Two-in-One Solution for Patient Dose Analysis


COMPASS, the first and most sophisticated solution for advanced IMRT and rotational plan verification, provides a two-in-one solution:

  • Calculation based: Full 3D independent secondary TPS verification
  • Measurement based

COMPASS offers full workflow flexibility, allowing you to choose the most efficient workflow for any clinical need.

Key Benefits - Minimise Errors

  • Overcome the phantom uncertainties with independent secondary TPS calculation in 3D and 4D measurement based verification
  • Verify the patient plan based on a complete understanding of the clinical relevance of dose discrepancies and necessary corrective action via an independent dose engine.
  • High Accuracy: Collapsed Cone dose calculation accuracy in collaboration with RaySearch Laboratories.

Maximise Efficiency - Save Time

  • Fast and convenient access to your QA data: Patient file management flexibility with SQL 2008 database structure. Client/Server installation or stand alone SQL Express.
  • Save Time: No hybrid TPS plan required
  • Immediate "FAIL" alert if prescription doses are missed
  • Automatic PTV & OAR analysis based on your clinical protocol
  • COMPASS' CT based calculation provides the accurate dose and DVH for clinically relevant verification.


Patient anatomy based verification with RTPS accuracy!Accuracy counts! Modern treatment planning systems use advanced dose algorithms. Why would a clinician rely on a rudimentary dose algorithm for plan verification? COMPASS provides highest RTPS class accuracy dose calculation on CT and DVH that allow you to make safety critical decisions.
