At Emory university I got to see a cool idea to help kids get comfortable with MRI machines. Some Georgia Tech students built a fake MRI machine (a realistic mechanical structure with a sliding bed) that kids could still get into. The cool thing was that it had Bose speakers built into the fake machine so that they could play the sounds of a real MRI machine makes as that is a big aspect that makes kids get anxiety and fear of the machine.
It was all in a separate room right by the waiting room and the room with the real MRI. It was so cool to see such a practical solution to patient care especially for kids.
