About

Ren Hui Gong is a leading researcher in the field of medical physics and radiation oncology, with a primary focus on advancing image-guided radiotherapy for liver cancer. His most notable contribution is the development of a robotic 4D ultrasound (US) guidance system for liver stereotactic ablative body radiotherapy (SABR), a pioneering work that addresses the critical challenge of intrafractional tumor motion during treatment. In his landmark 2016 study, Gong and his team designed a system that enables real-time US imaging concurrent with radiotherapy beam delivery, incorporating sophisticated beam avoidance algorithms to prevent interference with volumetric modulated arc therapy (VMAT). This work demonstrated that robotic US guidance could be deployed in a significant proportion of liver SABR cases without compromising treatment delivery, achieving 20 citations and establishing a new paradigm for motion management in abdominal radiotherapy. Gong's research bridges the gap between advanced robotics and clinical oncology, offering a non-invasive, real-time solution to improve treatment accuracy and reduce toxicity. His contributions have profound implications for enhancing the safety and efficacy of stereotactic body radiotherapy, making him a key figure in the evolution of adaptive radiation therapy.
