Learn How We Spur the Future of Radiation Therapy Innovation

Radixact® System with Synchrony®

Real-Time Motion Synchronization

Over 15 years ago, Accuray revolutionized tumor and patient motion management with our Synchrony® real-time motion synchronization technology. Building on our proven expertise, we are bringing Synchrony* to the Radixact® System for real-time tracking and automatic motion synchronization. While others will use gating methods to compensate for motion, our Synchrony technology actively tracks and corrects for it. The expected outcomes? Shorter treatments, fewer side effects and higher quality of life.


Fiducial and fiducial-free targets cab be selected for tracking.


Advanced sequential kv imaging, taken at any angle, detects target movement during treatment.


The system’s ultra-fast binary MLC and dynamic jaws synchronize the treatment beam position to the newly detected or predicted target position in real-time — without any interruption of treatment.

CyberKnife® VOLO Optimizer

Over 95% Reduction in Optimization Time, up to 50% Faster Delivery

We recently unveiled the latest patient-first innovation from Accuray: the new CyberKnife® VOLO Optimizer – the next-generation treatment planning optimizer for the CyberKnife System.

Watch CyberKnife VOLO – the Next-generation Treatment Planning Optimizer in Action

Resource Flexibility: Easy to learn and intuitive to use, the CyberKnife VOLO Optimizer can be used by any planner to quickly and easily create excellent treatment plans eliminating the need for dedicated planning staff.

Efficient Planning: The CyberKnife VOLO Optimizer has been tuned to perform predictably to user inputs, so planning is consistent and reproducible with optimization performed in seconds or minutes. It allows all users to produce high quality treatment plans, quickly, easily and on the first attempt.

Efficient Treatment Delivery: With increased efficiency for treatment planning and delivery, the VOLO Optimizer makes the CyberKnife System an even more versatile tool – enabling practices to treat more patients and a wider range of indications with sub-millimeter robotic precision, even for tumors that move. The CyberKnife VOLO Optimizer automatically optimizes the number of non-coplanar beams, reducing movement of the robot, and enabling the delivery system to deliver plans up to 50% faster than previously possible with better quality. SRS/SBRT treatments for a single fraction can be delivered in times comparable to IMRT treatments on a standard LINAC.

Next-generation CTrue IR Image Guidance

Iterative Reconstruction for Superior 3D Imaging

Ease of Registration: Iterative reconstruction reduces noise, enabling clinicians to easily distinguish anatomical features and ensure optimal patient positioning

Facilitate Plan Adaptation: Achieve the best possible outcomes for your patients by accurately adapting treatment doses to clearly delineated anatomy

<1 cGy per Image*: The same low-dose 3D imaging you have come to expect on the TomoTherapy® platform, up to 60% faster on the Radixact® System

Live Image Reconstruction: No waiting for clinical images, and now fewer steps required to acquire images from fraction to fraction

*Imaging dose using “Coarse” scan mode, which is typically used for most patients.
