About

M. Iwabuchi is a researcher specializing in medical physics and radiation oncology, with a primary focus on improving the accuracy of image-guided robotic radiosurgery. Their key research area centers on respiratory motion tracking, a critical challenge in treating moving tumors, particularly in the lungs and liver. Iwabuchi’s major contributions include the development of a system using beam’s eye view images to measure respiratory motion tracking errors in the CyberKnife Synchrony Respiratory Tracking System (SRTS). This work, published in 2015 and cited 19 times, demonstrated that the accuracy of the SRTS is patient-dependent, relying on the correlation between internal tumor position and external marker position, as well as predictive algorithms. In a subsequent 2019 study with 15 citations, Iwabuchi further investigated factors affecting tracking accuracy, providing insights that help clinicians optimize treatment plans. These studies have had a tangible impact on improving the precision of radiosurgery for mobile tumors, reducing the risk of underdosing tumors or overdosing healthy tissue. Iwabuchi’s work is essential reading for students and researchers in radiation oncology, offering practical solutions to one of the field’s most persistent technical hurdles.
