HKSH Proton Therapy Centre is equipped with Hong Kong's first proton therapy system, a unique and cutting-edge radiotherapy facility with advanced image-guidance technology, marking a new milestone in the city's cancer treatment.

The key components of the proton therapy system include two 190-degree half-rotating proton therapy gantries equipped with spot scanning technology, a 4-magnet-ring synchrotron-based accelerator with a diameter of approximately four metres, and an advanced beam transport system in a first-of-its-kind vertically stacked formation.
