Amen to that! Funny! Instead of shaking all the bushes for engeneers and brothers of your next door neighbor's wife's cousin to give you advise on this thing. May I suggest the CEO of a cpmpany that has been tearing these things apart for many years and in fact knows so much about the guts of C-arms and MRIs, that should put any questions to rest. In fact this guy has a web site set up for more information.
