Machine-learning models and shielding materials for radiation protection of patients and personnel in ion therapy
Compared to traditional external X-ray therapy, ion therapy uses heavy ions to improve dose conformality, increase biological effectiveness, and spare the healthy tissues surrounding the tumor volume. With these unique physical characteristics, ion therapy can maintain or even escalate the dose to …

High-Throughput Mapping of The Biological Effects of Particle Therapy
<p>Radiation therapy is an essential tool in the cure of many cancer patients. Charged particle based radiation therapies are gaining momentum as the physical dose distributions of ions are superior to standard photons due their limited range. Additionally, charged particle radiation has been shown …
