Colorado CyberKnife has adopted the “best-in-class” technologies (CyberKnife and Tomotherapy) to treat candidates for Radiotherapy and Radiosurgery as well or better than other treatment modalities (surgery, proton therapy, chemotherapy, brachytherapy, davinci, gammaknife,…) at a fraction of the cost.
The CyberKnife System offers a expanding set of options that help track tumor types anywhere in the body — including head, prostate, lung, spine, liver, pancreas and other extracranial tumors. Our treatment delivery software provides an automatic, intuitive user interface to efficiently control all interactions between the robotic manipulator, treatment couch and imaging system. The software quickly and automatically processes live images acquired throughout treatment at user-defined intervals, calculates offsets based on Digitally Reconstructed Radiographs (DRRs) and sends offset data to the robotic manipulator for immediate and automatic motion compensation.
Depending on the type of tumor being treated, the CyberKnife System will use different targeting and tracking methods:
- 6D Skull Tracking System: renders invasive stereotactic head frames obsolete, by using the bony anatomy of the skull to continuously track intracranial targets and automatically correct for even the slightest translational or rotational target shift during treatment delivery.
- Synchrony® Respiratory Motion Tracking System: This solution continuously synchronizes beam delivery with the motion of the target resulting from respiration, without the need to interrupt the treatment or move the patient. It allows clinicians to significantly reduce margins, while eliminating the need for gating or breath-holding techniques.
- Xsight® Spine Tracking System and Xsight Spine Prone Tracking System: use the bony anatomy of the spine to automatically locate and track tumors, eliminating the need for surgical implantation of fiducials and making radiosurgery in and near the spine more precise and less invasive. With the Xsight Spine Prone feature, the benefits of non-invasive spine treatments can be extended to patients in prone, as well as the supine, position.
- Xsight Lung Tracking System and 1-View Tracking System: work together with the Synchrony® Respiratory Motion Tracking System to eliminate the need to implant fiducials. These solutions directly and non-invasively track the lung tumors independently of their position.
- InTempoTM Adaptive Imaging System: uses the CyberKnife System’s time-based image guidance to assist with tracking and correcting non-predictable intrafraction target motion.
- Lung Optimized Treatment is an integrated suite of tools that provides a complete fiducial-free clinical solution for lung cancer patients and optimizes non-invasive lung SBRT treatments. Lung Optimized Treatment consists of the following features:
- Simulation Application is a workflow-based application that automatically recommends the optimal choice for fiducial-free treatment of lung tumors based on specifics of clinical conditions.
- 1-View is a tracking method that works in conjunction with Synchrony Respiratory Tracking System. 1-View tracks lung tumor motion in one of two X-ray projections allowing accurate dose delivery with radiosurgical margins in the tracked direction. Under this scenario ITV expansion is applied in the non-tracked X-ray projection.
- 0-View is a treatment method that applies in situations when a lung tumor is not clearly visible in either X-ray projection. 0-View uses ITV expansion in two X-ray projections and Xsight Spine Tracking System to track patient position.
What Exactly is the CyberKnife System?
The CyberKnife System is a robot that delivers a unique form of Stereotactic Body Radiation Therapy (SBRT) also known as radiosurgery. It is the only radiation therapy technology that tracks tumor motion and automatically corrects the aim of the treatment beam when movement is detected. The CyberKnife Radiosurgery System delivers radiation with sub-millimeter accuracy through the use of continual image guidance and robotic mobility. As a result, the radiation is directed to where it counts most, the prostate, and the radiation dose falls off steeply around the healthy tissue that surrounds the prostate.
Colorado CyberKnife physicist Brian Thorndyke, PhD explains what CyberKnife Robotic Radio Surgery is, how it works, how it compares to surgery and brachytherapy, and whether or not CyberKnife might be your best cancer treatment option.
Colorado Cyberknife is one of a few facilities in the world to offer the latest non-invasive radiation treatment, with the next-generation Cyberknife VSI unit, which brings revolutionary advantages to our patients. We also boast the region’s leading radiosurgery doctors.
Destroying tumor cells – stopping tumor growth
CyberKnife is a new approach to stereotactic radiosurgery. In general, stereotactic radiosurgery is a non-surgical treatment that uses 3-D imagery to aim multiple radiation beams on a specific location inside the body in order to destroy a tumor. Stereotactic radiosurgery can precisely target tumors and avoid damage to the surrounding healthy tissue and structures. Unlike surgery, stereotactic radiosurgery destroys the tumor cells and stops the growth of the tumor without removing it. The Gamma Knife, another stereotactic radiosurgery system which is used on brain tumors, requires the patient be secured to an invasive head-frame to ensure the patient remains perfectly still during the treatment. Colorado CyberKnife’s pioneering technology offers all of the advantages of stereotactic radiosurgery, without the need to have the patient secured to a head or body frame to control movement.
Creating personalized treatment plans
Before treatment begins, the CyberKnife computer uses a CT scan (and possibly MRI and PET scans) to create a 3-D image that precisely locates the tumor. The CyberKnife-certified radiation oncologist and medical physicist use the CyberKnife treatment planning computer to evaluate the unique shape, size and location of the tumor, as well as the tissue and structures that need to be protected. The result is a personalized treatment plan for each patient that prescribes how much radiation will be used and how each beam of radiation will target the tumor.
Delivering radiation with pin-point accuracy
Throughout the treatment, image guidance cameras automatically locate and track the position of the tumor, and the system automatically corrects for any patient or tumor movement. During the procedure the patient lies comfortably on the table while the computer-controlled robotic arm moves around the patient and the X-ray machine delivers converged beams of radiation to precisely defined areas from a variety of angles and multiple positions. The CyberKnife system uses a high-energy X-ray machine on the robotic arm to deliver the radiation beams that will kill the tumor cells.
Targeting tumors from virtually any angle
The robotic arm is very flexible, which provides pin-point accuracy from virtually any direction. Colorado CyberKnife can treat tumors that cannot be treated by surgery or other radiation therapies, or cannot be treated without damaging surrounding tissue and structures.
Synchronizing to patient and tumor movement
The Colorado CyberKnife Center has the most current CyberKnife VSI technology that employs the Synchrony Tracking System to synchronize radiation beam delivery to the motion of the tumor. This tracking system eliminates the need for breath-holding techniques, or head/body frames, to stabilize patient movements. Throughout the treatment, image-guidance cameras automatically locate and track the position of the tumor, and the system automatically corrects for any patient or tumor movement. This highly sophisticated technology is particularly beneficial in the treatment of lung, prostate, liver, pancreas, kidney and other abdominal or thoracic tumors that move when the patient breathes. The level of accuracy available with translates to a more comfortable treatment experience for the patient and greatly improved treatment results.
RoboCouch Patient Positioning System
Robotically enables faster patient setup. The benefit that RoboCouch offers patients is that it enables simple and comfortable loading of mobility-limited patients and patients up to 500 lbs. We are the only Cyberknife facility in the state of Colorado that has the RoboCouch! Learn more about the RoboCouch benefits.
