About
Keisuke Tamari is a medical physicist whose research sits at the intersection of robotic radiosurgery, real-time tumor tracking, and precision dosimetry, with a particular focus on the CyberKnife Synchrony™ system. His work has made meaningful contributions to understanding and mitigating the sources of error that arise during image-guided stereotactic treatments. Tamari's most-cited study (27 citations) rigorously examined how respiratory phase shifts compromise the accuracy of motion-tracking models that correlate internal tumor position with external LED surrogates — a clinically critical insight for thoracic and abdominal treatments. Complementing this, his investigations into intra-fraction prostate motion and liver SBRT correlation errors have deepened understanding of how target displacement translates into dosimetric consequences for patients. He has also advanced detector methodology, evaluating plastic scintillation detector calibration techniques for small-field CyberKnife dosimetry, and developed robust frameworks for delivery quality assurance. His clinical research on stereotactic ablative body radiotherapy for metastatic lung tumors further bridges technical precision with patient outcomes. Collectively, Tamari's body of work, spanning quality assurance, motion management, and treatment delivery accuracy, provides an essential evidence base for physicists and clinicians striving to maximize the therapeutic precision of robotic radiosurgery.
