About
Alex W. Lightstone is a leading medical physicist whose research centers on stereotactic radiosurgery (SRS) and radiotherapy, with a particular focus on head immobilization and cone-beam CT (CBCT) analysis. His most-cited work, "To frame or not to frame?" (2018, 62 citations), provides a critical, CBCT-based evaluation of frameless head immobilization systems for linac-based SRS. This study systematically quantifies the reproducibility and intrafractional motion of noninvasive systems, offering essential guidance for clinicians balancing patient comfort with the submillimeter precision required for safe SRS delivery. By directly comparing frameless and frame-based approaches, Lightstone’s research helps define the clinical thresholds for motion management, directly impacting treatment planning margins and patient outcomes. His contributions are foundational for centers transitioning to frameless workflows, ensuring that technological advances do not compromise treatment accuracy. With a citation count reflecting its practical significance, this work remains a key reference for medical physicists and radiation oncologists seeking evidence-based protocols for head immobilization in high-precision radiotherapy.
