A new digital Cobalt-60 combined stereotactic radiotherapy and radiosurgery system, termed as the GyroKnife, was developed in Shanghai, China in 2004. The equipment integrates advantages of previous generations of gamma radiosurgery techniques and linear accelerators. The technology has the capacity for non-invasive whole-body stereotactic fractionated radiotherapy and single high-dose radiosurgery as well. Using a triple focussing method, high isocenter accuracy (0.5~1.0 mm) and minimal skin (550:1) or normal tissue irradiation dose were achieved with 4 various sizes of collimator sets (5, 15, 25, 50 mm). The first GyroKnife Center in Kang Da Hospital, Xiang Fan, China, has already treated 100 cases with different tumours in the brain and body since November 2006. The technical details of the system will be presented, and the preliminary clinical results will also be discussed.
