Well Tinker, the question revolves around the fact that although there is no stipulated requirement to have previously undertaken an X-Ray the Immigration Officers at some UK airports have the power to ask you to either show an X-Ray or to have it done at the airport. This can lead to unwanted delays.
The answer is that if you already do have an X-Ray, it's better to bring that with you as it may save a considerable delay etc.
Whether or not the Immigration Officer will ask is not known or predicatable
