Prostate Brachytherapy: High Dose Rate
2012Prostate cancer is the most common male malignancy in the Western world. Over the past decade, a significant shift has taken place in stage at diagnosis, with most patients now presenting with localized disease. Options for treatment include radical prostatectomy and different radiation modalities including external beam radiotherapy, low-dose-rate ...

Image‐guided high dose rate endorectal brachytherapy
Medical Physics, 2007Fractionated high dose rate endorectal brachytherapy (HDR‐EBT) using CT‐based treatment planning is an alternative method for preoperative down‐sizing and down‐staging of advanced rectal adeno‐carcinomas. The authors present an image guidance procedure that was developed to ensure daily dose reproducibility for the four brachytherapy treatment ...

Optimization of planar high-dose-rate implants
International Journal of Radiation Oncology*Biology*Physics, 1999Brachytherapy has long been used to deliver localized radiation to the breast and other cancer sites. For interstitial implants, proper source positioning is critical in obtaining satisfactory dose distributions. The present work examines techniques for optimizing source guide placement in high-dose-rate (HDR) biplanar implants, and examines the ...

Endobronchial high dose rate brachytherapy
International Journal of Radiation Oncology*Biology*Physics, 1993Endobronchial brachytherapy for malignant airway obstructions has been used at several institutions using various radionuclides for decades. As small, high-activity, Iridium- 192 sources and remote afterloading systems became available, high dose rate (HDR) endobronchial irradiation became popular.

Afterloading high dose rate intracavitary vaginal cylinder
International Journal of Radiation Oncology*Biology*Physics, 1994To design an afterloading vaginal cylinder application appropriate to treat the vault with high dose rate (HDR) brachytherapy after prior total abdominal hysterectomy.A vaginal cylinder was designed and built using nylon and source loading channels positioned for source movement for HDR vault and vaginal brachytherapy.

IEEE Transactions on Nuclear Science, 2019
Based on gated lateral p-n-p (GLp-n-p) transistors, the correlation between the high dose rate (HDR) and low dose rate (LDR) irradiations during the switched dose rate experiments is investigated. Experimental results show that a significant deviation of the current gain degradation caused by switching dose rate irradiations from that by individual LDR

Partial breast brachytherapy after lumpectomy: Low-dose-rate and high-dose-rate experience
International Journal of Radiation Oncology*Biology*Physics, 2003The use of partial breast brachytherapy (PBB) after lumpectomy for selected patients with early-stage breast cancer reduces the adjuvant radiotherapy treatment time to

Dose rate in brachytherapy using after-loading machine: Pulsed or high-dose rate?
Cancer/Radiothérapie, 2014Since February 2014, it is no longer possible to use low-dose rate 192 iridium wires due to the end of industrial production of IRF1 and IRF2 sources. The Brachytherapy Group of the French society of radiation oncology (GC-SFRO) has recommended switching from iridium wires to after-loading machines.

Low dose rate versus high dose rate intraluminal brachytherapy for malignant endobronchial tumors
Radiotherapy and Oncology, 1995Although the evolution from low dose rate to high dose rate brachytherapy for malignant endobronchial malignancies was primarily based on economy, patient convenience, and radiation protection, the difference in therapeutic index, if any, between these two modalities must be kept in mind.

High dose rate brachytherapy for prostate cancer
Cancer/Radiothérapie, 2008High 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 ...
