    So, if the MRI spins at 12 RPM, does the dude also spin at 12 RPM?

    Asking for a friend.

      The detector spins around the patient, but does the magnetic field spin too? I though not, but I’m not that certain.

        Nope, the detector is separate from the magnet - the magnet encircles the patient completely, and doesn’t move. I’m sure the magnetic field is affected slightly by the rotating machinery, but that should be consistent and predictable, and would be accounted for in the imaging algorithms.

          Yeah I considered the supercooled electromagnert couldn’t possibly rotate, but I wasn’t sure if it could be modulated to change field directions or something. Didn’t seem very likely. Thanks for the confirmation.
