The Document Management System will provide high-volume long-term storage and management capabilities for all non-DICOM CORTISONE content. It is also expected to provide advanced document capture, version control, retention/disposal, search and flexible access control capabilities; and to be capable of managing records of content stored in non-digital form, or in another digital store. This should also include a Vendor Neutral Archive (VNA). The VNA will provide vendor-independent storage and management for DICOM standard medical images. This will be directly accessible by the legacy and future CORTISONE PACS/RIS (and other native DICOM systems) and will sit alongside, and be integrated with, the Document Management System. A Zero Footprint Viewer will also be required, to provide a high level of DICOM image display functionality from within a browser.
