Why top treatment centers choose 

the SDX® System by DYN'R

Reproducible positioning is the key to successful radiation treatment.

Though camera systems are easy to use, their main strength is patient positioning prior to treatment. But to what extent is the movement of the thorax a true reflection of what’s happening internally?


SDX® uses a direct measurement of lung volume, giving therapists  real-time internal information that enhances precision for all thoracic-abdominal cancer treatments.  SDX® spirometer and video goggles increase patient confidence and mastery of DIBH technique with 95% success.


Ensure your patients are benefitting from the best technique to target tumors while protecting nearby tissue.
