# 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.
