QA StereoChecker

Filmless CyberKnife^® QA System

Easy Method, Better Practice

Designed to be used by both physicists and therapists, this easy method for complete daily CyberKnife QA enables improved frequency and depth of QA practices, potentially improving clinical results.

Filmless and Fast

No film needed. Achieve accurate results within 0.1 mm in less time - hours reduced to minutes - while saving money and potentially increasing patient safety.

QA is done using the clinical pathway rather than the typical QA service mode for more realistic and faster results.
