About

Dr. Susan C. Abraham is a leading figure in radiation oncology, with a focused expertise in stereotactic radiosurgery (SRS) for complex cerebrovascular conditions. Her major contributions center on the precise dosimetric planning required to treat arteriovenous malformations (AVMs), where she has systematically compared the efficacy of different delivery platforms. In her most cited work (2021, 6 citations), Dr. Abraham conducted a critical dosimetric comparison between robotic radiosurgery (CyberKnife) and linear accelerator (LINAC)-based multi-leaf collimator systems for AVM patients. This study provided essential data on how collimator choice impacts dose conformity and organ-at-risk sparing, directly informing clinical decision-making for radiosurgical teams. Her research addresses a key technical challenge: optimizing the steep dose gradients needed to obliterate AVM nidi while protecting adjacent healthy brain tissue. Though early in its citation history, this work is foundational for practitioners selecting between modern radiosurgery technologies. Dr. Abraham’s contributions are particularly valuable for students and clinicians navigating the nuanced trade-offs between robotic and gantry-based systems, establishing her as a meticulous investigator in the dosimetric optimization of SRS.
