About

Elizabeth Bossart is a leading medical physicist whose research centers on stereotactic body radiation therapy (SBRT) and radiosurgery, with a particular focus on optimizing treatment delivery for lung and spine tumors. Her seminal work, "CyberKnife® Radiosurgery for Stage I Lung Cancer: Results at 36 Months" (2007, 86 citations), established critical benchmarks for non-invasive, high-precision radiation treatment of early-stage lung cancer, demonstrating durable tumor control and setting the stage for widespread clinical adoption. Bossart has also made significant contributions to spine SBRT, where she systematically evaluated dosimetric properties of linear accelerator and CyberKnife platforms to maximize tumor dose while protecting nearby organs-at-risk. Her comparative analyses have directly informed clinical protocols, helping radiation oncologists choose the most effective technology for individual spine cases. With a career dedicated to advancing the accuracy and safety of stereotactic treatments, Bossart’s work has been instrumental in translating cutting-edge radiation physics into tangible patient benefits, making her a respected authority in the field of therapeutic radiology.
