Pencil-beam method to deliver ultra-fast (FLASH) proton radiation

Project 4: Development and validation of Pencil Beam Scanning methodology for particle FLASH radiotherapy

NIH-funded research University of Pennsylvania · NIH-11298926

This project develops a way to use pencil-beam proton machines to give ultra-fast 'FLASH' radiation that could better target tumors while sparing healthy tissue.

What this research studies

This team is creating methods to deliver FLASH proton radiation using pencil beam scanning and will study how the timing and spatial pattern of the beams changes dose to tumors and nearby normal tissues. They will run laboratory and animal experiments, including work in canine models, to measure biological effects and build fast dose-recording instruments. The project will develop image-guided positioning, quality-assurance procedures, and end-to-end validation so treatments can be delivered accurately. The long-term aim is to adapt existing proton therapy systems so patients can access safer, ultra-fast radiation options.

Who could benefit from this research

Good fit: People with localized solid tumors who are candidates for proton therapy or for future clinical trials of FLASH radiation would be the most relevant candidates.

Not a fit: Patients with widespread metastatic disease, tumors not suitable for proton therapy, or those unable to travel to specialized proton centers are unlikely to benefit in the near term.

Why it matters

Potential benefit: If successful, this could allow much shorter proton treatments that reduce harm to healthy tissues and improve patient outcomes.

How similar studies have performed: Preclinical FLASH studies in animals have shown reduced normal-tissue damage, but using pencil-beam scanning to deliver FLASH is a newer approach that is largely untested in humans.
