## V.5 Hanging Protocol Query Example

The following is an example of a general C-FIND Request for the Hanging Protocol Information Model - FIND SOP Class that is searching for all Chest related Hanging Protocols for the purpose of reading projection Chest X-ray. The user is at a workstation that has two 2Kx2.5K screens.

C-FIND Request:

The following is an example of a set of C-FIND Responses for the Hanging Protocol Information Model - FIND SOP Class, answering the C-FIND Request listed above. There are a few matches for this general query. The application needs to select the best choice among the matches, which is the second response. The first response is for Chest CT, and the third response does not match the user's workstation environment as well as does the second.
