Abstract
An ultrasonic diagnostic imaging system and method are provided for producing r.f. interpolated image lines with reduced susceptibility to motion artifacts. A multiline beamformer receives multiple scanlines in response to each transmitted beam. Image lines are produced by r.f. interpolation of these multiline scanlines in a temporally consistent manner. In an illustrated embodiment, each image line is produced by tle interpolation of scanlines produced in response to at least two transmitted beams. In a preferred embodiment the interpolated image lines are produced by a [1 2 1] lateral filter.
