What is SOP Class UID?
Each DICOM standard SOP Class is identified with a Unique Identifier (UID). These SOP Class UIDs are issued by NEMA so that they can be used by the software that performs the actual negotiation, as well as to specify which SOP class it represents.
What does SOP stand for Dicom?
A Service-Object Pair (SOP) Class is defined by the union of an Information Object Definition (IOD) and a DICOM Service Elements (DIMSE). The SOP Class definition contains the rules and semantics which may restrict the use of the services in the DIMSE Service Group or the Attributes of the IOD.
What is SCU and SCP in DICOM?
DICOM is based on two-way communication, which means that there is always one device that sends and one that receives. Or in DICOM terminology, one device that invokes an operation and the other one that performs it. In DICOM these roles are called Service Class User (SCU) and Service Class Provider (SCP).
What is IOD in DICOM?
An Information Object Definition (IOD) is an object-oriented abstract data model used to specify information about Real-World Objects. An IOD provides communicating Application Entities with a common view of the information to be exchanged.

PDUs are constructed by mandatory fixed fields followed by optional variable fields that contain one or more items and/or sub-items.
What is Dimse?
The DICOM Message Service Element (DIMSE) provides the mechanism for message exchange between peer Application Entities once an Association between them has been established.

What is the difference between PACS and DICOM?

What are the two types of PDUs used at the network layer?
Protocol data units for the Internet protocol suite are: The transport layer PDU is the TCP segment for TCP, and the datagram for UDP. The Internet layer PDU is the packet.
What is RIS and CIS?
A RIS or Radiology Information System is software that your staff can use to keep better track of each patient being treated.
