A comparison of treatment planning techniques for low-dose-rate (LDR) prostate brachytherapy

Evaluation of the MIM Symphony treatment planning system for low‐dose‐rate‐ prostate brachytherapy

MIM Symphony is a recently introduced low-dose-rate prostate brachytherapy treatment planning system (TPS). We evaluated the dosimetric and planning accuracy of this new TPS compared to the universally used VariSeed TPS. For dosimetric evaluation of the MIM Symphony version 5.4 TPS, we compared dose calculations from the MIM Symphony TPS with the formalism recommended by the American Associatio...

A 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...

Low-dose-rate or high-dose-rate brachytherapy in treatment of prostate cancer – between options

PURPOSE Permanent low-dose-rate (LDR-BT) and temporary high-dose-rate (HDR-BT) brachytherapy are competitive techniques for clinically localized prostate radiotherapy. Although a randomized trial will likely never to be conducted comparing these two forms of brachytherapy, a comparative analysis proves useful in understanding some of their intrinsic differences, several of which could be exploi...

High-dose-rate Brachytherapy for Prostate

High dose rate brachytherapy for prostate cancer.

High dose rate (HDR) afterloading brachytherapy in the management of localised prostate cancer has practical, physical and biological advantages over low dose rate seed brachytherapy. There are no free live sources used, no risk of source loss and since the implant is a temporary procedure following discharge no issues with regard to radioprotection use of existing facilities. Adequate coverage...
