Abstract
An ultrasonic diagnostic imaging system and method are described which perform spatial compounding of tissue motion or flow information. The resultant images not only reduce speckle artifacts, but also reduce dropout caused by the angular dependence of Doppler information. Compound images may be formed using both B mode and Doppler information acquired in a time interleaved manner, either one or both of which may be spatially compounded. The techniques of the present invention may be employed to reduce multiline artifacts and to produce real time compound images at high frame rates of display.
