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

archiving• Small files• Dedicated

storage

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

Hospital Environment Tomorrow


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

DICOMHeader


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


Complexity from the many choices

• Driving business innovation

• Make new markets• Respond to competitive

threats• Enhance the customer

experience
