In addition, we manufacture a multi-part carbon positioning system that, in combination with a custom-fitted face mask, enables millimeter-precise positioning of the head during treatment. At the heart of the system is the so-called Navigator — a carrier with reflective material pheres that are invisible in X-ray images but precisely detected in the operating room by an infrared 3D camera system. The Navigator is mounted on a precisely aligned carbon baseplate, known as the Baseplate. The software calculates a three-dimensional coordinate system based on the geometric arrangement of the spheres, allowing the exact tumor position to be reliably relocated — even in later sessions. This significantly reduces the need for high-radiation diagnostic steps and lowers the overall burden on patients.
