The effect of irradiation at extremely high dose-rates
The British Journal of Radiology, 1969Berry, Hall, Forster, Storr and Goodman (1969) have reported some very interesting results which indicate an apparent lower effectiveness of radiation exposure when delivered at extremely high dose-rates. Using in any one experiment a single pulse of given very short duration and varying the dose received by the cells within this brief pulse, they ...

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

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 ...

[Brachytherapy for prostate cancer: high dose rate or low-dose rate?].
Cancer radiotherapie : journal de la Societe francaise de radiotherapie oncologique, 2006Low-dose brachytherapy for prostate cancer was actually proposed in the first years of the XXth century. Its modern version (iodin 125 or palladium 103 permanent implants) now benefits from some 15 years of experience in a few pioneer centers, with very satisfactory results in term of efficacy/toxicity ratio.

Pulsed dose rate (PDR) brachytherapy is a new type of afterloading brachytherapy (BT) in which a continuous low dose rate (LDR) treatment is simulated by a series of "pulses," i.e., fractions of short duration (less than 0.5 h) with intervals between fractions of 1 to a few hours. At the Dr.

AbstractBackgroundUltra high dose rate (UHDR) radiotherapy using ridge filter is a new treatment modality known as conformal FLASH that, when optimized for dose, dose rate (DR), and linear energy transfer (LET), has the potential to reduce damage to healthy tissue without sacrificing tumor killing efficacy via the FLASH effect.PurposeClinical ...

Postoperative High-Dose-Rate Brachytherapy in the Prevention of Keloids
International Journal of Radiation Oncology*Biology*Physics, 2007The aim of this study is to show the efficiency of keloidectomy and postoperative interstitial high-dose-rate (HDR) brachytherapy in the prevention of keloids.Between 1998 and 2004, 35 patients with 54 keloids were treated postoperatively with HDR brachytherapy.

High dose rate versus low dose rate brachytherapy for gynecological cancer
Seminars in Radiation Oncology, 1993High dose rate (HDR) remote afterloading for the treatment of gynecologic cancers began about 30 years ago. The promising clinical results obtained have led to the establishment of hundreds of HDR facilities worldwide with tens of thousands of patients treated.
