Paper Abstract

LCDs suffer from viewing angle dependency, meaning that characteristics of LCDs change with viewing angle. DICOM GSDF calibration and corresponding quality checks typically take place for on-axis viewing. However, users will use the display for a broad range of viewing angles. Several studies have shown that when calibration is done for on-axis viewing then the display is not accurately complying with the DICOM GSDF standard when viewing off-axis. This paper presents a novel solution: we adapt the DICOM GSDF calibration algorithm to have inherent robustness against change of viewing angle. A validation has been done by means of a 5 Mega Pixel medical display. Results show that it is possible to double the range of viewing angles (18° instead of 9°) for which the display is within the 10% tolerance as defined in the DICOM GSDF standard. This result is very useful because users typically will use their displays also for off-axis viewing angles.
