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.
Abstract:
According to an exemplary embodiment, an ultrasound apparatus for beamforming with a plane wave transmission may comprise a transceiver connected to a transducer array having at least one transducer element, and at least one processor. The transceiver transmits at least one substantially planar ultrasonic wave into a target region at one or more angles relative to the transducer array, and receives one or more signals responsive from the transducer array. The at least one processor applies a fast Fourier transform (FFT) to the one or more signals from each of the at least one transducer element and calculates at least one frequency within a frequency region, and applies an inverse FFT to at least one produced frequency data.
