Introducing Akesis Galaxy™ – The Rotating Gamma System

The Akesis Galaxy is a rotating gamma system that combines the proven efficacy of gamma radiation with state-of-the-art rotational technology to optimize treatment planning and delivery. The system’s dynamic, rotational delivery provides more coverage and the ability to shape the dose distribution as opposed to traditional, fixed sector-based delivery.


1. Modern Rotational Design

Over 2,000 beams available within a single arc for plan optimization.

2. Accuracy First

Radiology accuracy is <0.5mm through the device’s clinical life.**

3. In-Room Display

Thoughtfully placed within easy reach of the operator during patient setup, the display provides visual confirmation of the treatment plan and patient identity.

4. Automatic Collimation Changes

Collimator rotation of up to 4RPM with sizes of 4, 8, 14 and 18mm that are changed on the fly in accordance with the treatment plan.

5. Automatic Positioning System

3-D positioning integrated into the couch offers patient positioning accuracy with a reproducibility of <0.5mm.

6. Decreased Treatment Times

Treatment automation helps optimize the patient flow and increase patient comfort.

Akesis Galaxy Benefits

Combines a proven treatment modality with innovative technology to streamline intracranial stereotactic radiosurgery.

Allows you to design and deliver highly conformal treatments that lower the dose to healthy skin while reducing hot spots and dose peaks.

Dramatically reduces reload costs – without losing flexibility and precision in treatment performance.

  • 30 radiation sources
  • Simplified treatment delivery
  • Comprehensive service
  • Cost-effective source replacement
  • Robust reimbursement

More than one million patients* have been treated with the rotating gamma technology. With < 0.5mm radiologic accuracy, Akesis Galaxy also provides sharper dose fall-off, providing better sparing of organs at risk.

* Estimated patients treated with a rotating isometric design gamma system as reported by healthcare centers using the technology.
** AKESIS Galaxy will perform with a total radiological accuracy of <0.5mm when a valid service agreement is maintained.
