👥Biography 个人简介
Anders Brahme is a pioneer of biologically optimized radiation therapy and one of the most influential figures in the theoretical and practical understanding of proton therapy RBE uncertainty and its clinical implications. He developed the conceptual and mathematical framework for intensity-modulated radiation therapy (IMRT) optimization decades before it became clinical practice, and has been a leading voice on the need to account for variable proton RBE—particularly the elevated biological effectiveness at the distal Bragg peak—rather than using the fixed clinical value of 1.1. His LQ-based and microdosimetric kinetic models have shaped treatment planning for particle therapies.

🎓Key Contributions 主要贡献
IMRT Optimization Theory
Developed the theoretical framework for biologically optimized intensity-modulated radiation therapy in the 1980s, introducing inverse planning concepts and the use of biological objective functions that preceded and influenced clinical IMRT development worldwide.
Proton RBE Variable Modeling
Demonstrated through biophysical modeling and experimental data that the RBE of protons varies significantly with LET, dose, tissue type, and position along the Bragg peak, challenging the clinical convention of a fixed RBE of 1.1 and quantifying the potential biological hot spots at the distal edge.
Microdosimetric Kinetic Model for Particle Therapy
Extended the microdosimetric kinetic model (MKM) to account for particle track structure effects on cell killing, providing a mechanistically grounded framework for predicting RBE across the LET spectrum from protons to carbon ions.
