Speckle artifact may be encountered in ultrasound. It is caused by the scattering of waves from the surface of small structures within a certain tissue. The artifact produces a textured appearance.
Because speckle can make it harder to distinguish soft tissue differences, modern ultrasound machines are able to reduce speckle through various techniques known as 'despeckling' 2.
