Abstract: A method of ultrasound imaging and a corresponding ultrasound scanner are provided. The method includes the steps of receiving an echo signal induced by an ultrasonic plane wave transmission from a transducer of an ultrasound scanner, resampling the echo signal in time domain and/or space domain, performing a spectrum zooming on a band of interest (BOI) of an input signal, performing a Fourier transform on a result of the spectrum zooming, and generating an ultrasound image based on a result of the Fourier transform. The input signal is generated based on the resampling of the echo signal.
