CyberKnife Robotic Radiosurgery

CyberKnife can be used to treat benign and malignant tumors, as well as certain other non-cancerous conditions, anywhere in the body. It delivers beams of high-dose radiation with extreme accuracy, which offers new hope to patients who have inoperable or surgically complex tumors.

Its robotic design allows surgeons to manipulate the system to focus radiation to the shape of each tumor, effectively targeting the tumor and avoiding the surrounding healthy tissue. 

Due to this precision, CyberKnife can administer larger and more accurate doses of radiation over a shorter period of time. Typically, one to five treatments will be required with the CyberKnife system; other therapies typically require six to eight weeks of daily treatment.

The CyberKnife uses image-guidance software to detect any movement by the patient, even motions as miniscule as breathing, and adjust the treatment accordingly. 

CyberKnife causes very few side effects. In fact, most patients are able to return to their normal activities immediately following treatment. Other advantages include:

  • The treatment is painless

  • No anesthesia is required

  • The procedure is performed on an outpatient basis

  • The patient does not need to hold his or her breath during treatment
