Compact upright proton therapy for much faster treatments

A compact beam delivery system enabling ultra-fast dose delivery for upright proton therapy

NIH-funded research Massachusetts General Hospital · NIH-11294180

This project builds a smaller proton therapy beam-delivery system so people with cancer—especially children and those with moving tumors—can get treatments in seconds instead of minutes.

What this research studies

This project will make proton therapy faster and more compact by using a new beam design (Fixed‑Field Alternating Gradient) and an ultra‑fast energy degrader. The team will build and test a full‑size degrader prototype, simulate the beam transport, and design the system to fit inside a single upright treatment room. Delivering each treatment field in a few seconds could help doctors treat tumors that move with breathing more accurately and reduce motion-related side effects. Shorter sessions and lower facility costs could make proton therapy more comfortable and available to more patients, including children.

Who could benefit from this research

Good fit: People whose cancers are treated with proton therapy—particularly pediatric patients and those with tumors that move with breathing—would be the most likely candidates for related clinical validation or future treatments.

Not a fit: Patients whose cancers are not managed with proton therapy or who already do well with conventional radiotherapy may not see direct benefit from this technology in the near term.

Why it matters

Potential benefit: If successful, patients could have much shorter treatment sessions, improved accuracy for moving tumors, and wider access to proton therapy at lower cost.

How similar studies have performed: Compact proton systems and beam‑delivery improvements exist, but combining FFA lattices with an ultra‑fast degrader for upright, single‑room treatment is relatively novel and early‑stage.
