Machine QA


The Machine QA option coupled with the advanced Delta4 data acquisition system allows users to perform periodic QA of the therapy machine. Delta4 brings a new dimension into machine QA.

With measurements of each individual dose pulse, you can now analyze start-up sequences and reproducibility and analyze beam parameters versus time or monitor units.

Machine QA is no longer restricted to only the upright gantry angle. With Delta4 Machine QA, it can be performed in various gantry angles.

Delta4 Machine QA allows:

  • Advanded machine QA done in few minutes
  • Stability check with high accuracy and detailed analysis
  • Beam constancy at various gantry angles
  • MLC performance check at various gantry angles
  • Film-free picked fence test
  • Discover and track long-term effects and trends
