About

Sohail Sayeh is a leading figure in the field of robotic radiosurgery, whose work has fundamentally shaped how clinicians treat moving tumors. His primary research focuses on advanced motion tracking and compensation systems, specifically the integration of robotics and real-time signal processing to overcome the challenge of respiratory motion during radiation delivery. Sayeh’s most impactful contribution is his pioneering role in the development of the Synchrony® Respiratory Tracking System, the motion-tracking subsystem of the CyberKnife® Robotic Radiosurgery System. His seminal 2007 paper, "Respiratory Motion Tracking for Robotic Radiosurgery," which has garnered 98 citations, details the core algorithms that enable a robotic manipulator to dynamically compensate for tumor movement. This work, alongside his 2019 technical overview of the CyberKnife system (53 citations), provides the foundational framework for the technology. Sayeh also explored fuzzy logic and hybrid prediction models to mitigate system delays, as seen in his 2007 paper on position signal prediction. Through these innovations, his research has directly enabled safer, more precise, non-invasive treatment for cancers in the lung, liver, and pancreas, establishing him as a key architect of modern stereotactic body radiation therapy.
