What is AlignRT®?

AlignRT® is an innovative technology which increases treatment accuracy and patient comfort during radiation therapy.

Quickly growing in use around the world, AlignRT® uses a 3D camera system to track your body surface in real time and may be used to help position you accurately before radiation therapy, and ensure you keep that position during treatment.  Using your external skin surface, the technology monitors your movement and knows exactly where you are at any moment to within a fraction of a millimeter. AlignRT® can be used from head to toe.

Why should I choose a center with AlignRT® for my radiation therapy treatment?

The American Society for Radiation Oncology (ASTRO) issued treatment guidelines for breast cancer patients in 2018. These guidelines state that, “Approaches that incorporate deep inspiration breath hold, target and organ-at-risk contouring and optimal patient positioning are recommended to minimize the radiation dose affecting nearby organs and normal tissue, including the heart, lungs and opposite breast.”1   (our emphasis)

AlignRT® has been shown to help deliver this “optimal patient positioning”, across many different cancer treatment sites, and is commonly used for “deep inspiration breath hold”. There are many scientific studies published in journals with an excellent reputation, describing the accuracy of this technique.

Vision RT systems are deployed in 70% of the top 50 US News “Best Hospitals for Cancer” and have been extensively studied with over 65 published clinical studies.
