What is the artifact called that appears when the ultrasound beam encounters strong reflectors leading to multiple echoes?

• A. Reverberation artifact
• B. Mirror image artifact
• C. Blooming artifact
• D. Side lobe artifact

Answer: (A)

The artifact that appears when the ultrasound beam encounters strong reflectors resulting in multiple echoes is known as a reverberation artifact. This phenomenon occurs when sound waves bounce back and forth between strong reflectors, such as tissue interfaces or metallic structures, before returning to the transducer. As a result, multiple echoes are generated, which can create a series of repeating, parallel lines on the ultrasound image. Reverberation artifacts can lead to misinterpretation of the image, as they may mimic real structures or cause confusion about the actual anatomy. Understanding this artifact is crucial for ultrasound technicians as it helps in distinguishing between true anatomical features and artifacts caused by the interaction of sound waves with strong reflectors.
