Halcyon 3.0 is a radiation cancer treatment device developed by US company Varian and is recognized as the most sophisticated treatment platform. The advantages of Halcyon 3.0 are that all parts of the treatment device maximize on patient comfort and safety. It is designed with an enclosed gantry and a collision detection technology which detects and prevents collisions resulting in precise and accurate care.


Particularly, it is optimized for Volumetric Modulated Arc Therapy (VMAT) based on real-time image guidance and can generate Cone-beam CT images that can accurately confirm the patient's treatment position within 16 seconds.


In addition, a dual-layer multi-leaf collimator is applied to generate less interleaf leakage compared to the existing radiation therapy device. Furthermore, as the gantry rotation speed is 4 times faster than the existing linear accelerator, the treatment speed is also increased, thereby reducing error caused by patient movement during radiation therapy.


With the introduction of the new radiotherapy system, Halcyon 3.0, along with linear accelerator, tomotherapy, and proton therapy, Samsung Medical Center is equipped with the finest radiation therapy system in Korea.
