Paper Abstract

At the University of Arizona a research project is underway which addresses consistent color and consistent gray-scale reproduction for digital color displays used in medical image interpretation, specifically for Pathology. Now the University of Arizona can enter the field of ICC Profiling and Color Management. Of particular interest are Verification of PerfectLum Software, conformance and deviation and the maximum GSDF Error. Verification of PerfectLum Software seemed to be successful. FIT and LUM tests were performed to verify the conformance and the deviation was quantified. The maximum GSDF Error turned out to depend slightly on the bandwidth of the PR-670 Spectrophotometer. Measurements were made at two settings each of Normal and Fast. At the setting "Normal" the maximum GSDF Errors were 8.6% and 6.1 %. At the setting "Fast" the maximum GSDF Errors were 7.44 % and 5.76%. With respect to the results, all three objectives were met and the PerfectLum calibrated display was confirmed to the AAPM TG18 standards.
