See Section 5 for diagram.3.2.10 SCUa Service Class User (SCU) is a device thatinitiates DICONDE requests from an SCP.

22、SCU types mostcommonly include the storage type (C-STORE or C-MOVE) toallow sending of data to another device for storage and the findtype (C-FIND) to enable searching and retrieval of stored data.A device may serve as both SCU and SCP.

Summary of Prac

24、tice4.1 This practice is intended for use by NDE systemmanufacturers and NDE system purchasers, who need to assessthe technical extent of a systems compliance and conformanceto the DICONDE standard. The procedure is organized in sucha way that the level to which the DICONDE standard issupported is e

25、vident by the last step of the procedure thatpasses. The intent is for a vendor to be able to verifyDICONDE compliance internally and validate DICONDEcompliance with an external system without participating in aconnect-a-thon. It provides concrete examples for how toachieve this without mandating a

26、specific means for verifica-tion and validation. It achieves this by keeping the procedureabstracted from an implementation, and placing an exampleimplementation suggestion in Appendix X1.4.2 The practice is intended to verify and validate all theApplication Entities of interest to the user for the

For example, a system under evaluation for DICONDEnetworking interoperability may have more than one Applica-tion Entity: One may be dedicated to responding to searchrequests, and another may be dedicated to receiving imageda

Significance and Use5.1 This practice describes the recommended procedure forNDE system manufacturers and NDE system purchasers toassess the systems level of compliance and conformance to theDICONDE standard.5.2 The use cases for interconnectivity and interoperabilityare illustrated in Fig. 1.
