Vision RT Compatible masks are open-faced masks for use with Surface Guided Radiation Therapy (SGRT), approved in partnership with various leading mask manufacturers.

You can recognize masks that are Vision RT Compatible when you see the above logo on the mask’s packaging or marketing materials.

With SGRT, SRS is performed while the patient is wearing an open-faced thermoplastic mask. This enables the patient’s movement to be monitored at all times and at all angles, by tracking the surface of the skin in real time. If the patient moves out of the desired treatment position, the radiation beam can be automatically paused.

Vision RT’s frameless SRS solution is proven to be accurate across several independent studies¹ and has published patient outcomes data comparable to more invasive techniques², while delivering greater patient comfort and fast treatment times. By listing open-faced masks as Vision RT Compatible, the company is confirming that these masks, when used correctly, can work as part of a procedure with AlignRT. This is intended to simplify customers’ choice of mask vendor.
