy, are discussed.

Purpose: Dosimetric analysis and effect of different definitions prescription point “A” to OAR in high dose rate brachytherapy for cervical cancer. Methods Materials: This retrospective comparative dosimetric study is based on the data 25 patients with histologically proven carcinoma treated HDR (high-dose-rate) brachytherapy. Patients received 21 Gy three fractions (7.0 X fractions) A (AMAN, r...

Background: Iodine brachytherapy sources with low photon energies have been widely used in treating cancerous tumors. Dosimetric parameters of brachytherapy sources should be determined according to AAPM TG-43U1 recommendations before clinical use. Monte Carlo codes are reliable tools in calculation of these parameters for brachytherapy sources. Materials and Methods: Dosimetric param...

Cobalt-60 (Co-60) is a relatively new source for the application of high-dose rate (HDR) brachytherapy. Radiation dose to the rectum is often a limiting factor in achieving the full prescribed dose to the target during brachytherapy of cervical cancer. The aim of this study was to measure radiation doses to the rectum in-vivo during HDR Co-60 brachytherapy. A total of eleven HDR brachytherapy t...

introduction: polymer gels are modern dosimeters providing three dimensional dose distributions. these dosimeters can be used in brachytherapy in which the tumor dimension is relatively small and the dose gradient is high. in this study, the ability of the magica polymer gel was investigated for assessing the absolute dose values as well as the dose distribution of low dose rate (ldr) ir-192 wi...

background: the purpose of this project was to derive the brachytherapy dosimetric functions described by american association of physicists in medicine (aapm) tg-43 u1 based on high dose rate 192i sources. materials and methods: the method utilized included both simulation of the designed polymethyl methacrylate (pmma) phantom using the monte carlo of mcnp4c and benchmarking of the simulation ...
