1. A method for producing an ultrasonic image of interpolated image lines with reduced susceptance to motion artifacts including at least one level of interpolation comprising the steps of:

  • transmitting a plurality of laterally spaced ultrasonic beams along transmit beam locations in an image field;

    receiving a plurality of laterally spaced receive beams which are located laterally on opposite sides of the transmit beam location in response to each transmitted beam; and

    producing interpolated image lines from said receive beams, which comprise interpolated image lines, at least some of which are formed from temporally different receive beams located on opposite sides of a transmit beam location; and

    detecting and displaying said interpolated image lines, wherein each of the interpolated image lines formed at each level of interpolation are formed from a plurality of temporally different lines.
