“The CyberKnife® System achieves the same accuracy as frame-based radiosurgery. But, it uses image-guided robotics to avoid the need for a frame,” said Walter M. Sahijdak, M.D., radiation oncology specialist at SJMHS. “This approach is not only less invasive for treatments of head tumors, but has also made radiosurgery possible throughout the body. The key is that CyberKnife® requires no frame.”
