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, 1974
Irradiation 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...

Modifying a clinical linear accelerator for delivery of ultra-high dose rate irradiation

Radiotherapy and Oncology, 2019
The purpose of this study was to modify a clinical linear accelerator, making it capable of electron beam ultra-high dose rate (FLASH) irradiation. Modifications had to be quick, reversible, and without interfering with clinical treatments.Performed modifications: (1) reduced distance with three setup positions, (2) adjusted/optimized gun current ...

Characterizing devices for validation of dose, dose rate, and LET in ultra high dose rate proton irradiations

Medical Physics
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 ...

Survival of mammalian cells exposed to X rays at ultra-high dose-rates

The British Journal of Radiology, 1969
Abstract X irradiation delivered in single, nanosecond-length pulses, so that the instantaneous dose-rate exceeded 7 × 1010 rads/second, was less effective in abolishing the subsequent reproductive capacity of HeLa and Chinese hamster cells in vitro than was irradiation delivered at lower dose-rates.

Toxicity of hadrontherapy at ultra-high dose rate

Toxicité de la hadronthérapie à ultra-haut débit de dose La radiothérapie à Ultra-Haut Débit de Dose (RT-UHDD), de l’ordre du Gray/msec, est une technique prometteuse pour réduire la toxicité aux tissus sains. Par ailleurs, la balistique des hadrons (protons/ions d'hélium) permet un meilleur ciblage des tumeurs, limitant la dose ...
