7 DICOM Model of the Real World

Figure 7-1a, Figure 7-1b and Figure 7-3 depict the DICOM view of the Real-World that identifies the relevant Real-World Objects and their relationships within the scope of the DICOM Standard. It provides a common framework to ensure consistency between the various Information Objects defined by the DICOM Standard.

7.1 DICOM Information Model

The DICOM Information Model is derived from the DICOM Model of the Real World. The DICOM Information Model presented by Figure 7-2b, Figure 7-2c and Figure 7-2d identify the various IODs specified by this Standard and their relationships. There is not always a one-to-one correspondence between DICOM Information Object Definitions and Real-World Objects. For example a Composite IOD contains Attributes of multiple real-world objects such as Series, Equipment, Frame of Reference, Study and Patient.

The entities in Figure 7-2b, Figure 7-2c and Figure 7-2d correspond to IODs defined in Annex A, Annex B and Annex C.
