- DIN 6868-157:2022-01 fully covered — acceptance testing (§8) incl. 9-point homogeneity, half-yearly + daily constancy (§10), classification per Tables 6/7, automatic 20-/30-% rule evaluation
- Pixel-exact test patterns — TG18-UN10/UN80, TG18-MP, 18-point TG18-LN8 patches, TG18-LPH/LPV line gratings rendered at runtime on the display's native resolution; anatomical patterns (TG18-QC/CT/AD) from the AAPM archive
- Multi-monitor workflow — automatic detection of all attached displays, single-monitor protection with overlay flow, click-through wizard per display device
- PAdES-signed test reports — Annex C.1/C.2/C.3 form layouts as native PDF, one RSA-2048 certificate per qualified tester (issued by the EVIQUS portal), optional PAdES-T with RFC 3161 timestamp (FreeTSA / DigiCert / GlobalSign)
- Half-yearly constancy with baseline tracking — automatic comparison against the last acceptance / baseline run, 18-point characteristic curve only triggered when Table 9 requires it
- Cross-platform — Windows 10/11 and macOS 12+ (Avalonia 12 / .NET 10), one codebase, identical workflow
- Portal integration — outbound sync queue with exponential backoff, login backfill, signed-PDF upload, audit trail via EVIQUS portal
- Offline-capable — tests run locally with a SQLite outbox; portal sync and update checks happen in the background once an internet connection is available
- Daily reminder + tray mode — app starts minimised to the system tray and brings the main window forward when a daily constancy test is due
- DIN-cited report labels — all limit values, measurement points and pass/fail wording are cited from DIN 6868-157:2022-01 (Tables 3–9 and Annex C)
- Integrated feedback and automatic crash reporting — tickets route directly into the EVIQUS support project MQA-FEEDBACK with sanitized log attachments

System Requirements — EVIQUS MonitorQA
Workstation (minimum)
- Windows 10 20H2 or higher / Windows 11
- macOS 12 (Monterey) or higher
- 4 GB RAM (8 GB recommended for multi-monitor setups)
- 2 GB free disk space (app + test-pattern cache + local SQLite outbox)
- CPU: any x64 processor with .NET 10 support (Intel / AMD / Apple Silicon)
Displays
- At least one reading or mammography monitor under test
- Recommended: a separate console display for running the wizard (single-monitor setups are supported via an overlay flow — not a blocker)
Photometer (for full acceptance / constancy testing)
- Any DIN 6868-157-compatible luxmeter / luminance meter (values are entered manually — no proprietary driver required)
Network
- Internet optional — used only for portal sync, auto-update, qualified-tester certificate retrieval and crash reporting
- Tests themselves run fully offline; reports are stored locally
under
~/Documents/EVIQUS Monitor-QA/
EVIQUS portal (optional, recommended)
- Account on
portal.eviqus.com(provisioned at first install) - Customer site is selected once in settings (1 installation = 1 customer site)
Tech-Preview notice
EVIQUS MonitorQA has been running in production with active portal
integration for pilot practices since May 2026. The desktop app is
currently on the beta update channel; the macOS variant (mqa_osx)
is built but not yet released to pilot sites. Auto-update for
macOS will follow once the cross-platform EVIQUS.UpdateClient v2.3
ships (roadmap: summer 2026).
04 Description
Cross-platform quality-assurance software for DIN 6868-157 acceptance and constancy testing of medical display devices. Pixel-exact test patterns, qualified-tester-signed PDF reports, portal integration. Beta available.
