  1. 1. Peter B. LangeExecutive IT-ArchitectOffice of the CTO, Public Sector, IBM EuropeVNA for indexing & storing DICOM & non-DICOM objects- A point-of-view from a CTOUK Imaging Informatics Group – Birmingham November 6, 2012 © 2012 IBM Corporation

Hospital Environment Today Tomorrow Radiology Cardiology ..ologies Other Applications Vendor Neutral Archive Archive Archive Storage Backup • DICOM archive • DICOM or non- • Non-DICOM • Non-DICOM • 50MB-2GB files DICOM • Backup and • Little or no • First generation • Little or no archiving archiving obsolete archiving (DVD) • Small to very • Small files • “Closed” archives • 500MB-1GB files large files • Dedicated • Archive dedicated • Dedicated archive storage • Dedicated to each PACS storage ••VNADifferent vendors, isolatedmedical content repository • provides centralized archives • VNA provides centralized medical content repository Different vendors, isolated archives •• ‘Anytotoany’ access (controlled) • ‘AnyNo sharing of infrastructure • No sharing of infrastructure any’ access (controlled) •• Ensures compliance with sites privacy regulations • • No sharing of information base • Ensuressharing of information baseprivacy regulations No compliance with data May be located at different data •• Simplifies maintenance and reduces storage cost • Simplifies maintenance and sites May be located at different reduces storage cost © 2012 IBM Corporation2

  4. 4. What to look for when indexing in VNA. Become and stay vendor neutral.Avoid VNA vendor lock-in, unlock DICOM content and secure future interoperability Objects DICOM Indexing Header VNA Meta DataIndexing Objects Meta Data• Automated • Strip to the native format • Decompose most of the header• Manage vendor specific headers • Follow open standards • Make as mush header• Customizable • JPEG, JFIF, PDF, MPEG etc information available as possible• Configurable • Avoid properitary formats • Don’t loose any information• Rules driven • True vendor neutral format stored in the DICOM header • Make available as non-DICOM • Preserve integrity of DICOM obj © 2012 IBM Corporation4
  5. 5. What to look for when storing in VNA. Manage cost of ownership.Manage the cost when the tsunami hits Hirachical Storage Mgmt De-dublication • Combine fast on-line with slower • Automated detection and and less expensive near-line removal of dublicates and off-line (tape) storage • Policy driven removal of • Policy driven migration based intermediate versions e.g. on DICOM header information or class of information Other means Retention & Disposition • Compression, even most native • Rules-based event-driven object formats already are retention and disposition compressed • Not just age of study, but e.g. events like ”patient turns 18 yrs” • Meet regulations and at the same time manage TCO VNA © 2012 IBM Corporation5
  6. 6. VNA for non-DICOM objects. Interfaces are kings. WebDAV Java Cnt Repository (JCR) CMIS • Older W3C standard originated • J2EE standard initiated as • Content Management in 1996 JSR170 in 2003 Interoperability Services • Based on HTTP • JCR 2.0 in the works from 2010 • Recent (2010) OASIS standard • Support is fading as JSR283 backed by major vendors like Microsoft, IBM, ECM, Adobe and others File System Exchange XDS Vendor specific adaptors • Vendor specific interfaces • VNA shall be XDS repository • Most VNA vendors provides • Often based on file pairs of • Better more scalable security interfaces and API toolkits for object and XML descriptor file model than native VNA on-line synchronous application • Async and batch oriented • XDS-SD for scanned documents integration • Can include parsing of e.g. • XDS for HL7 CDA docs PDFs • XDR, XDM? © 2012 IBM Corporation6

RIS/PACS Server Platform • Support a broad set of • CPU RIS/PACS and other diagnostic • 32/64 bit imaging systems • Multi-core • Easy configuration and • Form factor customization of interface Software Platform Storage Platform • Operating System • Tiered storage • Database • Network attached storage • Application server • Identity management • Systems management • Reporting VNA © 2012 IBM Corporation7
