OMI – Imaging Order Message (Event O23)

This message is used in communication between the information systems involved in the fulfillment of the request directed to the imaging department, such as a Radiology Information System (RIS) and a Picture Archiving and Communication System (PACS). For the purpose of the following discussion these systems will be identified as Imaging Department Information Systems (IDIS). Information contained in the Imaging Procedure Control (IPC) segment allows multiple IDIS to share the context of Imaging Studies (collections of images acquired, processed, stored, and interpreted) in Image Management tasks.
