As the volume of digital medical images grows, and the access requirements increase, the traditional centralized approaches to image communication, storage and archiving are becoming increasingly expensive to scale and operate with high levels of reliability. New approaches are needed to address fault tolerance, scalability and multi-site geographically distributed deployments with limited bandwidth connectivity.

This seminar presents a clinical deployment of a multi-site image distribution network developed using a new architecture for data communication and storage. This approach utilizes a distributed network of low cost, off the shelf servers (nodes) that together form a computing and storage grid that provides data and metadata storage, processing and communication without single points of failure. Imaging studies are transparently stored, replicated, cached and managed based on pre-defined business rules, and all nodes within the network can capture studies and respond to queries. Nodes transparently load balance requests and replicate data for automated backup and recovery. Scaling the system involves adding new nodes, and the failure of nodes does not result in lost or inaccessible data.

This approach increases reliability and availability, provides near-linear scalability and allows the creation of a geographically distributed medical imaging network infrastructure.

Moe Kermani is president and CEO of Bycast Inc. He holds a PhD in physics from the University of British Columbia. Before joining Bycast, Dr. Kermani was the chief scientist and director of research and development for Sonigistix Corporation, a world leader in the field of high performance audio systems. He has been awarded several US patents for his work at Sonigistix. Prior to that Dr. Kermani was involved in physics research at the TRIUMF Nuclear Physics Research Laboratory.
