The reverberation artifact happens as a result of repetitive reflection back and forth between two highly reflective surfaces.  When the ultrasound beam reflects back and forth between the reflectors (“reverberates”), the ultrasound transducer interprets the sound waves returning as deeper structures since it took longer for the wave to return to the transducer.
