Different types of reverberations which may cause confusing artifacts in echocardiograms are described. Reverations between the targets may result in identifiable complex echo patterns. An echocardiogram with reverberating echoes is presented. Several experimental studies were done to explain the reverbating echoes. The reverberating echoes may be more prominently displayed than the primary echoes. This raises the possibility of obtaining useful information from the reverberating echoes.
