The CyberKnife System is the world’s first and only radiosurgery system designed to treat tumors anywhere in the body with sub-millimeter accuracy. St. Luke Radiation Therapy and Cyberknife Center is the only center in Houston to offer Cyberknife Radiosurgery.

Watch this short video of Dr Carpenter describing the Cyberknife Radiosurgery System:


Stereotactic radiosurgery is a precise, painless, non-invasive radiation treatment that utilizes very accurately targeted, large “killing” doses of radiation. This non-invasive treatment has proven to be an effective alternative to surgery or conventional radiation for treating many small tumors and other select medical disorders.

Using image guidance technology and computer controlled robotics, the CyberKnife System is designed to continually track, detect and correct for tumor and patient movement throughout the treatment.

Because of its extreme precision, the CyberKnife System does not require invasive head or body frames to stabilize patient movement, vastly increasing the system’s flexibility. Traditional radiosurgery systems have limited mobility and generally require the use of rigid frames attached to a patient’s skull to provide a coordinate system to effectively target a tumor, restricting their ability to effectively treat tumors outside of the brain. The CyberKnife System does not have these limitations and, therefore, has increased flexibility to treat tumors throughout the body from many different directions, while minimizing the delivery of radiation to healthy tissue and vital organs.

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 options.

The CyberKnife procedure requires no anesthesia, can be performed on an outpatient basis and allows for the treatment of patients that otherwise would not have been treated with radiation or who may not have been good candidates for surgery. In addition, the CyberKnife procedure avoids many of the potential risks and complications that are associated with other treatment options.
