Ultrasonic imaging device operating method for preventing aliasing

摘要

The operating method has a number of ultrasonic beams with respective focal points provided by an ultrasonic transducer array in a given plane, with a pair of complex signals of limited bandwidth obtained from the detected ultrasonic reflections received by the transducer array. Each complex signal is provided by a number of samples which are interpolated, for increasing the sampling rate and providing an envelope curve for each complex signal, used for providing an image display
