Leksell Gamma Knife Icon to Benefit More Patients with Brain Disease

Latest iteration features advanced motion management, dose delivery

May 28, 2015 — With the introduction of Elekta's new Leksell Gamma Knife Icon, the benefits of precision cranial radiosurgery are now available for more patients with a wider variety of tumor types and sizes. This latest generation stereotactic radiosurgery system for the brain integrates advanced motion management, dose delivery and imaging technologies, significantly increasing the versatility of Gamma Knife radiosurgery. Elekta unveiled Leksell Gamma Knife Icon at the 3rd European Society for Therapeutic Radiology and Oncology (ESTRO) Forum in Barcelona.

Icon provides increased flexibility by allowing physicians to choose either frame-based or frameless methods to immobilize the patient's head, in addition to the option to perform the treatment in a single session or multiple sessions (fractions or hypofractionation). The system even enables clinicians to choose the degree of precision needed for each patient's case – ranging from traditional radiosurgery accuracy to ultra-precise microradiosurgery.

"With Leksell Gamma Knife Icon, we expect two major changes," said Prof. Jean Regis, a neurosurgeon and Gamma Knife program director at University Hospital La Timone (Marseilles, France). "First, the system will increase indications, in the sense that we will be able do more hypofractionation. The second great benefit of Icon is the ability to do true adaptive radiosurgery both interfraction and intrafraction. It has the capacity to detect and measure position changes – to automatically propose dose planning adaptation – while providing the operator with an estimate of the influence of these corrections for validation."

Elekta developed Icon to be the preferred modality to treat almost any intracranial target. It offers new functionality familiar to radiation oncologists, such as cone beam computed tomography (CBCT), which should help increase the adoption of radiosurgery.

Leksell Gamma Knife Icon is not for sale or distribution in the U.S. and is not CE marked.
