A quantitative FLASH effectiveness model to reveal potentials and pitfalls of high dose rate proton therapy

Abstract

Our model provided a quantitative measure of the FLASH effect for various delivery and patient scenarios, supporting previous assumptions about potentially promising planning approaches for FLASH proton therapy. Positive clinical benefits compared to clinical plans were achieved using hypofractionated, single-field transmission plans. The dose threshold was found to be an important factor, which may require more investigation.
