Versatile, efficient and effective for the range of radiation oncology patients.

Image-guided, intensity-modulated radiation therapy (IG-IMRT) featuring streamlined clinical workflows and fully integrated treatment planning.

Personalized, precise cancer treatment — for the full spectrum of radiation therapy patients.

The TomoTherapy® System is among the most revolutionary innovations in the history of cancer treatment, completely redefining the standard for individualized and precise treatment of tumors anywhere in the body — while creating a new paradigm for patient comfort and quality of life.

The first truly complete IGRT/IMRT solution, TomoTherapy combines integrated CT imaging for exceptional treatment accuracy with a first-of-its-kind helical treatment delivery platform that uses patented beam-shaping technology to precisely target tumors while minimizing impact on surrounding healthy tissue. Ongoing investment in innovation enhances the trusted and proven platform, as Accuray continues to elevate imaging and beam-shaping capabilities to new levels.

Treatment delivery

The first true helical imaging and delivery platform.

The TomoTherapy® System empowers uniquely personalized radiation therapy. The transformative TomoTherapy radiation platform is the first to combine CT imaging with a unique ring gantry platform, setting a new standard for precision treatment delivery across the full spectrum of indications and radiation therapies — including image-guided, intensity-modulated radiation therapy (IG-IMRT) and 3D conformal radiation therapy (3DCRT).
