Characterization of a diode dosimeter for UHDR FLASH radiotherapy

Medical Physics, 2023
BACKGROUND: Ultra-high dose rate (UHDR) FLASH beams typically deliver dose at rates of \u3e40 Gy/sec. Characterization of these beams with respect to dose, mean dose rate, and dose per pulse requires dosimeters which exhibit high temporal resolution and

Effects of UHDR and Conventional Irradiation on Behavioral and Cognitive Performance and the Percentage of Ly6G+ CD45+ Cells in the Hippocampus

International Journal of Molecular Sciences, 2023
We assessed the effects of conventional and ultra-high dose rate (UHDR) electron irradiation on behavioral and cognitive performance one month following exposure and assessed whether these effects were associated with alterations in the number of immune ...

A simulation study of ionizing radiation acoustic imaging (iRAI) as a real‐time dosimetric technique for ultra‐high dose rate radiotherapy (UHDR‐RT)

Medical Physics, 2021
PurposeElectron‐based ultra‐high dose rate radiation therapy (UHDR‐RT), also known as Flash‐RT, has shown the ability to improve the therapeutic index in comparison to conventional radiotherapy (CONV‐RT) through increased sparing of normal tissue ...

Optically stimulated luminescence system as an alternative for radiochromic film for 2D reference dosimetry in UHDR electron beams

Physica Medica, 2023
: Radiotherapy is part of the treatment of over 50% of cancer patients. Its efficacy is limited by the radiotoxicity to the healthy tissue. FLASH-RT is based on the biological effect that ultra-high dose rates (UHDR) and very short treatment times ...
