With CNERGY QA hospitals can automatically execute an independent quality check with their EPID system for safety and compliance purposes (NCS24). The daily morning check measures output, symmetry and flatness to ensure that beam output is properly tuned. Image quality of the EPID system can be easily monitored with a ContrastDetail or a QC3-phantom. An accurate calibration method measures the multileaf collimator positions.³
