## KKK.5 Query and Retrieval

The coexistence (either actually or logically) of two different representations of the same information creates a potential challenge in that the user must not be presented with both sets simultaneously.

A naïve conversion that added converted images to the study without an ability to distinguish or "filter" them from view would not only be confusing but would potentially result in twice as much data to transfer.

Accordingly, the Query/Retrieve mechanism is extended with an optional extended negotiation capability to specify which "view" of the information is required by the SCU:

- A "classic" view, which includes either original (as received) classic single frame images or enhanced multi-frame images converted to single frame.

- An "enhanced" view, which includes either original (as received) enhanced multi-frame images, or classic single frame images converted to true or legacy converted enhanced multi-frame.
