Ultrasound speckle, which is caused by the interference of the backscattered ultrasound
signal, is considered to degrade image quality and is therefore unwanted in images. A variety of
research involving the statistical analysis of speckle has been performed and methods have thus
been developed to suppress or remove ultrasound speckle from images. Recent evidence has however shown that speckle contains useful information and is part of the signal. Research is
therefore currently needed to use speckle to assist recognition of formerly unrecognizable objects.
