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.
