This section defines the DICOM Media Storage Model used by DICOM Application Entities for the purpose of communication through the interchange of removable storage media. Specifically, this Section provides a model to clarify a number of concepts for digital imaging and communications and introduces key terms used throughout the DICOM Standard. This model has been used to partition the DICOM Standard into separate parts related to storage media interchange.
Figure 5-1 in PS3.1 presents the general communication model of the DICOM Standard, which spans both network (on-line) and media interchange (off-line) communication. Application Entities may utilize any of the following transport mechanisms:
-
the DICOM Message Service and Upper Layer Service, which provides independence from specific physical networking communication support and protocols such as TCP/IP,
-
the DICOM Web Service API and HTTP Service, which allows use of common hypertext and associated protocols for transport of DICOM services,
-
the Basic DICOM File Service, which provides access to Storage Media independently from specific physical media storage formats and file structures, or
-
DICOM Real-Time Communication, which provides real-time transport of DICOM metadata based on SMPTE and RTP.
PS3.10 describes the Basic DICOM File Service, as depicted in Figure 6.1-1.
