About
Ioannis Seimenis is a leading researcher at the intersection of medical physics, robotics, and interventional radiology, with key contributions in two distinct but impactful domains: precision dosimetry for radiosurgery and the development of MR-compatible robotic systems for minimally invasive procedures. In the field of medical physics, his most cited work (64 citations) experimentally determined critical correction factors for microchamber and diode detectors when measuring output factors for the CyberKnife iris collimator’s small fields, directly improving the accuracy of stereotactic radiosurgery dose delivery. His broader, pioneering focus, however, is on enabling interventions under direct MRI guidance. He has designed and prototyped novel, manually actuated and concentric tube robotic manipulators that are both magnetically and geometrically compatible with the MRI environment, addressing the severe constraints of scanner bore access and magnetic field interference. His work integrates preoperative planning, real-time control, and even holographic interfaces for immersive image guidance. With over 140 total citations across his portfolio, Seimenis has established foundational principles for MR-compatible robotic design, bridging the gap between advanced imaging and precise, robot-assisted therapy.
