The embodiments of the present disclosure disclose a filtering method and system for ultrasonic imaging. The method may include: obtaining a plurality of pulse Doppler echo signals, two adjacent pulse Doppler echo signals being distributed at intervals in a time domain; generating a plurality of discontinuous segments of IQ data by demodulating the plurality of pulse Doppler echo signals; for each segment of IQ data, performing first filtering on at least part of data points; and obtaining a segment of filtered IQ data by performing second filtering on the filtered data points and unfiltered data points; performing interpolation based on the plurality of segments of filtered IQ data; and generating a spectrum image based on the interpolated data.

Filtering method and system for ultrasonic imaging

The embodiments of the present disclosure provide a method and a device for signal processing. The method includes: obtaining multiple sets of initial Doppler blood flow signals, sampling times of the multiple sets of initial Doppler blood flow signals being discontinuous; and performing a splicing processing on the multiple sets of initial Doppler blood flow signals, to obtain a target Doppler blood flow signal.

Methods and devices for splicing ultrasound signal

The present disclosure provides a method for ultrasound image processing. an ultrasound image may be obtained. The ultrasound image may be associated with the blood flow velocity. An envelope curve may be determined based on ultrasound image. A plurality of first maximum points of the envelope curve may be determined. A plurality of second maximum points may be obtained by screening the plurality of first maximum points based on amplitude features of the plurality of first maximum points. A plurality of third maximum points may be obtained by correcting the plurality of second maximum points according to time features of the plurality of second maximum points. One or more parameters relating to the blood flow velocity may be determined based on the plurality of third maximum points.
