Rocky Mountain CyberKnife was the eighth installed CyberKnife system in the United States and is nationally ranked. The RMCK team has treated hundreds of patients using the latest CyberKnife technologies.

We work very closely with Accuray, the maker of CyberKnife, and are an active participant in the continued enhancement of the technology. Our system and team are always on the cutting edge. Rocky Mountain CyberKnife was a leader in the development of the Synchrony Respiratory Tracking System which is the only radiosurgery system in the world that identifies tumor position throughout the treatment and synchronizes treatment delivery to the motion of the tumor throughout the respiratory cycle. Rocky Mountain CyberKnife has performed more Synchrony Cyberknife cases then any other center in the nation.

Synchrony Respiratory Tracking System
The Synchrony System will allow physicians, for the first time, to treat their patients with much tighter margins, no longer having to add significant margins to compensate for a moving target, thus sparing more healthy tissue.

Synchrony uses a complex system of cameras, motion tracking software, fiber optic sensing technology, infrared emitters and a special formfitting, highly elastic patient garment to do its job. In conjunction with CyberKnife, the system identifies, updates and then correlates external body surface movement with movement of the internal tumor fiducials. Throughout the procedure, Synchrony is monitoring the target and readjusting its calibrations to assure that it is locked on the tumor. The result is that physicians know exactly where the tumor is in real time, and can use maximum radiation without fear of harming surrounding healthy tissues.

• Dynamically tracks all targets that move with respiration
• Improves accuracy of radiation delivery
• Minimizes irradiation of healthy tissue or critical structures
• Treats complex targets
• Eliminates painful breath-holding
• Eliminates complex gating techniques
• Decreases treatment times
• Simpler, more streamlined procedures

The Synchrony System simultaneously tracks both movement of the tumor and breathing patterns of the patient. The robotic arm adjusts and compensates for these movements ensuring more accurate treatment and eliminating breath-holding or gating requirements. A recent multi-center study reported targeting centroid accuracy better than 1.5mm.

Expanding accurate radiosurgery treatment to all tumors that move with respiration such as lung, pancreas, liver, kidney or other abdominal or thoracic tumors.

The Synchrony System permits patients to breathe normally throughout their treatment, without breath-holding or gating techniques

Xsight Spine Tracking System
Rocky Mountain CyberKnife has installed and performed numerous surgeries using the the Xsight™ Spine Tracking System, which integrates with the CyberKnife® Stereotactic Radiosurgery System. Xsight eliminates the need for surgical implantation of radiographic markers, or fiducials by using actual bony structure of the spine to orient and locate the lesion during the delivery of radiosurgery treatments for spinal tumors and tumors near the spine.

Xsight is effective for treating lesions throughout the spinal region—including cervical, thoracic, lumbar and sacral tumors. At present, more than 60 patients have been treated nationally with the CyberKnife System with Xsight, adding to the more than 1,600 spine radiosurgery cases that have been treated with the CyberKnife over the past four years. Xsight is another example of how the CyberKnife System expands the practice of Radiosurgery by offering a non-invasive cost effective alternative to surgery.
