Relier Pairs Ultrasound Physics ArtifactsVersion en ligne Match the Artifact to its description par Maryglo Stroik 1 artifacts degrade lateral resolution 2 Hyperechoic side-to-side region (appears the same as the foreground color) Results from increased intensity at the focus 3 2nd copy of a true reflector Artifact appears deeper than true 4 2nd copy of the reflector Copy is side by side, or at the same depth as the true reflector 5 Located beneath a structure with abnormally low attenuation (such as fluid-filled structures: bladder, gb, cysts) 6 appear as a single long hyperechoic echo located parallel to sound beams’ main axis 7 appear equally spaced are located parallel to the sound beam’s main axis are located at ever-increasing depths 8 Hypoechoic or anechoic region extending downward from a highly attenuating structure 9 The sound beam refracts at the edge of a curved reflector resulting in a drop of intensity. The decrease in intensity causes the shadowing 10 When medium’s speed is slower than that in soft tissue
