The B-mode image is a black image on one half. and speckles on the other half.</p> <p>Additionally, the harmonic image is pitch black as well. </p> <p>I am trying to create an image with minimum speckles but changing the background mean seems to have a very weird effect. What am I missing in the understanding of this process? </p>
