Assessing color reproducibility of whole-slide imaging scanners

A new method for assessing color reproducibility of whole-slide imaging (WSI) systems is introduced. A color phantom is used to evaluate the difference between the input to and the output from a WSI system. The method consists of four components: (a) producing the color phantom, (b) establishing the truth of the color phantom, (c) retrieving the digital display data from the WSI system, and (d) calculating the color difference. The method was applied to a WSI system and used to evaluate the color characteristics with and without color management.
