In Vivo Measurements of Hydrated Electron Production with an Ultra-High Dose Rate (UHDR) Electron Beam

Authors: Xu Cao, Wesley S. Culberson, Aubrey Parks, Brian W Pogue, William Scott Thomas

Affiliation: Department of Medical Physics, School of Medicine and Public Health, University of Wisconsin - Madison, University of Wisconsin-Madison, University of Wisconsin - Madison, UW-Madison

Abstract Preview: Purpose:
The hydrated electron is a critical reactive species generated during the radiolysis of water when ionizing radiation interacts with biological tissues. It plays a pivotal role in mediatin...

Investigating X-Ray Flash Effect on Plasmid DNA with Combined Microscopic Monte Carlo and Analytical Simulations

Authors: Xun Jia, Youfang Lai

Affiliation: Department of Radiation Oncology and Molecular Radiation Sciences, Johns Hopkins University, Johns Hopkins University

Abstract Preview: Purpose: Ultrahigh dose rate FLASH (>40 Gy/s) radiotherapy (RT) has attracted significant attention. The mechanism remains unclear, hindering clinical translation. This study investigated the behavior...

Investigating the Radiation Chemistry of Flash Radiation Therapy through Electron Paramagnetic (EPR) Spectroscopy

Authors: Ramin Abolfath, Alexander Baikalov, Stefan Bartzsch, Nolan M. Esplen, Alan Eduardo Lopez Hernandez, Emil Schueler

Affiliation: MD Anderson Cancer Center, PI Experimental Medical Physics, Institute of Radiation Medicine (IRM), Helmholtz Munich, Germany, Howard University, Department of Radiation Physics, The University of Texas MD Anderson Cancer Center

Abstract Preview: Purpose: FLASH radiation therapy (FLASH-RT) leverages ultra-high dose rates (UHDR) to spare normal tissue as compared to conventional (CONV)-RT while preserving tumor control; this is termed the FLASH...
