@neurIST (Integrated Biomedical Informatics for the Management of Cerebral Aneurysms) is an IST-FP6 European project that focuses on the management and processing of the data associated with cerebral aneurysm and its symptoms. Its major challenge is the heterogeneous nature of the input data sources since they vary in form, in context, and in nature. The new IT infrastructure that will support this must develop vertical integration across data structures and scales, and horizontal integration across data abstraction, access, processing, representation, structuring, etc. GridSystems is eager to participate in such a large-scale project that focuses on integrating and consolidating spread expertise and data, which is like taking a step further what we already do with computing resources.
