Performed Procedure Protocol SOP Instance(s) that describe the conditions by which this Instance was generated.
Required if a related Performed Procedure Protocol SOP Instance was created.
One or more Items shall be included in this Sequence.
See Section 10.41.1.

10.41.1 General Procedure Protocol Reference
The Referenced Defined Protocol Sequence (0018,990C) contains a reference to the Defined Procedure Protocol SOP Instance(s) and protocol element that were used to generate this Instance. The Referenced Performed Protocol Sequence (0018,990D) contains a reference to the Performed Procedure Protocol SOP Instance(s) and protocol element that describe the conditions by which this Instance was generated.
Multiple Items in the Referenced Defined Protocol Sequence (0018,990C) may represent a group case where several Defined Procedure Protocols were performed together as a single Performed Procedure Protocol.
Multiple Items in the Referenced Performed Protocol Sequence (0018,990D) are recommended if the acquisition and reconstruction were recorded in separate Performed Procedure Protocol SOP Instances. However, it is not intended that this Sequence references Defined or prior Performed Protocol SOP Instances on which the current Performed Procedure Protocol SOP Instance was based. Such references may be found inside the current Performed Procedure Protocol SOP Instance itself.
In case where the acquisition and the reconstruction are done in two separate devices connected through the network, the reconstruction device can use the Source Acquisition Protocol Element of the Referenced Defined Protocol to determine the images that will be reconstructed with a given reconstruction protocol element.
