Treatment plan optimization for rotating-shield brachytherapy
In this thesis, we aim to develop fundamentally new techniques and algorithms for efficiently computing rotating-shield brachytherapy (RSBT) treatment plans. We propose that these algorithms will pave the way for making RSBT available in clinical practices. RSBT is an intensity modulated high-dose-rate brachytherapy (HDR-BT) technique. Theoretically, RSBT offers advantages over the conventional...

متن کاملInterstitial rotating shield brachytherapy for prostate cancer.
PURPOSE To present a novel needle, catheter, and radiation source system for interstitial rotating shield brachytherapy (I-RSBT) of the prostate. I-RSBT is a promising technique for reducing urethra, rectum, and bladder dose relative to conventional interstitial high-dose-rate brachytherapy (HDR-BT). METHODS A wire-mounted 62 GBq(153)Gd source is proposed with an encapsulated diameter of 0.59...
متن کاملA novel perineal shield for low-dose-rate prostate brachytherapy
PURPOSE To study the impact on radiation exposure to staff through the use of an original perineal shield during low-dose-rate prostate brachytherapy. MATERIAL AND METHODS We designed a 1 mm thick stainless steel shield that duplicates and is able to slide directly over a standard commercialized prostate brachytherapy grid. We then analyzed the post-procedure exposure in 15 consecutive patien...
متن کاملGlobal convergence analysis of fast multiobjective gradient-based dose optimization algorithms for high-dose-rate brachytherapy.
We consider the problem of the global convergence of gradient-based optimization algorithms for interstitial high-dose-rate (HDR) brachytherapy dose optimization using variance-based objectives. Possible local minima could lead to only sub-optimal solutions. We perform a configuration space analysis using a representative set of the entire non-dominated solution space. A set of three prostate i...
