## DD.1 Examples For The Usage of The Modality Worklist (Informative)

These typical examples of Modality Worklists are provided for informational purposes only.

- A Worklist consisting of Scheduled Procedure Step entities that have been scheduled for a certain time period (e.g., "August 9, 1995"), and for a certain Scheduled Station AE title (namely the modality, where the Scheduled Procedure Step is going to be performed). See Figure DD.1-1.

- A Worklist consisting of the Scheduled Procedure Step entities that have been scheduled for a certain time period (e.g., "August 9, 1995"), and for a certain Modality type (e.g., CT machines). This is a scenario, where scheduling is related to a pool of modality resources, and not for a single resource.

- A Worklist consisting of the Scheduled Procedure Step entities that have been scheduled for a certain time period (e.g., "August 9, 1995"), and for a certain Scheduled Performing Physician. This is a scenario, where scheduling is related to human resources and not for equipment resources.

- A Worklist consisting of a single Scheduled Procedure Step entity that has been scheduled for a specific Patient. In this scenario, the selection of the Scheduled Procedure Step was done beforehand at the modality. The rationale to retrieve this specific worklist is to convey the most accurate and up-to-date information from the IS, right before the Procedure Step is performed.

The Modality Worklist SOP Class User may retrieve additional Attributes. This may be achieved by Services outside the scope of the Modality Worklist SOP Class.
