A Call for Colour Calibration
Why digital slide scanners must be correctly calibrated to yield trustworthy results
Richard Salmon discusses Colour calibration in The Pathologist.
At a Glance
- For histopathologists, it is vital to ensure that digital images of stained tissue accurately represent the original slides
- Colour calibration for whole slide imaging can verify accurate colour representation
- Calibration is a complex issue, especially given the variations between different scanners and imaging software
- A physical, slide-based device may offer a good approach to universal calibration
Many laboratories are moving into digital imaging – scanning slides, viewing them on computer monitors, and using software-based tools to assist with analysis. But there’s an understandable hesitation from some pathologists, who ask: “How can we be sure that the digital image we see is truly representative of the slide?” In particular, with histopathology’s need for accurate staining, how can practitioners be assured that nothing is being lost or inaccurately represented in the digitisation process?
