Leksell Gamma Knife® Esprit – The Evolution of Gamma Knife for Modern Neuroradiosurgery

Leksell Gamma Knife® Esprit is not just a new generation of Gamma Knife, but a technological evolution of the entire Elekta stereotactic radiosurgery platform.
Compared to previous generations, Esprit expands clinical capabilities by combining submillimeter Gamma Knife precision, frameless and frame-based workflows, integrated advanced planning, improved clinical efficiency for single and multi-fraction treatments, and greater adaptability for complex clinical scenarios.

Frameless and Frame-Based Treatment in a Single System

One of the key advantages of Gamma Knife® Esprit is support for both traditional frame-based and modern frameless workflows. This opens new opportunities for clinics:

• More flexible treatment protocol selection;
• Broader application of single-session and fractionated SRS;
• Better adaptation to anatomy, clinical objectives, and patient condition;
• Higher patient comfort without compromising accuracy.

Submillimeter Precision of Gamma Knife – Esprit

Maintains the key advantage of the Gamma Knife platform — exceptional dose delivery accuracy for intracranial targets. The system uses 192 simultaneous high-energy gamma beams, ensuring:

• High conformity of dose distribution;
• Minimization of dose to healthy tissues;
• Ability to treat small, multiple, and anatomically complex targets;
• High confidence when working near critical structures.

Expansion of Clinical Scenarios

Previous Gamma Knife generations were primarily focused on single-session frame-based radiosurgery. Esprit expands this concept and better meets modern neuroradiosurgery requirements.
The platform is especially valuable for centers working with:

• Multiple brain metastases;
• Large lesions near critical structures;
• Benign skull base tumors;
• Functional indications;
• Cases requiring greater flexibility in treatment strategy.

Enhanced Patient Comfort

Compared to previous Gamma Knife generations, Esprit offers a more modern patient-centered approach.
This is especially important in cases where mask-based / frameless workflow is appropriate, allowing:

• Reduced psychological burden;
• Expanded possibilities for treatment personalization;
• Improved overall treatment experience.
