The Semperdata™ Difference

Semperdata is unique in its fusion of data migration and storage technologies. It incorporates:

  • The industry-leading migration engine used in Laitek’s Migratek® data migration services
  • A secure journaling archive system storing DICOM standard files plus documented change-tracking objects
  • Optional connections to legacy archives providing full DICOM access to legacy images and annotation

KEY DIFFERENTIATORS

In addition to the DICOM storage, query and retrieval of conventional archives, Semperdata™ has the following distinguishing features:

  • Migration capability– Whether you use Semperdata as transitional storage or for long term archiving, the ultimate measure of data permanence is the ability to migrate to a successor system. The Semperdata archive includes the Migratek® Migration Controller, which features
    • Flexible user interface that allows you to define multiple migration streams, conditioned on modality, date range, source, RIS-PACS matching rule number & status, and other study status attributes.
    • Validation. Compare source and destination image counts for migrated studies.
    • Verification. Compare source and destination metadata and pixels for migrated studies.
    • Speed. Multiple streams and time of day / day of week bandwidth shaping for highest sustained transfer rates.
  • Remapping & Transformation – Reversible and auditable changes can be applied to archived data by Operator editing tools, and Rule-base RIS-PACS matching (in conjunction with data migration services).
  • Media-standard Storage– The complete content of a Semperdata archive can be recovered from the archive media alone, even in the absence of the Semperdata archive server that wrote the media. Storage in DICOM Part 10 files is not enough to allow full recovery, because archives record changes to patient demographics and other metadata in their databases.
    • The Semperdata system writes all updates into “Change Objects” stored with the image data. Semperdata software can completely rebuild an archive from the stored objects.
    • The DICOM Standard does not presently include such Change Objects, and thus Semperdata implements them as DICOM private objects documented in the Semperdata DICOM conformance statement.
  • Legacy Storage Connectors– Semperdata can seamlessly integrate with many legacy archives, providing direct DICOM access to legacy data still in its original file storage systems.
    • Available for most legacy archives
    • Access proprietary annotation as DICOM Grayscale Softcopy Presentation State objects.
    • Embed annotation in image objects for DICOM clients that do not support GSPS.

BENEFITS

key differentiatorsbenefits
media-defined storageThe complete content of a Semperdata archive can be recovered from the archive media alone, even in the absence of the Semperdata system that wrote the media
  • Practical and secure journaling storage, enables low cost disaster recovery readiness
  • All updates into “Change Objects” stored with the image data
  • Protection from loss of LAITEK as a support resource
  • Information consistency markers stored with the data; customer fully owns the data and does not depend on LAITEK database schemas
legacy storage connectorsSecure storage that still delivers accessibility is key.
  • Seamless integration with legacy archives, providing direct DICOM access to legacy data still in its original storage systems
  • Access proprietary annotations as DICOM Grayscale Softcopy Presentation State objects or Group 6000 as required
migration capabilityWhether you use Semperdata as transitional storage or for long term archiving, the ultimate measure of data permanence is the ability to migrate to a successor system.
  • Combination of migration with storage capabilities allows early retrieval from legacy archives, in advance of new PACS installation
  • Fastest retrieval of legacy data on the market
  • Outbound migration with the full power of Migratek Advanced Data Migration
remapping and transformationReversible and auditable changes can be applied to archived data.
  • Rules-based RIS-PACS reconciliation with data migration services
  • Manual editing with full reversibility
