What is Robotic Stereotactic Radiosurgery, e.g. Cyberknife Stereotactic radiosurgery is a precise, painless, non-invasive radiation treatment that utilizes very accurately targeted, large killing doses of radiation. This non-invasive operation has proven to be an effective alternative to surgery or conventional radiation for treating many small tumors and a few other select medical disorders. CyberKnife Centers of Tampa Bay provide a number of online videos and case studies to help you understand more about the CyberKnife technology. Multiple beams of high energy radiation are delivered from multiple points outside of the body and converge precisely at the tumor or lesion inside the body. Each individual beam is not sufficient to cause harm, but the convergence of all the beams at the tumor results in the lesion receiving a very high dose of radiation while sparing nearby normal tissue. CyberKnife radiosurgery is so precise, radiation beams can be sculpted to small, complex-shaped tumors near critical structures, such as hearing and vision nerves. This ability to accurately irradiate only the tumor and protect healthy tissue allows the CyberKnife to treat many lesions which may be considered inoperable or untreatable with other radiosurgery systems giving many patients new hope. Standard stereotactic techniques rely on a rigid metal frame fixed to a patient s skull for head immobilization and target localization. However, such frame-based systems have numerous limitations, including: Restricting treatment to the brain, Limiting the possible angles which radiation could be delivered, Causing considerable discomfort for the patient. In contrast to the standard frame-based radiosurgical instruments, the CyberKnife uses noninvasive image-guided localization, and a robotic delivery system. This combination of technologies enables the CyberKnife to overcome the limitations of older frame-based radiosurgery such as the Gamma Knife and LINAC The CyberKnife be...
