Dosimetric characterization of round HDR 192Ir accuboost applicators for breast brachytherapy.
PURPOSE The AccuBoost brachytherapy system applies HDR 192Ir beams peripherally to the breast using collimating applicators. The purpose of this study was to benchmark Monte Carlo simulations of the HDR 192Ir source, to dosimetrically characterize the round applicators using established Monte Carlo simulation and radiation measurement techniques and to gather data for clinical use. METHODS Do...
متن کاملMonte Carlo investigation on precise dosimetry of HDR breast brachytherapy with Accuboost
Introduction: Accuboost is a HDR brachytherapy system in early stages breast cancer treatment. This device provides a completely noninvasive procedure with parallel-opposed radiation from two immobilizing peripheral applicators that caused it a preferred option of modalities to choose. In most commercial treatment planning systems, tissues are considered as a simple water phan...
متن کاملDosimetric characterization and output verification for conical brachytherapy surface applicators. Part I. Electronic brachytherapy source.
PURPOSE Historically, treatment of malignant surface lesions has been achieved with linear accelerator based electron beams or superficial x-ray beams. Recent developments in the field of brachytherapy now allow for the treatment of surface lesions with specialized conical applicators placed directly on the lesion. Applicators are available for use with high dose rate (HDR)(192)Ir sources, as w...
متن کاملEvaluation of BEBIG HDR 60Co system for non-invasive image-guided breast brachytherapy
PURPOSE HDR (60)Co system has recently been developed and utilized for brachytherapy in many countries outside of the U.S. as an alternative to (192)Ir. In addition, the AccuBoost(®) technique has been demonstrated to be a successful non-invasive image-guided breast brachytherapy treatment option. The goal of this project is to evaluate the possibility of utilizing the BEBIG HDR (60)Co system f...
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 ...
