A user interface for visualizing concepts in magnetic resonance imaging

The approach, design, and implementations for CONTRAST, a user interface that visualizes concepts in magnetic resonance imaging (MRI), are described. An introduction to medical MRI is given, along with the approach to building the CONTRAST expert system. The domain-specific visual representations used in the CONTRAST user interface are discussed, as are overall interface architecture, the use of the interface for explanation, and an associated tutorial program. Some comments on building high-bandwidth user interfaces are included.<
