AlignRT® is a system of cameras, mounted to the ceiling, that sends information about your body’s position into a software program.
Each camera unit uses a projector and image sensors to
create a 3D surface model of the area by projecting a red light (containing a speckle pattern) on your skin. The speckled pattern allows AlignRT® to reference thousands of points on the skin, acting as virtual tattoos.
The system constantly monitors you and turns off the radiation beam along with alerting your therapist if you move out of the desired position.
