  • Detect deviation early and ensure maximum machine uptime
  • Visual pass/fail analysis
  • myQA guides through the QA in a straightforward and efficient manner

Most Reliable

  • Unique workflow integrates all your QA needs
  • Ready for TG-224
  • Your easy solution to verify the most important beam and imaging parameters

Gain 20 minutes of QA time

  • Complete your tests in less than 10 min
  • Treat one more patient each day

Conclusion
The proposed combination of the Lynx® + Sphinx® systems appear to be suitable as a device for daily QA of proton range for PBS proton therapy, even under extreme, and very unlikely, set-up and beam delivery uncertainties.
