Speckle noise affects the quality of the ultrasound images and can mask pathology. This artifact can be reduced by using a phase insensitive technique, or by canceling the undesirable linear-phase representation. More system samplings (needs more channels and memory) or a fuzzy logic algorithm can filter out the speckle noise.
