1. An ultrasonic imaging probe comprising:

  • an elongate probe guide assembly;

    transducer means connected near a distal end of said probe guide assembly for transmitting/receiving ultrasonic waves along a first path; and

    electrical cable means which includes a two lead cable housed within said probe guide assembly and operatively connected to said transducer means for transmitting electrical signals to, and receiving electrical signals from, said transducer means;

    said electrical cable means including an inductor coil coaxially housed within said probe guide assembly and having proximal and distal ends, said inductor coil being positioned closely adjacent said transducer means such that said inductor coil distal end is electrically connected to said transducer means, and whereinone of said leads of said cable being electrically connected to said proximal end of said inductor coil, and another of said leads of said cable being electrically connected to said transducer means at a location different from said electrical connection of said inductor coil distal end thereto, whereby said one cable lead, inductor coil, transducer means and said other cable lead are in series connection.
