re·ver·ber·a·tion

(rē'ver-bĕr-ā'shŭn),
Multiple echoes or reflections; in ultrasonography, an artifactual image caused by delay of an echo that has been reflected back and forward again before returning to the transducer.

reverberation

/re·ver·ber·a·tion/ (-ver″bĕ-ra´shun) duration of neuronal activity well beyond an initial stimulus due to transmission of impulses along branches of nerves arranged in a circle, permitting positive feedback.

reverberation

[rivur′bərā′shən]
1 the phenomenon of multiple reflections within a closed system.
2 an artifact in ultrasound caused by multiple echoes from parallel tissue interfaces.

reverberation

an artifact in ultrasound imaging resulting from the production of spurious echoes which are caused by reflections at the skin-transducer interface or by bone or gas. See also comet-tail.
