Expands treatment like no other system in the world

Image guided, intensity modulated radiation therapy (IG-IMRT), featuring best-in-class clinical workflows and highly conformal treatments enabled by a unique ultra-fast multi-leaf collimator (MLC). The Radixact® System shapes radiation to the tumor while sparing normal, healthy tissue.

Proven radiation therapy platform. Radically expanded capabilities.

Patients reeling from diagnoses need precise and effective treatment to get their lives back. Radiotherapy treatment teams need next-level precision and efficiency to improve patient outcomes. Clinical practices need to deliver value-based care and treat a broad range of indications with superior outcomes. The Radixact® Treatment Delivery System enables all of this with a fully integrated platform for intelligent treatment planning, centralized data management and ultra-precise treatment delivery of SBRT and IMRT treatments.  The Radixact System uses refined x-ray beamline and a unique high-speed multi-leaf collimator, combined with fast ClearRT™ helical fan-beam kVCT imaging to deliver treatments for patients with a wide variety of individual treatment needs — and now features Synchrony® real-time delivery adaptation for targets that move during delivery.


Continuous 360o precision
driving clinical efficiency.

Integrated clinical workflows, accelerated imaging, planning and delivery enable clinicians to achieve highly precise and fast treatments.​


Confidence in planning and delivering adaptive treatments.

Integrated helical fan-beam kVCT imaging, real-time motion synchronization and automated adaptive planning and dose monitoring make highly personalized, real-time adaptive radiotherapy treatment practical for every clinic and every patient.


Precisely treating virtually any indication and complexity.
