Executive Industry Relevance

Quantitative assessment of acute radiation-induced skin toxicity remains a critical gap in translational radiation therapy research, limiting predictive confidence and objective evaluation of normal tissue response. Diffuse optical spectroscopy (DOS) offers a reproducible, high-throughput approach to generate functional optical biomarkers, supporting mechanistic de-risking and target validation for interventional strategies. Integrating DOS-derived metrics into preclinical and clinical workflows enhances portfolio decision-making and risk-adjusted advancement of radioprotective agents.
