3.8 DICOM Media Storage and File Format Definitions​

The following definitions are commonly used in this Part of the Standard:​

Application Profile​

A Media Storage Application Profile defines a selection of choices at the various layers of the​

 

DICOM Media Storage Model that are applicable to a specific need or context in which the media​

 

interchange is intended to be performed.​

DICOM File Service​

The DICOM File Service specifies a minimum abstract view of files to be provided by the Media​

 

Format Layer. Constraining access to the content of files by the Application Entities through such​

 

a DICOM File Service boundary ensures Media Format and Physical Media independence.​

DICOM File​

A DICOM File is a File with a content formatted according to the requirements of this Part of the​

 

DICOM Standard. In particular such files shall contain, the File Meta Information and a properly​

 

formatted Data Set.​

DICOMDIR File​

A unique and mandatory DICOM File within a File-set that contains the Media Storage Directory​

 

SOP Class. This File is given a single component File ID, DICOMDIR.​

File​

A File is an ordered string of zero or more bytes, where the first byte is at the beginning of the​

 

file and the last byte at the end of the File. Files are identified by a unique File ID and may by​

 

written, read and/or deleted.​

File ID​

Files are identified by a File ID that is unique within the context of the File-set they belong to. A​

 

set of ordered File ID Components (up to a maximum of eight) forms a File ID.​

File ID Component​

A string of one to eight characters of a defined character set.​

File Meta Information​

The File Meta Information includes identifying information on the encapsulated Data Set. It is a​

 

mandatory header at the beginning of every DICOM File.​

 

File-set​

A File-set is a collection of DICOM Files (and possibly non-DICOM Files) that share a common​

 

naming space within which File IDs are unique.​

 

File-set Creator​

AnApplicationEntitythatcreatestheDICOMDIRFile(seeSection8.6)andzeroormoreDICOM​

 

Files.​

 

File-set Reader​

An Application Entity that accesses one or more files in a File-set.​

 

File-set Updater​

An Application Entity that accesses Files, creates additional Files, or deletes existing Files in a​

 

File-set. A File-set Updater makes the appropriate alterations to the DICOMDIR file reflecting the​

 

additions or deletions.​

 

DICOM File Format​

The DICOM File Format provides a means to encapsulate in a File the Data Set representing a​

 

SOP Instance related to a DICOM Information Object.​

 

Media Format​

Data structures and associated policies that organize the bit streams defined by the Physical​

 

Media format into data file structures and associated file directories.​

 

Media Storage Model​

The DICOM Media Storage Model pertains to the data structures used at different layers to​

 

achieve interoperability through media interchange.​

 

Media Storage Services​

DICOM Media Storage Services define a set of operations with media that facilitate storage to​

 

and retrieval from the media of DICOM SOP Instances.​

 

Physical Media​

A piece of material with recording capabilities for streams of bits. Characteristics of a Physical​

 

Mediaincludeformfactor,mechanicalcharacteristics,recordingpropertiesandrulesforrecording​

 

and organizing bit streams in accessible structures​

 

Secure DICOM File​

ADICOMFilethatisencapsulatedwiththeCryptographicMessageSyntaxspecifiedinRFC2630.​

Secure File-set​

A File-set in which all DICOM Files are Secure DICOM Files.​

 

Secure Media Storage​

A DICOM Media Storage Application Profile that requires a Secure File-set.​
