Web7 mrt. 2024 · Acoustic shadowing (sometimes referred to as posterior acoustic shadowing) is a form of ultrasound artifact. It is characterized by the apparent lack of signal deep to an imaged tissue interface, due to all (or nearly all) of the transmitted sound wave being being reflected back to the transducer or absorbed by the tissue. WebUltrasound gel is applied to the patient’s skin, so the sound is able to travel through the body and return to the transducer. The transducer’s receiver detects any deviations in the sound as it bounces off different parts of the body’s internal workings, from tissues to organs. These sound waves are measured, and create an image on a ...
