1. A magnetic resonance apparatus for examining a subject, comprising:

  • a) a region in which the subject is positioned during examination;

    b) radio frequency means for applying a radio frequency field having a frequency to the region for producing magnetic resonance in the subject; and

    c) a transducer disposed in the region and having a lead which is grounded to signals having the frequency of said radio frequency field at a distance along the lead from the transducer which is equal to a quarter wavelength at said radio frequency field frequency or to an odd multiple thereof.
