This type of migration takes the non-DICOM supplemental objects (scanned documents, attached .JPGs, .TIF, .TXT, .DOC, PDFs) directly from the source storage and its then DICOM encapsulated using a database extract from the source system to identify all the required demographics pertaining to each object. Usually these objects become part of the “already-migrated” studies.
Data can become “stale” after time, ex: patient names changed, married, missing medical record numbers, misspelled corrections etc. This can be addressed by data extracts from the source PACS and or HL7 feed from the RIS providing ADT updates which would trigger automatic corrections as the data is migrated. Rules can be applied to prepend/append medical record numbers as required by the customer. DICOM tags can be updated to meet certain conditions to drive PACS workflow based on requirements.
