Daily QA Trend Analyzer
Daily QA Trend Analyzer
Multi-session trend analysis of the raw data export from a daily QA ion-chamber array. Computes output, symmetry, flatness and energy per session, grades against your saved baselines + tolerances, and plots Levey-Jennings charts and a per-beam dashboard.
Upload one or more multi-session data exports from your daily QA
ion-chamber array (tab-delimited
.txt files, one per beam
energy). The analyzer reads every session in the date range,
re-computes output / symmetry / flatness / energy from the raw
detector counts, grades each beam against your saved baselines, and
renders Levey-Jennings trend charts plus a per-machine dashboard.
The corrections applied here (temperature / pressure, per-channel
offset, background, calibration factor) follow standard ion-chamber
methodology. Vendor-specific corrections are NOT replicated and
results may differ from the device's own QA software at the third
decimal. Treat the verdicts as a screening aid; the device's own
software remains the system of record for clinical sign-off.
