Background and purpose: Reports using the retropubic and transperineal technique of prostate brachytherapy suggest that adequate radiation doses are required for good clinical results with I-125. After 3 years of using loose sources (LS), radioactive sources embedded in suture (SES) were introduced into our prostate brachytherapy technique. The purpose of the present report is to determine whet...

background: the formalism recommended by task group 60 (tg-60) of the american association of physicists in medicine (aapm) is applicable for β sources. radioactive biocompatible and biodegradable 153sm glass seed without encapsulation is a β- emitter with a short half life and delivers a high dose rate to the tumor in the millimeter range. in this work the dosimetry parameters of the seed for ...

OBJECTIVE To compare the efficacy and safety of high dose rate (HDR) and low dose rate (LDR) brachytherapy in treating early-stage oral cancer. DATA SOURCES A systematic search of MEDLINE, EMBASE and Cochrane Library databases, restricted to English language up to June 1, 2012, was performed to identify potentially relevant studies. STUDY SELECTION Only randomized controlled trials (RCT) an...

Recently, to eliminate problems associated with seed type sources, RadioMed Corporation (Tyngsboro, MA) introduced RadioCoil 103Pd sources for interstitial prostate implants. The RadioCoil sources are available in integral lengths ranging from 1.0 cm to 6.0 cm. In this project, dosimetric characteristics of these sources were determined following the TG-43U1 recommendations, with consideration ...

Theoretical and experimental studies have been applied for dosimetric parameters determination of the brachytherapy sources (1-3). Usually, Monte Carlo method has been used to define such quantities as the anisotropy dose function, the radial dose function, and the dose calculation close to the source in brachytherapy (4-6). Ir source is used widely in brachytherapy to treat localized tumors ne...

Brachytherapy is a medical treatment process, based on the use of radioactive sources, which are placed within the patient’s body, in order to submit a curative radiation dose to a target volume. Brachytherapy is mainly used for treating certain kinds of cancerous tumours. It can be considered as an alternative to surgery, and can be used for treating localized tumours. We dress a list of compu...

ABSTRACTBackground: Polymer gels are an emerging new class of dosimeters which are being applied to the challenges of modern radiotherapy modalities. Research on gel dosimetry involves several scientific domains, one of which is the imaging techniques with which dose data is extracted from the dosimeters. In the current work, we present our preliminary results of investigating capability of X-r...
