Abstract

An operating method for an ultrasound transceiver device, where the ultrasound transceiver device is alternately and, in particular alternatingly operated in a transmit mode and in a receive mode; subsequently to a transmit mode and/or prior to a receive mode, the ultrasound transceiver device is actively damped by the action of a sequence of counter control pulses; a phase position and/or a damping energy are/is iteratively determined or adapted via a training by a measure of the damping success at least temporarily assuming or approaching an at least locally optimal value.
