Leksell Gamma Knife® Icon™
Radiosurgical Precision
As a leader in brain radiosurgery, Elekta has introduced a new concept in radiosurgery for treating virtually all brain formations with the new Leksell Gamma Knife Icon system. Gamma Knife Icon is the most accurate radiosurgical device on the market and the only system with microradiosurgery technology.
At the same time, the Leksell Gamma Knife® Icon™ system further reduces radiation dose to healthy tissues. The Icon™ system also provides a number of innovations in the Gamma Knife product line, such as integrated imaging, software for continuous dose delivery control, and the ability to perform treatment without invasive fixation methods, while maintaining the same high level of radiosurgical precision. Given the growing demand for radiosurgical treatment, Icon makes the Gamma Knife system more flexible and easier to use, allowing more departments to establish brain radiosurgery in oncology clinics.
DoseControl™ In-Treatment Adaptation System
The DoseControl™ in-treatment dose control system is the most comprehensive approach to treatment quality control, providing real control of dose delivery accuracy. Integration of dosimetric control during treatment ensures continuous quality control throughout the entire irradiation session and allows clinical decisions to be made in real time.
Real-Time Position Tracking
In the new Gamma Knife Icon system, an identical level of dose delivery accuracy is achieved with any fixation method - both when using a frame and with frameless fixation, with an accuracy of 0.15 mm, which is 6 times higher than the standard of existing systems. If the patient's position goes beyond the acceptable accuracy, the system locks, instantly stopping dose delivery.
Online Dose Delivery Control
The unique integrated stereotactic Cone Beam CT imaging system is a new addition to the Icon radiosurgical system. Integrated with the patient positioning system, the CBCT system determines stereotactic coordinates in 3D, taking into account the patient's anatomy. After matching the Cone Beam CT image with the previously obtained MRI image, the treatment plan is automatically adapted. Thanks to the unique dose delivery characteristics, the system automatically adapts to changes in patient position. Online dose assessment allows comparing the dose distribution that should be delivered versus the dose you planned to deliver during the treatment session, which is done right at the console, and if necessary, the plan can be easily and quickly adapted online.
System Adaptation of Your Choice
Frame or frameless fixation, image-guided treatment or marker-based workflow, single-session or fractionated treatment, standard radiosurgery or high-precision microradiosurgery – the choice is yours.
The Leksell Gamma Knife system provides high treatment accuracy regardless of the fixation method, ensuring equally high precision for both frameless and frame-based treatment. This distinguishes the Icon system from all other systems on the market.
Unprecedented Precision — For Every Case
All components of the Gamma Knife system are integrated into a single system providing high precision of the radiosurgical system, which today represents the highest threshold of radiosurgical treatment accuracy, and according to documented data is 0.15 mm in real clinical conditions. In addition, none of the radiosurgical systems known today can compare with the Gamma Knife system in terms of preserving healthy tissues from radiation exposure. The unique design with isocentric planning and treatment allows you to make sure that the dose is exactly where you need it and has no effect on other areas of the brain. When treating with the Icon system, the dose to normal brain tissue is typically 2-4 times lower than when using other technologies. The extracranial dose is in an even lower range compared to other systems, which is 10-130 times lower than when using other systems.
Regardless of the immobilization method, the Leksell Gamma Knife Icon system provides the highest accuracy and steep dose gradient fall-off outside the irradiation area. Thus, the Leksell Gamma Knife Icon system provides high accuracy regardless of the chosen immobilization method.
