发明名称 Method for reducing ultrasound data
摘要 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 td, 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.

主权项 1. A method for reducing ultrasound data from an ultrasound signal comprising a plurality of ultrasound pulses, the method comprising: a) rectifying the ultrasound signal, b) generating an envelope curve about the maximum values of the rectified ultrasound signal, wherein each of the ultrasound pulses is represented as a curve portion with a single maximum value, c) producing 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 td, for each of the ultrasound pulses, d) adding the first negative envelope curve signal and the delayed envelope curve signal to form a first sum signal with a first zero crossing, wherein the first zero crossing represents a first time value, and e) associating an amplitude 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.
