About

Cristina Sarti is a leading researcher in medical physics, specializing in real-time motion management for particle therapy. Her primary research areas include ultrasound-guided ion beam tracking, motion mitigation techniques in radiotherapy, and the development of precision imaging methods for cancer treatment. Sarti’s major contribution is pioneering the use of diagnostic ultrasound as a real-time motion detection tool for ion beam therapy, demonstrating that ultrasound imaging can track tumor position with millimeter precision—a critical advancement for improving treatment accuracy in moving targets like lung or liver tumors. Her most-cited work, "Ion beam tracking using ultrasound motion detection" (2014, 27 citations), established a foundational phantom-based study that validated this approach, paving the way for non-invasive, radiation-free motion monitoring. This work has significant implications for reducing healthy tissue damage and enhancing dose delivery in particle therapy. Sarti’s research bridges engineering and clinical oncology, offering a practical solution to one of radiotherapy’s greatest challenges: compensating for respiratory and cardiac motion. Her innovative use of ultrasound—a widely available, low-cost technology—positions her as a key figure in advancing accessible, real-time adaptive radiotherapy.
