Imorgon Server DICOM Conformance Summary (Imorgon 2.0)

For information on modality specific configurations, please see this page

Functional Summary

SOP Class Name Functional Description
Ultrasound Multi-frame Image Storage Stores images to the Imorgon Server. Sends images to another AE like PACS archive.
Ultrasound Multi-frame Image Storage (Retired) Stores images to the Imorgon Server. Sends images to another AE like PACS archive.
Ultrasound Image Storage Stores images to the Imorgon Server. Sends images to another AE like PACS archive.
Ultrasound Image Storage (Retired) Stores images to the Imorgon Server. Sends images to another AE like PACS archive.
Secondary Capture Image Storage Stores images to the Imorgon Server. Sends images to another AE like PACS archive.
Verification SOP Class Responds to "DICOM ECHO" commands from external AEs, requests DICOM ECHO to other AEs.
Modality Worklist Information Model - FIND Retrieves patient demographics and schedule information.
Modality Performed Procedure Step SOP Class Receives study status updates such as begin, end or discontinuation of a modality study.
Storage Commitment Push Model SOP Class Used only to receive the signal "end of study" condition from ACUSON Sequoia scanners only. MPPS should be used whenever possible.
Study Root Query/Retrieve Information Model – FIND Queries central PACS archives to retrieve prior studies.
Study Root Query/Retrieve Information Model – MOVE Retrieves prior studies from a central PACS archives.
Enhanced Structured Report StorageReceives Ultrasound Calculation and Bone Mineral Density (DEXA) Package reports for display and transmission to dictation or reporting system of numerical results.
Comprehensive Structured Report Storage Receives Ultrasound Calculation Package reports for display and transmission to dictation or reporting system of numerical results.
Encapsulated PDF StorageStores or generates PDF documents.
ACUSON Proprietary Structured Report StorageReceives Ultrasound Calculation Package reports for display and transmission to dictation or reporting system of numerical results generated by Siemens/ACUSON Sequoia systems.
Key Object Selection Document Storage Receives the list of valid and invalid images acquired in order to remove invalid images from the Imorgon server and prevent those from being sent subsequently to the PACS archives.
NOTE: Imorgon Server may coerce Patient Name, Patient ID, Accession Number, DOB or Sex fields of images to match the "system of records" values when it is operating as a storage class service user. The changes will be based on the Modality Worklist or the HL7 Order Change messages.
