The cyber-knife produced by the American company Accuray was installed in the MIBS center in 2011. Our doctors were trained in the best clinics in Europe and the USA. Over the course of five years nearly 3,000 operations were performed on the Cyber-knife unit.
To date, more than 50,000 patients around the world have benefited from exceptional tumor treatment options provided by Accuray cyber-knife system. Among these people are those whose tumors were formerly considered inoperable or required complex surgical intervention.
Cyber-knife is the first and only in the world robotic radiosurgical system, designed to treat benign and malignant tumors in any place of the body with unique accuracy. This is a modern non-invasive treatment method, which is an alternative to surgical treatment. The device delivers high radiation doses directly to the tumor, significantly reducing the risk of radiation damage to healthy tissues.
The system consists of a compact linear accelerator with an energy of 6 MeV, located on a robotic console, having six degrees of freedom and providing 1200 beam positions during irradiation. The robot manipulator provides movement and guidance of a linear accelerator with high (submillimeter) accuracy.
Treatment on a cyber-knife does not require anesthesia. The procedure can be performed on an outpatient basis, moreover, it is beneficial for patients who have contraindications for traditional radiotherapy or surgery. To accommodate out-of-town patients, the Center has a day hospital with 50 places.
Preparation for treatment
Treatment with Cyber-knife is preceded by scanning of a tumor or other pathological formation to determine its size, shape and location. Usually scanning begins with a standard CT scan of high resolution (HRCT). To visualize some neoplasms, other methods can also be used: MRI, angiography or PET diagnostics.
Images obtained during the scanning process are digitally transferred to the Cyber-knife planning system, where the physician determines the exact size, shape and localization of the lesion. Based on these data, a qualified doctor develops a plan of therapy with the help of special software. When planning, the necessary dose of radiation is calculated to avoid damage to the healthy tissues surrounding the tumor. At this stage, presence of the patient is not required.
During the procedure, the patient in a comfortable position is located on the medical table, which is automatically positioned relative to the Cyber-knife console. Anesthesia is not required, as the operation on the Cyberknife is painless and non-invasive (does not require injections, incisions and other penetrations into the body). The standard duration of one session (fraction) is 30 to 90 minutes. When irradiated, one or more fractions are used. The cost of treatment, as a rule, is fixed regardless of their number.
At the end of treatment, patients may experience mild fatigue, which is often associated with relief from an emotional stress due to the successful completion of treatment. The day after radiosurgery, most patients return to their normal everyday life and professional activities.
A detailed interview is conducted with the patient and his relatives about recommendations for follow-up, treatment, lifestyle and medical documentation on the radiosurgery performed is issued. In case of any questions, patients can always contact the doctors of our center by phone or e-mail.
The main method of postoperative monitoring is magnetic resonance imaging, performed with contrast enhancement. Employees of the Radiosurgical Center with the help of a special program perform a very accurate overlaying of preoperative and postoperative images to compare them. The scans taken in the MIBS diagnostic centers meet all the requirements necessary for assessing the dynamics. You just need to tell us that this examination is a follow-up procedure after radiosurgical treatment and have an extract about the operation performed available. The received images will be sent via the telemedicine network to St. Petersburg, and in three days you will be able to discuss the results of your treatment by phone with the doctors of the radiosurgical center.
If you perform an MRI not in the MIBS diagnostic centers, then you need to alert the staff of the MRI center about the following requirements for the examination:
The examination is performed with contrast enhancement.
The thickness of the slices does not exceed 3 mm.
The image matrix must be square.
Pictures should be recorded on CD in DICOM format.
