Duo Adjust™ Cranial SRS Immobilization System for CyberKnife®

Immobilization for CyberKnife® intracranial SRS

DUO-ADJUST™ is an advanced cranial SRS immobilization system designed for CyberKnife® intracranial stereotactic radiosurgery (SRS). Combining the rigidity of the HEXPAND™ reinforced thermoplastic mask with instant shim adjustability, DUO-ADJUST™ provides efficient, dependable patient immobilization while maintaining standard CyberKnife® clinical workflows.

Engineered to support sub-millimeter setup accuracy, DUO-ADJUST™ helps clinicians achieve consistent patient positioning, maintain skull tracking performance, and preserve confidence in accurate 6 degrees-of-freedom (6DoF) setup. The result is a practical immobilization solution that enhances patient safety, workflow efficiency, and treatment precision for intracranial radiosurgery.
