HealthEast CyberKnife Center at St. Joseph's Hospital has been offering CyberKnife treatment since 2003 and was the first in the Upper Midwest to offer this groundbreaking technology. CyberKnife® is the first system in the world to offer full-body radiosurgery. It can be used to treat tumors and lesions that were formerly inoperable.
Refer a patient to HealthEast CyberKnife Center
We are committed to working with referring physicians to give your patients an effective treatment option for malignant and benign tumors and lesions. CyberKnife treats tumors and lesions that are unreachable or untreatable with conventional surgery or other stereotactic radiosurgery methods.

Where to send records
If you have a patient who may be a candidate for CyberKnife treatment, please send records (including imaging exams) for evaluation to:
St. Joseph's Hospital CyberKnife Center 45 West 10th Street St. Paul, MN 55102
CyberKnife is FDA-approved for use throughout the body and offers non-invasive treatment of:
Brain tumors and lesions
- Skull base tumors
- Metastases (brain and bony)
- Nasopharyngeal carcinomas
- Acoustic neuromas
- Pituitary adenoma
- Other benign tumors
- Arteriovenous malformations (AVMs)
- Cavernous malformations
- Trigeminal neuralgia
Extracranial tumors and lesions
- Base of skull
- Cervical spine
- Thoracic spine
- Lumbar spine
- Other lesions, tumors and conditions anywhere in the body where radiation treatment is indicated
Two revolutionary technologies
The CyberKnife system combines two revolutionary technologies — advanced image guidance and robotics. An image guidance system that uses cruise missile technology tracks and verifies the tumor's location. This enables automatic compensation for patient movement during treatment delivery.
A multi-jointed robotic arm with six degrees of freedom provides unmatched maneuverability in targeting tumors. A high-energy x-ray source mounted on the robotic arm precisely locates the position of the tumor in the body and delivers pinpoint radiation from more than 1,200 angles.
Customized treatment plans
CyberKnife allows for customization of each patient's treatment plan. Its flexible arm makes a wider range of treatment plans possible, including either forward or inverse treatment planning. CyberKnife treats tumors and lesions that are unreachable or untreatable with conventional surgery or other stereotactic radiosurgery methods.
Advantages of CyberKnife
CyberKnife technology provides a number of advantages over conventional radiotherapy, including:
- Ability to treat multiple tumors at different locations during a single treatment
- Focused, maximum radiation to the tumor without affecting surrounding healthy tissue
- Treatment for tumors that are inoperable by conventional surgery and other stereotactic radiosurgery methods
- Reduction in the risk of complications such as infections, hemorrhage and the loss of hearing/feeling sometimes associated with conventional surgery
- Improved patient comfort (no invasive head frame is required)
- Procedure is done on an outpatient basis
- Treatment is painless and requires no recovery time
- Treatment sessions are generally 30 to 90 minutes long
- Most conditions can be treated in just one to five treatments
CyberKnife's accuracy represents a major advance in radiosurgery. Digital radiographic images of anatomical features or implanted fiducials (markers) are used to precisely target the radiation. The focused radiation beams converge at the tumor with sub-millimeter accuracy to maximize the amount of radiation that reaches the tumor and minimize exposure to surrounding healthy tissues.
