The CyberKnife® Robotic Radiosurgery System is the world’s first and only robotic radiosurgery system designed to treat malignant and non-malignant tumors throughout the body non-invasively. As an alternative to traditional surgery, there’s absolutely no cutting—which means no pain and minimal recovery time. Unlike some other radiosurgery systems, which can only treat tumors in the head, the CyberKnife System has unlimited reach to treat a broad range of tumors throughout the body, including the head, spine, lungs, prostate, liver and pancreas. For patients who have inoperable or surgically complex tumors, or who may be looking for an alternative to surgery, it offers a new ray of hope.

The USA Medical Center CyberKnife System (CyberKnife System), located in the same building as MCI, offers tremendous advantages over traditional surgery and other radiosurgery systems. As a non-invasive, outpatient procedure, the treatment is completely pain free. It requires no anesthesia, no recovery time, and, in most cases, patients can return to normal activity immediately following the treatment.

Because the CyberKnife System uses sophisticated image guidance software to continually adjust treatment for any patient movement, patients can breathe normally and relax comfortably during treatment. Furthermore, it does not require any rigid head frames or other extreme procedures to keep patients in place. And it’s ability to treat tumors with pinpoint accuracy and spare surrounding healthy tissue is unmatched by any other type of surgery or radiation therapy.

USAMCI radiation oncologists are highly experienced in CyberKnife treatments and are members of the national CyberKnife Society and hold numerous other designations in radiation oncology.

The CyberKnife Treatment Process


Prior to treatment with the CyberKnife System, the patient undergoes imaging procedures to determine the size, shape and location of the tumor. The process begins with a standard high-resolution CT scan, or for certain tumors other imaging techniques, such as MRI, angiography or PET, may also be used.

Following the scanning, the image data is then digitally transferred to the CyberKnife System’s treatment planning workstation, where the treating physician identifies the exact size, shape and location of the tumor. A qualified clinician then uses the CyberKnife software to generate a treatment plan to provide the desired radiation dose to the identified tumor location while avoiding damage to the surrounding healthy tissue. The patient does not need to be present during this step in the process.

During a CyberKnife procedure, a patient lies comfortably on the treatment table, which automatically positions the patient. Anesthesia is not required, as the procedure is painless and non-invasive. The treatment generally lasts between 30 and 90 minutes and is typically completed in one to five visits.

During treatment, a patient can be allowed to take short “breaks”. After a break, the patient simply returns to the treatment room and treatment proceeds without extensive re-positioning.
