Definition of vaginal doses in intrauterine high–dose-rate brachytherapy
Brachytherapy, 2004The aim of this study was to evaluate dosimetric aspects of high-dose-rate (HDR) intrauterine brachytherapy applications and to discuss a possible definition of vaginal points for dose reporting.HDR brachytherapy was performed using a "Fletcher-like" applicator. Doses to the vaginal mucosa were assessed using 2 sets of points for each ovoid.

Chromosome Breakage at High Radiation Dose-Rates
Nature, 1958THE variation of the frequency of chromosomal aberrations as a function of radiation dose-rate has been the subject of numerous experimental investigations, and the results of such studies have been of considerable importance in formulating theories of the basic mechanisms of radiation action1. With the recent availability of radiation sources of great

Cervix cancer brachytherapy: High dose rate
Cancer/Radiothérapie, 2014Cervical cancer, although less common in industrialized countries, is the fourth most common cancer affecting women worldwide and the fourth leading cause of cancer death. In developing countries, these cancers are often discovered at a later stage in the form of locally advanced tumour with a poor prognosis.

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 ...

To compare the outcomes for endometrial carcinoma patients treated with either high-dose-rate (HDR) or low-dose-rate (LDR) brachytherapy.This study included 1,179 patients divided into LDR (1,004) and HDR groups (175). Patients with International Federation of Gynecology and Obstetrics (FIGO) surgical Stages I-III were included.

High-dose-rate versus low-dose-rate intracavitary brachytherapy for carcinoma of the cervix
International Journal of Radiation Oncology*Biology*Physics, 1990High-dose-rate (HDR) remote afterloading intracavitary brachytherapy has been widely used in the treatment of carcinoma of the cervix in Europe and Asia since the 1960's. Recently, there has been an increase of interest in the use of this technique in North America.

Low-dose-rate brachytherapy is superior to high-dose-rate brachytherapy for bladder cancer
International Journal of Radiation Oncology*Biology*Physics, 2004To determine the efficacy and safety of a high-dose-rate (HDR) brachytherapy schedule in the treatment of bladder cancer and to investigate the impact of different values of repair half-times and alpha/beta ratios on the design of the HDR schedule.Between 2000 and 2002, 40 patients with T1G3 and T2 bladder carcinoma were treated with 30 Gy external ...

Oxygen Depletion in Cells Irradiated at Ultra-high Dose-rates and at Conventional Dose-rates
International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine, 1974Irradiation at conventional dose-rates of an oxygen-equilibrated bacterial cell suspension in a sealed vessel produces breaking survival curves similar to those observed for cells irradiated as a t...

High-dose rate brachytherapy for carcinoma of the cervix
Current Opinion in Oncology, 1993Increasingly popular in Europe and Asia as the intracavitary component for cervical cancer radiotherapy, high-dose rate brachytherapy demonstrates certain advantages over historical low-dose rate treatments. High-dose rate intracavitary treatment improves radiation safety, lessens treatment times, allows for outpatient treatment regimens, and has ...

Use of the dichromate solution as a dosimeter for high dose and high dose rate
Radiation Physics and Chemistry, 1996Abstract The radiolytic reduction of Cr(VI) in N 2 O-saturated aqueous solutions has been investigated over a large range of pH by steady state radiolysis. At pH 3 in the presence of formate as scavenger for ·OH, G(−Cr(VI)) is higher than the expected yield and a strong dose rate effect is observed.
