Q. E/R Model

The E/R Model consists of Patient and Structured Information, with no relationship to other Information Entities in the DICOM Information model.


Figure Q.4-1 Relevant Patient Information E/R Model

The Patient IE includes the attributes of the Patient Identification and Patient Demographics Modules.

The Structured Information IE includes attributes that are not inherently related to a real-world entity, but are interpreted through their coded content. This includes the attributes of the Structured Document Content Module, which in the case of the Relevant Patient Information Query Service has its content constrained by specified templates to convey patient related information. Also included in the Structured Information IE are attributes of the SOP Common and Common Instance Reference Modules that support the interpretation of coded data, or support access to referenced information objects identified in the coded data.
