Fast helical imaging and treatment delivery for superior patient outcomes.

Image-guided radiation therapy (IGRT), featuring best-in-class clinical workflows and highly conformal treatments enabled by a unique ultra-fast multi-leaf collimator (MLC) for precise delivery of intensity modulated radiation treatments (IMRT) and stereotactic body radiation therapy (SBRT) treatments.


Confidence in planning and delivering adaptive treatments.


Continuous 360o precision driving clinical efficiency.


Precisely treating virtually any indication and complexity.


Key Features and Benefits



ClearRT® produces clear, high-fidelity kVCT images to provide soft-tissue visualization for precise image registration, localization, and adaption. ClearRT® enables you to see more, know more, and do more.


Fast and simple planning experience

VOLO™ Ultra enables you to accelerate treatment planning and delivery with intuitive, automatic planning methods to streamline workflows.


Flexible treatment delivery

Treatment options for a wide range of cases:
  • TomoHelical™ continuous, rotational beam delivery
  • TomoDirect™ fixed step and shoot beam delivery


Real-time adaptive radiotherapy

Synchrony® enables real-time motion management with intrafraction imaging and AI-driven treatment delivery to precisely adjust the treatment to the tumor in real-time.


Superior control of dose delivery

360° treatment beam delivery with intensity modulation provides homogenous conformal dose painting and enhanced beam-shaping thanks to the ultra-fast multi-leaf collimator and dynamic jaws.


Integrated and automated surface-guided radiotherapy (SGRT)

VitalHold™* package provides a solution for patient setup and patient monitoring. It also enables deep inspiration breath hold (DIBH) treatments with TomoDirect treatment delivery.
