Cranfield University should apply to BSI (UK ANSI Body) for its own organisational code. However, given that all the ultrasound scanners are installed and will not be replaced for the duration of the trail it seems reasonable to apply an unofficial organisational code (999999) without there being an danager of a conflict. We also append a revision number to the end of the string which is incremented each time the image (or record) is updated. The advantage of this approach is that the original SOPInstanceUID can be reconstituted, if ever necessary.
