MM.2.8 A “Single-Frame” Multi-Frame Image

The requirement that the newly created image object generated in response to a Frame level retrieve request must be the same as the SOP class will frequently result in the need to create a single frame instance of an object that is more commonly a multi-frame object, but this should not cause any problems with the IOD rules, as all such objects may quite legally have Number of Frames = 1.

However, a single frame may well cause problems for a transfer syntax based on “video” such as those using MPEG-2, and therefore the SCU when negotiating a C-GET should consider this problem, and include one or more transfer syntaxes suitable for holding single or non-contiguous frames where such a retrieval request is being made.
