About
D. Choi is a medical physicist whose work centers on advancing the precision and safety of proton radiosurgery, a cutting-edge cancer treatment. Their research focuses on quality assurance (QA) methodologies for proton beam delivery, particularly in stereotactic radiosurgery. A key contribution is the development of end-to-end testing protocols using specialized phantoms, such as the Lucy 3D QA phantom, to verify the overall accuracy of treatment delivery with ready-made circular collimator inserts and fixed-thickness compensating boluses. This work addresses critical challenges in ensuring that proton beams are correctly targeted and dosed, minimizing risks to patients. Though their most cited paper, "SU‐E‐T‐268: Proton Radiosurgery End‐To‐End Testing Using Lucy 3D QA Phantom" (2014), has garnered 3 citations, its impact lies in establishing reproducible QA standards that enhance clinical reliability. Choi’s contributions are vital for the safe implementation of proton therapy, a field where even small errors can have significant consequences. Their meticulous approach to phantom-based testing underscores a commitment to bridging the gap between theoretical dosimetry and practical treatment delivery, making them a valuable figure in the ongoing refinement of particle therapy techniques.
