Digital Pathology Workflow - Image Acquisition (DPIA) is the part of a set of profiles used in the Digital Pathology workflow - this profile supports creation of images from physical specimen e.g., creation of a whole slide image from a histology slide.

Summary

The primary function of the Digital Pathology Image Acquisition workflow is to acquire a digital image from a physical asset, usually a glass slide, but possibly also a gross specimen. Recent advancements in whole slide digital imaging technologies serve to significantly alter traditional workflows within pathology laboratories. Digital imaging in pathology typically spans two primary aspects of the conventional workflow, notably the gross / macroscopic examination and the histologic / microscopic examination.

The Digital Pathology Workflow – Image Acquisition (DPIA) Profile defines workflows and messaging transactions which focus on acquisition of a digital asset from a physical asset

Benefits

Though DICOM images can be created with little accompanying metadata beyond the scanned OCRd barcode from the slide label, they are more useful if they are populated with patient and specimen identifying and descriptive metadata retrieved from the AP-LIS acting in the role of Acquisition Manager.

Details

HL-7 V2 order messages are used for the communication from the Acquisition Manager to the Acquisition Modality (slide scanner), traditional DICOM DIMSE C-STORE transactions are used to send DICOM VL Whole Slide Microscopy Image Storage SOP Instances to the Image Manager/Archive and DICOMweb transactions are used to find and retrieve images for display by the Image Display actor.

Systems Affected

  • Acquisition Manager - AP-LIS
  • Image Manger/Archive - PACS or VNA
  • Image Display - pathologist or histotechnologist viewer or workstation
