Radiation machine that expands radiotherapy treatment like no other system in the world.

The next-generation TomoTherapy® platform delivers: IG-IMRT treatments with the most streamlined clinical workflows and fully integrated radiotherapy treatment planning. 

A Single Radiotherapy Treatment Platform to Revolutionize Your Practice

Patients reeling from diagnoses need precise and effective treatment to get their lives back. Radiotherapy treatment teams need next-level precision and efficacy to improve patient outcomes. Radixact, the latest TomoTherapy platform allows you to treat a broad range of indications with advanced features such as ClearRT™, Synchrony® and VOLO™ Ultra. Its fast helical imaging and treatment delivery make the Radixact System the perfect solution for any clinic that want to take advantage of faster more personalized, and more universal treatments.


Personalized delivery in sync with target motion for every indication

The revolutionary Synchrony® technology* uses intrafraction imaging and AI-driven treatment delivery to adapt the delivery beam position to the tumor location precisely, accurately and at all times during the delivery of a treatment fraction. This enables no-tradeoff radiation therapy: continuous, uninterrupted dose delivery with tight margins and steep dose gradients while the patient behaves naturally. With Synchrony technology, clinicians are freed to choose the fractionation schedule that best meets their patients’ clinical needs, knowing that effectiveness and efficiency of their treatment will remain unhindered.

The expected outcomes? Shorter treatments, fewer side effects and higher quality of life.

*Synchrony technology is an optional upgrade available for purchase by hospitals.


For the full range of oncology patients

The Radixact System is designed to provide unprecedented flexibility and provides treatment options for a wide range of possible indications:

  • Rotational and non-rotational radiation therapy
  • Image-guided, intensity-modulated radiation therapy (IG-IMRT)
  • Innovative TomoHelical™ rotational delivery mode
  • TomoDirect™ non-rotational delivery mode
  • TomoEDGE™ dynamic dose sculpting mode

Treat all breast cancer cases with the Radixact® System

VitalHold™ Breast Package* allows you to provide deep inspiration breath hold (DIBH) treatments using TomoDirect treatment delivery mode on the Radixact System through the fully integrated and automated surface-guided radiation therapy (SGRT) solution. The Radixact System offers compromise-free capabilities to treat the full spectrum of breast cases in as little as 2 minutes, leveraging both TomoHelical (helical delivery) and TomoDirect (tangential beams). The Radixact System with VitalHold allows for easy patient compliance enabling higher breast cancer patient throughput for clinics.
