1. A method for measuring transducer movement for multi-dimensional ultrasound imaging, the method comprising:

  • positioning a transducer at an angle other than perpendicular to a skin surface;

    translating at least a portion of the transducer on the skin surface;

    measuring, from ultrasound data, a first distance of the transducer translation during translating, the first distance being a function of the angle; and

    determining a second distance of the transducer translation with an optical sensor responsive to patient tissue of the skin surface.
