About

Joshua A. James is a medical physicist whose research focuses on the precision and safety of stereotactic radiosurgery, particularly for lung tumors. His most-cited work, a 2014 study on planning target volume (PTV) margins in robotic radiosurgery with spine tracking, has garnered 11 citations and addresses a critical challenge: ensuring accurate tumor targeting despite respiratory motion. By quantifying the necessary margins when using spine-based tracking for lung lesions, James provided essential guidance for clinicians, reducing the risk of geographic miss while minimizing damage to healthy tissue. This contribution underscores his expertise in treatment planning optimization and motion management. His research bridges the gap between technological capability and clinical application, directly impacting patient outcomes in high-precision radiotherapy. James’s work is a valuable resource for students and researchers seeking to understand the interplay between tracking systems, target delineation, and dosimetric accuracy in modern radiosurgery.
