1. An ultrasound medical imaging system, comprising:

  • an ultrasound probe;

    a positioning device having;

    a linkage with at least two rigid arms, wherein one end of said linkage is a free end that is operative to move in three dimensions and wherein said free end is configured to be locked in a fixed position;

    a rotational shaft interconnected to the free end of said linkage;

    a rotary encoder configured to generate an angular outputs indicative of an angular orientation of said rotational shaft about said rotational axis;

    a vibratory actuator for controllably imparting a vibration in said rotational shaft between a reference position and a displaced position, wherein said vibratory actuator moves said rotational shaft in a non-rotational direction; and

    an ultrasound probe holder attached to said rotational shaft for releasable holding an acquisition array of the ultrasound probe in a known position relative to a rotational axis of said rotational shaft;

    an ultrasound system for acquiring a plurality of two-dimensional ultrasound images in conjunction with rotation of said rotational shaft about said rotation axis and vibration of said rotational shaft, wherein each of said plurality of two-dimensional image are acquired while said rotational shaft is in said reference position;

    a registration system configured to;

    receive said angular outputs from said rotary encoder;

    receive said plurality of two-dimensional ultrasound images; and

    utilize said angular outputs to register said plurality of two-dimensional ultrasound images into a three-dimensional ultrasound image; and

    a display configured to display said three-dimensional ultrasound image.
