  Grid-based technologies are emerging as a potential open-source
standards-based solution for managing and collabo-rating distributed resources.
In view of these new computing solutions, the Mammogrid project is developing a
service-based and Grid-aware application which manages a Euro-pean-wide
database of mammograms. Medical conditions such as breast cancer, and
mammograms as images, are ex-tremely complex with many dimensions of
variability across the population. An effective solution for the management of
disparate mammogram data sources is a federation of autonomous multi-centre
sites which transcends national boundaries. The Mammogrid solution utilizes the
Grid tech-nologies to integrate geographically distributed data sets. The
Mammogrid application will explore the potential of the Grid to support
effective co-working among radiologists through-out the EU. This paper outlines
the Mammogrid service-based approach in managing a federation of grid-connected
mam-mography databases.
