What pacsDisplay is

pacsDisplay is free, open-source software for calibrating DICOM grayscale displays and checking their quality on Windows 10 and 11. Its tools measure a display’s luminance response and generate DICOM GSDF calibration lookup tables. The iQC program provides interactive quality-control patterns, including TG270-pQC, TG270-sQC, and TG270-ULN. For uniformity checks, uniLum gathers luminance measurements and reports deviation from the median and mean luminance deviation. Other tools evaluate ambient lighting and measure luminance and illuminance.

The project lists several compatible photometers, including X-Rite i1Display models, NEC SpectraSensor Pro, ColorMunki Display, Calibrite Display models, and rebranded meters. Version 6A supports external-display measurements in lumResponse and uniLum. Its pdQC toolkit can be deployed from a USB drive or network without installation. The Windows installer places files in Program Files, the Public Users folder, and the Start Menu without changing the registry or system services. Development began in 1999. pacsDisplay is licensed under GNU GPL v3.0; bugs can be reported through GitHub Issues or by email to nick 'at' pacsdisplay.org.

Good

  • Generates DICOM GSDF calibration LUTs.
  • Includes interactive quality-control patterns.
  • Reports luminance uniformity deviations.
  • pdQC can run without installation.

Watch out

  • The current release supports Windows 10 and 11.
  • Some measurement functions require a compatible photometer.

Who it suits

pacsDisplay suits people responsible for calibrating DICOM grayscale displays and checking display quality in Windows 10 or 11 environments. It is also relevant to users with one of the listed compatible photometers.

Verdict

pacsDisplay combines grayscale calibration, quality-control patterns, and luminance measurements for Windows. Check its supported Windows versions and photometer compatibility before using it in a workflow.
