Abstract
A method for reducing ultrasound data from an ultrasound signal includes rectifying the ultrasound signal and generating an envelope curve about maximum values of the rectified ultrasound signal. Each ultrasound pulse is represented as a curve portion with a single maximum value. A first negative envelope curve signal, which is reduced by a first factor f, and a delayed envelope curve signal, which is not modified but is delayed by a time period t, are produced. The first negative envelope curve signal and the delayed envelope curve signal are added to form a first sum signal with a first zero crossing, wherein the first zero crossing represents a first time value. An amplitude is associated with the first time value, the amplitude corresponding to a signal height consistent with a maximum peak height from the envelope curve within a time interval about the first time value.
