Sept 13-15, 2004Cameron – p. 8IHE Educational Workshop 2004 Transactions Modality Procedure Step In Progress An Acquisition Modality notifies the Performed Procedure Step Manager of the start of a new Procedure Step and the PPS Manager informs the Department System Scheduler/Order Filler and Image Manager. [CARD-1, derived from RAD-6]  Intermittently connected workflows may send the MPPS “In Progress” immediately preceding the MPPS “Complete”

Sept 13-15, 2004Cameron – p. 9IHE Educational Workshop 2004Transactions Modality Images/Evidence Stored – An Acquisition Modality sends acquired or generated images, waveforms, or other evidence documents to the Image Archive.

Sept 13-15, 2004Cameron – p. 13IHE Educational Workshop 2004 Transactions Storage Commitment – A requestor (Acquisition Modality) requests that the Image Manager confirm ownership for the specified DICOM objects (images, waveforms, evidence documents, or any combination thereof) that the requestor stored in the Image Archive, thus allowing the sender to delete those objects now owned by the Image Manager. [CARD-3, derived from RAD-10]  This option requires the Image Manager to send the N-Event Report message to the mobile modality at the time that reconnects to the Image Manager.
