Technical implementation details of a biobank portal enhanced with digital pathology features

Download to read offline

Facilitating biobanks are a novel application for digital pathology. The Brussels Free University (VUB) and its teaching hospital UZ Brussel, together with the Belgian Diabetes Registry have developed one of the world’s largest biobanks in the domain of type 1 diabetes. The digital pathology platform of Pathomation was deployed to facilitate access to the tissue collection and promote basic and clinical research. Clinical data is available side by side to whole slide image data in a seamless and transparent interface, assisting the researcher to make an optimal selection of material of interest for a particular study. Digital pathology is thus presented as a natural add-on to a biobank query interface.
