PACS and RIS: approaches to integration

PACS and RIS have traditionally been discrete information systems with separate databases. Maintaining more than one database containing identical data sets creates the potential for outdated information being used in parallel with accurate information. Today, because of increased implementation of PACS and improved Web technology, this problem must be solved. Furthermore, as PACS technology is applied to areas outside radiology such database issues become more critical. Application of XML offers a cost-effective and workable solution to many of the thorniest problems that will likely become more prevalent in the post-Y2K era.
