Web-based pathology annotation

In the HPA program, the objective has been that all immunohistochemistry images should be manually annotated by a certified pathologist. A web-based annotation tool was developed taking advantage that all tissue images was scanned to generate high resolution digital images. A “annotation jamboree” was organized in which a large number of Scandinavian pathologists came together and performed annotation of hundreds of thousands of pathology images. However, due to the increased throughput of images, a new strategy to keep up with the production of images was necessary. A dedicated site with pathologists was set-up in Mumbai, India headed by Dr Sanjay Navani. This HPA affiliated site have now annotated more than 10 million images published on the open access resource (Human Protein Atlas).
