    Whew, not sure I can help with this one. Have you tried a google search for radiologic technologists? They may have a forum similar to this and be more equipped to answer these types of questions. Good luck! -- D

    this is a little late, but a good forum to try is www.radiography.com there are a few really knowledgeable techs that post there who can help you out. I would try but I am a student myself and still working on this stuff!
