Conclusion: RESIS-ITS demonstrates high reliability in detecting discrepancies during couch rotations in LINACs, showing strong agreement with Dose-Lab with one advantage: it is a sharing home-made software. We recommend that RESIS-ITS should be incorporated into routine QA tracking tests for couch rotation verification prior RTT using couch rotation.
