Abstract:
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; andproducing 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; anddetecting 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.
