The CyberKnife® System is the first and only radiotherapy device that brings true robotic precision and real-time motion tracking and correction technology to prostate cancer treatment, giving you a non-invasive, non-surgical, pain-free treatment option with proven results. CyberKnife uses an approach called stereotactic body radiation therapy (SBRT), delivering precise doses of radiation with extreme accuracy — and accounting for target motion in real-time. This helps minimize the risk of side effects and helps to preserve your quality of life during and after treatment. This revolutionary treatment technology is not new; CyberKnife has more than a decade of clinical proof and has helped more than 20,000 men with prostate cancer.
