A DICOM device can have the role of a SCU or SCP, much like any two people engaged in conversation; both can be speakers and listeners. A device can act in different roles.

What is Storescu?

To search the PACS we use the DICOM command C-FIND. This command takes as an argument a DICOM object that represent a query. The PACS transforms the object that we send to a query, probably to SQL, runs it and then transform every result record back into a DICOM object and send it back to us in a C-FIND response.

How does the storescp application work?

The storescp application implements a Service Class Provider (SCP) for the Storage Service Class.

Received images will normally be stored in files (within the current working directory).

What transfer syntaxes are supported by storescp?

The storescp application will accept presentation contexts for all of the abovementioned supported SOP Classes using any of the transfer syntaxes: LittleEndianImplicitTransferSyntax 1.2.840.10008.1.2 LittleEndianExplicitTransferSyntax 1.2.840.10008.1.2.1 BigEndianExplicitTransferSyntax 1.2.840.10008.1.2.2

How do I enable extended negotiation in storescp?

The storescp application does not support extended negotiation. When compiled on Unix platforms with TCP wrapper support, host-based access control can be enabled with the –access-control command line option. In this case the access control rules defined in the system’s host access control tables for storescp are enforced.
