Abstract
An ultrasonic diagnostic imaging system and method filter the data of successive ultrasonic images of moving tissue. At least two successive images are clutter filtered to remove clutter in the image data from stationary objects. The successive images and the filtered successive images are both used to produce displacement images of frame to frame tissue motion, and a quality metric is produced of the quality of the estimated displacement. The displacement image with the best quality metric is selected for further processing such as the production of strain images. The selected displacement image may further be spatially filtered to reduce boundary artifacts.
