Determination of Dosimetric Characteristics of IrSeed 125I Brachytherapy Source
Introduction Low dose rate brachytherapy sources have been widely used for interstitial implants in tumor sites, particularly in prostate. Dosimetric characteristics of a new IrSeed 125I brachytherapy source have been determined using the LiF thermoluminescent dosimeter (TLD) chips. Materials and Methods Dose rate constant, radial dose function, and anisotropy function around the IrSeed 125I so...
متن کاملTreatment plan dosimetric impact after catheter stretch during multi-catheter interstitial breast brachytherapy
Purpose Nylon 6/6 interstitial brachytherapy catheters may stretch when exposed to moisture, mechanical tension, and body temperature. The purpose of this study is to evaluate the magnitude of catheter stretch during a course of multi-catheter interstitial breast brachytherapy for nylon 6/6 treatment catheters, and to assess the impact this has on treatment plan dosimetry. Material and method...
متن کاملDosimetric equivalence of nonstandard HDR brachytherapy catheter patterns.
PURPOSE To determine whether alternative high dose rate prostate brachytherapy catheter patterns can result in similar or improved dose distributions while providing better access and reducing trauma. MATERIALS AND METHODS Standard prostate cancer high dose rate brachytherapy uses a regular grid of parallel needle positions to guide the catheter insertion. This geometry does not easily allow ...
متن کاملDosimetric Improvements in Balloon Based Brachytherapy Using the Contura® Multi-Lumen Balloon (MLB) Catheter to Deliver Accelerated Partial Breast Irradiation
PURPOSE Preliminary dosimetric findings in patients managed with the Contura® Multi-Lumen Balloon (MLB) breast brachytherapy catheter to deliver accelerated partial breast irradiation (APBI) on a multi-institutional phase IV registry trial were reviewed. MATERIAL AND METHODS CT-based 3D planning with dose optimization was performed for all patients. For the study, new ideal dosimetric goals w...
