Edge® Radiosurgery SystemClinical Benefits

Sub-Millimeter Accuracy*

Accurate delivery of highly conformal dose distributions and steep gradients is the hallmark of the Edge radiosurgery system. Every step of the Edge treatment is characterized by high-level accuracy so treatments can be delivered with confidence. Calibrated to perform accuracy checks every 10 milliseconds, the Edge treatment process is characterized by precision so treatments can be delivered safely and with confidence. The use of Monte Carlo equivalent algorithms for dose calculations, extra-fine 2.5mm MLC leaves for beam shaping, real-time tracking for direct target localization, and beam specifications that are amongst the tightest in the industry, all join together putting treatment with Edge in a category of its own. A streamlined evolution from traditional surgery, Edge offers QA tools to help ensure faster delivery conformality while minimizing the dose received by surrounding healthy tissues. Dedicated to quickly and accurately delivering radiosurgery, Edge integrates the highest dose rate with non-ionizing, direct and real-time guidance for target location. The large dose level is designed to maximize the amount of radiation to the targeted area while minimizing the amount of time patients spend being treated. Advanced automation helps clinicians guide and maintain the accuracy of treatment delivery by continually tracking patient movements and adapting treatments as the target moves. This feature can potentially decrease the risks of unwanted dose to surrounding healthy tissues. The reliability and precision of Edge radiosurgery allows every patient to feel confident because they are treated according to plan.

Fast Treatments

Leveraging the highest dose rate in the industry, 2400 MU/minute, treatments on the Edge system allow for short treatment times, enhancing patient comfort. The use of RapidArc® radiosurgery technology makes it possible to use the Edge system to deliver SRS and SBRT treatments typically in a standard radiotherapy treatment slot. Clinicians may deliver precisely sculpted 3D dose distribution to single lesions or multiple mets for stereotactic ablation of inoperable and high-risk operable tumors. RapidArc radiosurgery, powered by Eclipse™ treatment planning system, enables planning specifically for radiosurgery treatments with automatic, easy to use contouring tools. As a result, fast, accurate treatment delivery can not only help improve patient comfort by reducing the amount of time a patient spends on the treatment couch, but may also result in a lower overall peripheral dose.

Digital Architecture and Automation

Edge’s real-time system architecture enables a high level of synchronization between the functional capability of the gantry, collimator and couch. Having a carefully guided, workflow automation using intuitive visual cues to enhance safety and reduce operation times, Edge optimizes patient throughput. By streamlining imaging and patient positioning, Edge enables more treatment flexibility to treat a wide variety of cases throughout the body wherever radiation is indicated. Having the power to not only treat quickly, but to deliver high, accurate dose rates are hallmarks of the Edge system.
