What our customers say

The Philips IntelliSite Digital Pathology Solution has the capabilities to upload, view and annotate the images produced from the Grundium scanner. Zooming and panning is really fast, even when the images are physically stored on a server in the Netherlands and I’m viewing the images from a workstation in Sweden.
