摘要： In a high resolution ultrasonic tomograph operating according to transmission, scattering and impulse-echo methods, comprising a container with an open top and including ultrasonic transducers arranged along the walls of the container, a coupling medium disposed in the container and a computer-based control and evaluation unit with a working memory, the control and evaluation unit is connected in a circuit with the ultrasonic transducers in such a way that the ultrasonic signal emitted from at least one ultrasonic transducer forms an ultrasonic impulse which is received by all the other transducers in parallel and is amplified, filtered and digitized to form electric signals which are stored in the working memory as a data set.

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.
摘要翻译：一种用于从超声波信号中减少超声数据的方法包括对超声信号进行整流，并产生关于整流超声信号的最大值的包络线。每个超声波脉冲被表示为具有单个最大值的曲线部分。产生被第一因子f减小的第一负包络线信号和不被修改但被延迟时间段td的延迟包络线信号。第一负包络线信号和延迟包络线信号被相加以形成具有第一零交叉的第一和信号，其中第一零交叉表示第一时间值。振幅与第一时间值相关联，幅度对应于在与第一时间值相关的时间间隔内与包络线的最大峰值高度一致的信号高度。
