Ionization Detail to Improve Particle Therapy Planning

Official title: Ionization Detail - Biologically based treatment planning for particle therapy beyond LET-RBE

Funded at University of California, San Francisco · NIH-11406282 · Data updated 2026-11-12

Aims to use a new measure called ionization detail to better predict how different ion beams affect biology, with the goal of improving treatment plans for proton and carbon therapy.

Who could benefit from this research

Could help

Patients receiving proton or carbon therapy who could benefit from more accurate and personalized treatment planning.

Less likely to help

Patients not receiving particle therapy or those not eligible for adaptive planning studies may not directly benefit.

What this research studies

This project from UCSF seeks to replace or augment current planning methods that rely on LET and conventional RBE models by using ionization detail to forecast tissue responses more accurately at the nanometer scale. The team will integrate ID into existing models to enhance dose prescriptions for charged-particle therapy. If successful, this could lead to more precise treatments and potentially better tumor control with fewer side effects. The work involves computational modeling and comparison of ID-based predictions with traditional approaches across different ion types and energies.

Why it matters

Potential benefit: If ID-based planning proves more accurate, patients could receive more effective treatments with reduced toxicity.

How similar studies have gone: Previous models show dose predictions can vary across different RBE models, but ID may offer improved accuracy; this is a novel approach with promising preliminary support.
