Hospital Environment Today
Archive
Radiology
• DICOM archive• 50MB-2GB files• First generation
obsolete• “Closed” archives• Archive dedicated
to each PACS
Archive
Cardiology
• DICOM or non-DICOM
• Little or no archiving (DVD)
• 500MB-1GB files• Dedicated archive
Storage
..ologies
• Non-DICOM• Little or no

Backup
Other Applications
• Non-DICOM• Backup and
archiving• Small to very
large files• Dedicated
storage
• Different vendors, isolated archives
• No sharing of infrastructure
• No sharing of information base
• May be located at different sites

Vendor Neutral Archive
• VNA provides centralized medical content repository
• ‘Any to any’ access (controlled)
• Ensures compliance with data privacy regulations
• Simplifies maintenance and reduces storage cost

VNA – Not just a digital dump ground
Open and standards based
Managed and structured
Leverage information
Scalable and secure

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
Indexing VNA
Objects
Meta Data
Indexing• Automated• Manage vendor specific headers• Customizable• Configurable• Rules driven
Objects• Strip to the native format• Follow open standards• JPEG, JFIF, PDF, MPEG etc• Avoid properitary formats• True vendor neutral format• Make available as non-DICOM
Meta Data• Decompose most of the header• Make as mush header
information available as possible• Don’t loose any information
stored in the DICOM header• Preserve integrity of DICOM obj

What to look for when storing in VNA. Manage cost of ownership.Manage the cost when the tsunami hits
VNA
Hirachical Storage Mgmt• Combine fast on-line with slower
and less expensive near-line
and off-line (tape) storage• Policy driven migration based
e.g. on DICOM header
information or class of
information
Other means• Compression, even most native
object formats already are
compressed
De-dublication• Automated detection and
removal of dublicates• Policy driven removal of
intermediate versions
Retention & Disposition• Rules-based event-driven
retention and disposition• Not just age of study, but e.g.
events like ”patient turns 18 yrs”• Meet regulations and at the
same time manage TCO

VNA for non-DICOM objects. Interfaces are kings.
WebDAV• Older W3C standard originated
in 1996• Based on HTTP• Support is fading
Java Cnt Repository (JCR)• J2EE standard initiated as
JSR170 in 2003• JCR 2.0 in the works from 2010
as JSR283
CMIS• Content Management
Interoperability Services• Recent (2010) OASIS standard
backed by major vendors like
Microsoft, IBM, ECM, Adobe
and others
File System Exchange• Vendor specific interfaces• Often based on file pairs of
object and XML descriptor file• Async and batch oriented• Can include parsing of e.g.
PDFs
XDS• VNA shall be XDS repository• Better more scalable security
model than native VNA• XDS-SD for scanned documents• XDS for HL7 CDA docs• XDR, XDM?
Vendor specific adaptors• Most VNA vendors provides
interfaces and API toolkits for
on-line synchronous application
integration

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