About

Robert Kaderka is a leading researcher in the field of medical physics, specializing in advanced motion management for particle therapy. His work focuses on the critical challenge of compensating for organ motion—particularly from breathing—during scanned ion beam therapy, ensuring precise dose delivery to moving tumors. Kaderka’s major contributions include pioneering the integration of real-time motion detection technologies for tumor tracking. He conducted foundational experimental studies demonstrating the feasibility of using correlation models to estimate tumor position from external surrogate markers, achieving effective motion compensation with millimeter precision. His research also broke new ground by evaluating diagnostic ultrasound as a real-time motion detection tool for ion beam tracking, a non-ionizing alternative to fluoroscopy. With his most-cited papers accumulating over 50 citations, Kaderka’s work has directly advanced the clinical implementation of motion mitigation techniques. Notably, he successfully integrated an infrared optical tracking system into a treatment control system for beam tracking, a key step toward making scanned ion therapy safer and more effective for extra-cranial lesions. His research remains essential for physicists and clinicians developing next-generation adaptive radiotherapy.
