We present an enhanced block matching approach to improve displacement accuracy in ultrasound sequences using a combination of matching measures. The first measure uses the normalised cross correlation for regions of strong signal and the second measure CD2, specifically for regions of speckle determined by the speckle signal to noise ratio. We also show displacement field results for simulated speckle and in vitro data.
