About

Z. Grelewicz is a medical physics researcher whose work centers on robotic motion correction and quality assurance in radiation therapy, with a particular focus on stereotactic radiosurgery (SRS). Their most influential contribution, a 2014 paper on the development of a six degree-of-freedom (6DOF) robotic motion phantom, garnered 20 citations and established a critical framework for testing and validating advanced patient tracking technologies used in modern radiotherapy. Building on this foundation, Grelewicz pioneered real-time robotic systems capable of correcting both translational and rotational head motion during frameless SRS procedures — a significant advancement over traditional frame-based techniques, which had long been considered the gold standard for spatial accuracy. Their 2015 work on feedback and feed-forward control algorithms demonstrated that non-invasive, high-precision motion correction was achievable without sacrificing targeting accuracy. Complementing these engineering contributions, Grelewicz also developed novel quality assurance methodologies for evaluating 6DOF patient tracking systems, ensuring clinical reliability. Collectively, their publications reflect a sustained effort to make frameless radiosurgery safer and more precise, with a combined citation record that underscores growing recognition of their innovations within the medical physics and radiation oncology communities.
