Abstract

A medical image storage and retrieval system includes a database with relationally linked tables including a disease factoid table, an image and image caption table, and a patient data table. A flexible system allows for peer review, remote access and maintenance of the stored data, and query searching and retrieval of groups of related multimedia (image and text) case file information. The system facilitates distance learning and remote consultation.
