pacsDisplay
pacsDisplay is an open-source project for calibrating DICOM grayscale displays and checking their image quality. Its calibration tools measure luminance response and create DICOM GSDF lookup tables. The iQC tool shows interactive quality-control patterns, including TG270-pQC, TG270-sQC, and TG270-ULN. For uniformity checks, uniLum collects luminance measurements and reports deviation from the median and mean luminance deviation. Other tools assess ambient lighting and measure luminance and illuminance. The listed compatible photometers include X-Rite i1Display Studio, Pro, and Plus; NEC SpectraSensor Pro; ColorMunki Display; Calibrite Display Pro and Plus HL; and rebranded meters. Version 6A supports external-display measurements in lumResponse and uniLum. The current release supports Windows 10 and 11. 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 modifying the registry or system services. Development began in 1999, and the project is distributed under the GNU General Public License v3.0.
