The DICOM Model of the Real World is extended for a variety of non-patient-related information with the specification of entities that are generally separate from the rest of the DICOM Real World Information Model. These information entities are not associated with a specific Patient. While there may be entity relationships, there is no hierarchy applied to these entities.
A Hanging Protocol Information Entity specifies the viewing preferences of a specific user or group, for a specific type of Study (Modality, Anatomy, Laterality combination, and optionally Procedure, and/or Reason). A Hanging Protocol definition includes descriptors that identify the Hanging Protocol, the creator, the type of Study it addresses, the type of image sets to display, the intended display environment, and the intended layout for the screen(s).
The Hanging Protocol IE does not have any relationships with other Information Entities. See Figure 7.13-1.
