PACS – A Personal View!

PACS Is Just…..
A picture repositoryA large data storePretty thick as a computer systems goImmatureRIS/PACS not yet nuclear medicine compliantToo reliant on a still evolving Dicom standard
PACS Limitations…
Image display only
Unable to recall data to modality workstations
Nuclear medicine low priority in RIS/PACS
Local Need For…Reviewing current patients studies with oldReprocessing
New algorithms/methodologyAuditR&DPrevious processing suspect
Reprinting/image transferPatient referralLegal casesMedical meetings
What We Have…
Archived data going back to 1990 ADAC pegasys + Siemens icon file formats
On 3 different media over 3 hospital sites
What We Need …
Robust on line archive that …Stores data in proprietary file format
Able to recall proprietary files to corresponding workstation for re-analysis
Able to view stored image data independent of platform
Able to output DICOM files
The Solution…
1.6 terabyte RAID [SuSe Linux]
Pukka-J’s Dicom explorer
Benefits…
Creating a robust archiveCan always access the original proprietary fileCan rebuild Dicom database as Dicom developsImages viewable on all hospital sitesCan add proprietary file conversion if required in the future
How It Works…
Locally written scripts move the last days images to the archive every night
Raid has a directory for each siteThis could be sub divided to file platform
Pukka-j software makes a Dicom copy into a global directory
Is It Perfect???
Nearly!! Only as good as the quality of demographic data entry Hopeful this will improve with Dicom work lists ADAC Genesys acquisition bug!! Local scripts need more error alerts/checks Hospital network issues to address with PACS implementation
Is It Perfect???
Like RIS/PACS it needs hands-on management
Pukka-J’s Dicom explorerSupports all imaging modalities
Transaxial displays etc
Benefits of dealing with a small company• Incorporated our commonly used Pegasys colour tables
• Developing home reporting package
• Create generic patches
Did I Make the Right Decision?
