The present application discloses an ultrasound beamforming method for suppressing clutter, comprising: obtaining channel data of ultrasound echo signals; applying a conventional apodization function to the channel data of the ultrasound echo signals to obtain a signal dataset, and applying a random apodization function to the channel data of the ultrasound echo signals to obtain a noise dataset, wherein the random apodization function is obtained by orthogonalization of the conventional apodization function; calculating correlation coefficients of the signal dataset and the noise dataset in two directions within a coordinate system; calculating processed spatial data for each point in the ultrasound echo signal channel data based on the correlation coefficients and the signal dataset; forming the ultrasound beam based on the processed spatial data to generate imaging data. The present application utilizes the wideband characteristics of the random window which, when used in conjunction with the conventional apodization function, can better suppress sidelobes while preserving the main lobe, thereby improving image contrast and spatial resolution.

The present invention provides a pulsed Doppler ultra-high spectral resolution imaging processing method and processing system. The method includes: acquiring IQ signals corresponding to N sampling points respectively on each scan line; in a fast time direction, performing wall filtering processing to form an IQ signal wall filtering sequence; performing FFT on each sampling point in the IQ signal wall filtering sequence in a slow and a fast time direction, respectively, to obtain an energy distribution matrix at different frequency shifts; acquiring a velocity distribution matrix; and retrieving a velocity sequence for display, querying the velocity distribution matrix and the energy distribution matrix according to the velocity sequence, and acquiring an energy sequence corresponding to the velocity sequence for displaying a final spectrum. When a transmit signal bandwidth is wider or a scatterer velocity is faster, the velocity resolution is greatly guaranteed.
