Research
A major focus of Dr. Yoon's work has been the evaluation and implementation of advanced radiotherapy technologies. He has explored the clinical feasibility of the Ethos online adaptive radiotherapy platform in a remote setting as part of a collaboration with Varian, assessing the auto-segmentation capabilities, dosimetric impact, and clinical workflow timing of the Ethos system for head and neck and gynecological cancer. This contributed to the practical integration of online adaptive radiotherapy into routine clinical practice with the goal of informing clinicians of its treatment precision and efficiency. In addition, he has conducted a pilot study investigating the use of a novel O-ring linear accelerator system (Halcyon) for prone breast tangential radiotherapy. This study, which assessed daily positional and dosimetric consistency, demonstrated the dosimetric robustness of prone-position whole breast radiotherapy planned with electronic tissue compensation and a flattening filter-free beam.
