Clinical Validation

“This technique is just as precise as using a traditional mask, but it significantly increases patient comfort. For many patients, it is a big relief not to have to wear a face mask during treatment.”
— Marion Essers, Medical Physicist, Instituut Verbeeten

“The DSPS-Prominent® with Vision RT® provides a safe and effective alternative for patients who previously refused treatment due to mask intolerance.”
— Dr. Paul Lesueur, Centre de Radiothérapie Guillaume le Conquérant, Le Havre

“The DSPS-Prominent® posterior mask stabilizes the head, neck, and shoulders with high reproducibility, comparable to traditional full-face masks. Vision RT® technology continuously monitors patient position using surface guidance. Any movement outside pre-set thresholds is immediately detected”
