About
Dr. Alexandra Hellerbach is a leading researcher in stereotactic radiosurgery, with a focus on optimizing treatment for brain tumors and vestibular schwannomas. Her key contributions lie in refining response criteria and treatment planning for CyberKnife® robotic radiosurgery. In her highly cited 2023 paper (27 citations), she proposed new response criteria for distinguishing pseudoprogression from true tumor progression in vestibular schwannomas after radiosurgery—a critical challenge that affects patient management and follow-up decisions. Dr. Hellerbach also advanced the field of radiotoxicity prediction by developing a quality index to minimize the brain volume receiving 12 Gy (V12), a key predictor of radionecrosis, thereby improving treatment plan safety for brain metastases. Her work on dose homogeneity and collimator selection (2021) further clarified how prescription isodose levels influence plan quality, providing practical guidance for clinicians. Through these studies, Dr. Hellerbach has established herself as an authority on radiosurgery physics and clinical outcomes, directly impacting how radiation oncologists optimize tumor control while reducing complications. Her research bridges the gap between technical planning parameters and meaningful patient outcomes.
