Various translations:

Association Connection between two programs DICOM by which information DICOM is exchanged. A given machine can manage one or more associations simultaneously
Attributes trad: attributes

Elements describing caratéristique of an object, a flow DICOM exchanges primarily attributes specific to the objects transmits, each attribute has a value.
Byte order Command of the bytes: way of assembling them to form an entirety of two bytes or more:
Little endian : value of the entirety octet1*256 +octet2 = the least significant byte in the last
Big endian : value of the entirety: octet2*256 +octet 1 = the most significant byte in the last
Composite objects trad: objects composite S.

Objects décrivants several types of attributes DICOM, the images are composite objects, is opposed to a standardized object.
Dated Dictionnary Data dictionary.
Dated set Trad: data file

Together of data in which each attribute DICOM has an eigenvalue corresponding to a real object (an image for example).
Dated Element Element of data, data element of " Dated Set ", width example of an image.
Information objects Dicom objects whose function is to convey precise information, object whose descriptive attributes are indexed and defined in the standard.
Information object authority A precise object, whose attributes DICOM all are assigned and correspondent with a single entity of a class of data, a instance.(exemple: the report of Mr. Dupont)
Normalized objects trad: standardized object

Objects defining only one entity DICOM having only one attribute. Be opposed to a composite object which describes several attributes.
Analyze Orientée Object Together of information and specific functions connected to each other in a virtual way. A given object can inherit the functions and information another object (example: the object " Image IRM " inherits the functions and information the class of " the Images ").

Certain information and functions of an object are not " visible " outside this object (encapsulation), which makes it possible to create programs by associated and interchangeable modules.

In practice, at the physical level, an object is a whole of successive bytes occupying a certain quantity of place in memory.
Offset Initial jump, a number of bytes to be jumped before starting to read information or a table.
Protocol Together of rules allowing two machines to communicate. DICOM describes a whole of rules making it possible the applications to communicate, these rules suppose that connect them physical and the communications protocols between two machines were solved.

Protocol DICOM intervenes only at the time of the communication of a program with another, it supposes connected them of low level carried out.
Tag Trad: Limit or a beacon , in DICOM the name in a numerical form of an attribute. (example the beacon corresponding to the width of the image is: 0028 0010 H)
Transfer syntax Trad:Syntaxe of transfer

Description in the way in which is transmitted the VR(Value Representation) of information: the command of the bytes (byte order) and possibly the type of compression
Been worth representation (VR)

Mode of representation of the value (binary, text, alphanumeric...)

Not to confuse:

  • Byte Order (little or Big endian)
  • Transfer Syntax(Order Byte + possible compression)
  • Been worth Representation(texte, binary, whole, real...)
