Radiation shielding and safety implications following linac conversion to an electron FLASH‐RT unit

open access: yesMedical Physics, 2021
AbstractPurposeDue to their finite range, electrons are typically ignored when calculating shielding requirements in megavoltage energy linear accelerator vaults. However, the assumption that 16 MeV electrons need not be considered does not hold when operated at FLASH‐RT dose rates (~200× clinical dose rate), where dose rate from bremsstrahlung photons

Beam Diagnostics for FLASH RT in the Varian ProBeam System

2022
FLASH RT is a novel ultra-high dose rate radiation therapy technique with the potential of sparing radiation induced damages to healthy tissue while keeping tumor control unchanged. Recent studies indicate that this so-called FLASH effect occurs when applying high doses of several Grays in a fraction of a second only, and thus significantly faster than

Testing Proton FLASH RT in Bone Mets

Cancer Discovery, 2022
Abstract Findings from FAST-01, a first-in-human trial of proton FLASH radiotherapy, indicate that this approach is safe and seems as effective as conventional radiation in relieving pain from bone metastases in the arms and legs, with no additional or unexpected toxicity.

News FLASH-RT: To Treat GBM and Spare Cognition, Fraction Size and Total Dose Matter

Clinical Cancer Research, 2021
Abstract Data indicate that ultrahigh dose rate (&gt;106 Gy/second) FLASH radiotherapy (FLASH-RT) delivery of radiation reduces normal tissue damage without compromising tumor response. Orthotopic glioblastoma mouse studies now demonstrate that radiation fraction size, total dose, and number of fractions are critical parameters for ...
