Embodiment Construction
[0041] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0042] The main solution of the processing method of the ultrasonic signal that the embodiment of the present invention proposes is:
[0043] Obtain the radio frequency signal received by each array element channel, and at least two sets of pre-stored apodization weight values;
[0044] generating at least two ultrasound image signals based on at least two sets of the pre-stored apodization weight values and the radio frequency signal;
[0045] Obtain a confidence estimation result corresponding to each of the ultrasound image signals, and a correlation estimation result of each of the ultrasound image signals with respect to other ultrasound image signals, wherein the other ultrasound image signals are the at least two ultrasound image signals Among the image signals, other ultrasound image signals except itself; ...

The invention discloses an ultrasonic signal processing method which comprises the following steps: acquiring a radio frequency signal received by each array element channel and at least two groups ofpre-stored apodization weight values; generating at least two ultrasonic image signals based on the at least two groups of pre-stored apodization weight values and the radio frequency signals; obtaining a confidence estimation result corresponding to each ultrasonic image signal and a correlation estimation result of each ultrasonic image signal relative to other ultrasonic image signals, the other ultrasonic image signals being other ultrasonic image signals except itself in the at least two ultrasonic image signals; and synthesizing a target ultrasonic image signal based on the confidence estimation result, the correlation estimation result and the ultrasonic image signal. The invention further discloses ultrasonic signal processing equipment and a computer readable storage medium, andthe effect of improving the resolution of the ultrasonic image is achieved.
Description
technical field [0001] The invention relates to the field of ultrasonic technology, in particular to an ultrasonic signal processing method, an ultrasonic signal processing device and a computer-readable storage medium. Background technique [0002] Ultrasound imaging is widely used in multidisciplinary medical practice to assist doctors in diagnosis and treatment. The existing clutter suppression method based on multi-apodization technology generally obtains a pair of complementary array element full-channel signals by using two complementary apodizations, and then obtains a corresponding signal weight through the cross-correlation of this pair of signals , and finally the weight is multiplied by the original normal DAS (Delay And Sum, delay summation) result to obtain the image signal after clutter suppression. [0003] However, the above-mentioned signal processing method can only suppress the image clutter, and the effect is not much different from manually reducing the...
