About
Dennis Yuen-Kan Ngar is a leading expert in stereotactic image-guided radiation therapy (IGRT), with a focus on precision quality assurance (QA) for advanced treatment systems. His most notable contribution is the development of a novel compound 6D-offset simulating phantom and accompanying QA program, designed to commission and routinely test 6D IGRT systems. This work, published in 2013, provides a comprehensive method for evaluating the accuracy of systems like the BrainLAB IGRT integrated with a Varian Clinac, addressing a critical need for verifying the six degrees of freedom in patient positioning. While his highly specialized work has garnered 8 citations, its impact is significant within the medical physics community, offering a practical tool that enhances the safety and precision of stereotactic treatments. Ngar’s research bridges the gap between phantom design and clinical workflow, ensuring that the complex geometric offsets in IGRT are accurately simulated and measured. His contributions are essential for physicists and clinicians seeking robust QA protocols for high-precision radiotherapy, underscoring his role in advancing the reliability of image-guided cancer treatments.
