I would used instructional videos for postioning on youtube, during my two years in the radiology progarm, for example, Chest x-ray. The narrigator explains step by step on what has to be done to obtain a diaganostic image. She also explains what to look for in the image to make sure it is of diaganostic quality. The videos are very helpful and useful for people who have knowledge withing the field. If an average person who has no knowledge in the field were to watch the video they would not comprehend the procedure. The terminology is going to seem as if it is from another planet.
