Our market-leading SGRT solution

AlignRT is at the center of Vision RT’s Surface Guided Radiation Therapy (SGRT) solutions. It’s a system that tracks a patient’s position before and during radiation therapy, to aid in setup and treatment accuracy. An entirely non-invasive and contact-free technology, AlignRT uses 3D stereo cameras to track the skin’s surface and compare it to the ideal position in the treatment plan with submillimetric† accuracy. It can automatically signal for the treatment delivery system to pause the radiation beam if the patient moves out of the desired position, and it eliminates the need for radiation therapy tattoos or headframes and closed masks for SRS.

AlignRT has been shown to help deliver “optimal patient positioning”, across many different cancer treatment sites. Many clinics first adopt SGRT because of its advantages in delivering Deep Inspiration Breath-hold treatments, but it can be used for every patient and for every fraction. There are already more than 200 peer-reviewed clinical studies on the effectiveness of SGRT with AlignRT and Vision RT’s systems are being used in all 15 of the top 15 US News “Best Hospitals for Cancer*”

We have comprehensive interoperability and assured long-term collaboration with both of the major linac vendors.
