Medical Definition of Echoes
1.
Wave packets (pulses) which have been reflected or otherwise returned to the detector, which are sufficiently delayed and retain sufficient magnitude so that they are perceived as a signal distinct from the one transmitted directly. (In other words, just like sound echoes, only for analogous phenomena with other waves.)
