摘要：
A method for examining the interior material of an object, such as a pipeline or a human body, from a surface of an object using ultrasound having a frequency of at least 100 KHz, wherein the ultrasound is supplied to the interior material of the object. The reflections and/or diffractions of the ultrasound from the interior material of the object are received using ultrasonic receivers which are acoustically coupled to the surface of the object at positions which are distributed in two dimensions of the surface of the object, at different points in time or not, wherein, with each of the feelers, a receiving signal is generated, wherein the receiving signals are processed in combination in order to determine, according to the principle of inverse wave field extrapolation, where in the interior material of the object reflections and/or diffractions occur.
摘要（中）：
一种用于使用频率至少为100KHz的超声从物体表面检查物体（例如管道或人体）的内部材料的方法，其中超声波被提供给物体的内部材料。 使用超声波接收器接收来自物体的内部材料的超声波的反射和/或衍射，所述超声波接收器在物体的表面的两个维度上分布在物体表面的位置处声学耦合到物体的表面， 时间与否，其中，对于每个触发器，产生接收信号，其中组合处理接收信号，以便根据反波场外推的原理确定在物体反射的内部材料中 和/或衍射。
