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.

Dose determination in high dose-rate brachytherapy
International Journal of Radiation Oncology*Biology*Physics, 1992Although high dose-rate brachytherapy with a single, rapidly moving radiation source is becoming a common treatment modality, a suitable formalism for determination of the dose delivered by a moving radiation source has not yet been developed. At present, brachytherapy software simulates high dose-rate treatments using only a series of stationary ...

High Dose Rate Prostate Brachytherapy
2021High Dose Rate (HDR) brachytherapy is a safe and effective method of treating men with prostate cancer. It is used in the definitive setting as monotherapy or in combination with hormonal therapy and/or external beam radiation therapy. It is also used in the salvage setting for local recurrence after primary radiotherapy.

High dose rate brachytherapy source measurement intercomparison
Australasian Physical & Engineering Sciences in Medicine, 2017This work presents a comparison of air kerma rate (AKR) measurements performed by multiple radiotherapy centres for a single HDR 192Ir source. Two separate groups (consisting of 15 centres) performed AKR measurements at one of two host centres in Australia.

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 ...

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 ...

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.

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.

High-dose-rate-Brachytherapie beim Risikoprostatakarzinom
Der Urologe, 2006Beim Prostatakarzinom ist zur Einschatzung des Therapieerfolgs hinsichtlich der rezidivfreien Zeit die Gruppierung in Niedrig-, Intermediar- und Hochrisikokarzinome sinnvoll. Die Trias PSA ≥10, Gleason-Score ≥7 und die klinische Tumorkategorie cT3 (extrakapsulares Tumorwachstum) sind bei der Einteilung hilfreich und einfach.
