The current state-of-the-art spatial compounding imaging technology causes undesirable smearing on moving tissue due to its low effective frame rate. This disadvantage makes spatial compounding less useful for vascular and/or cardiac applications. The present invention provides a solution for these clinical situations, in that spatial compounding is performed only in the region of interest (ROI). By using this technique, the total number of vectors fired per compound image is reduced dramatically compared to the conventional spatial compounding technique. This invention allows user to take advantage of the spatial compounding while keeping high resolution and high frame rate. It is especially useful in vascular/cardiac applications when tissue is constantly moving.
