Differential tissue sparing of FLASH ultra high dose rates: an {\it in-silico} study

Ramin Abolfath, Alexander Baikalov, Sohrab Rahvar +4

Purpose: To propose a theory for the differential tissue sparing of FLASH ultra high dose rates (UHDR) through inter-track reaction-diffusion mechanism. Methods: We calculate the t…

Modeling interspur interactions as a potential mechanism of the FLASH effect

Alexander Baikalov, Ramin Abolfath, Radhe Mohan +3

The mechanism responsible for the FLASH effect, normal tissue sparing by ultra-high dose rate (UHDR) irradiation with isoeffective tumor control compared to conventional dose rate…

The effect of non-ionizing excitations on the diffusion of ion species and inter-track correlations in FLASH ultra-high dose rate radiotherapy

Ramin Abolfath, Alexander Baikalov, Stefan Bartzsch +2

We present a microscopic mechanism that accounts for the outward burst of "cold" ion species (IS) in a high-energy particle track due to coupling with ''hot" non-ion species (NIS).…

Optimization of FLASH Proton Beams Using a Track-Repeating Algorithm

Qianxia Wang, Uwe Titt, Radhe Mohan +4

Methods: A phase space file in a plane at 202 mm downstream of the beam exit window is generated through tuning parameters to match FDC results with measured or MCNPX Monte Carlo-s…

Oxygen depletion in FLASH ultra-high-dose-rate radiotherapy: A molecular dynamics simulation

Ramin Abolfath, David Grosshans, Radhe Mohan

We present a first-principles molecular dynamics (MD) simulation and expound upon a mechanism of oxygen depletion hypothesis to explain the mitigation of normal tissue injury obser…

A New Approach to Modeling the Microdosimetry of Proton Therapy Beams

Ramin Abolfath, Yusuf Helo, David J. Carlson +3

{\bf Introduction}: To revisit the formulation of the mean chord length in microdosimetry and replace it by the particle mean free path appropriate for modelings in radio-biology.…
