Which artifact is produced when a smooth, flat object causes the beam to reflect multiple times, leading to a series of linear echoes?

Which artifact is produced when a smooth, flat object causes the beam to reflect multiple times, leading to a series of linear echoes?

• A. Reverberation
• B. Anisotropy
• C. Edge Effect
• D. Acoustic Shadowing

Answer: (C)

Reverberation artifacts occur when the ultrasound pulse keeps bouncing back and forth between a strong, smooth reflector and the transducer. Each round trip generates another echo that returns to the transducer, so you see a series of echoes at progressively greater depths. This creates a ladder-like sequence of linear echoes along the same line, which is the hallmark of reverberation. Edge-related artifacts arise from interactions with the boundaries of curved surfaces and appear differently—often near edges rather than as a regular stack of echoes. Acoustic shadowing and anisotropy involve attenuation or angle-dependent appearance, not repeated linear echoes. So the scenario described—multiple reflections producing a series of linear echoes—best matches reverberation.
