Abstract

The invention is suitable for the technical field of ultrasonic contrast imaging, and provides a signal processing system and method based on the ultrasonic contrast imaging technology and terminal equipment. The system comprises a signal acquisition module and a signal processing module; the signal acquisition module is used for transmitting pulse waves, receiving the corresponding echo signals and sending same to the signal processing module; the signal processing module is used for extracting target frequency signals in the echo signals, obtaining the amplitude of the target frequency signals through calculation according to the target frequency signals, performing denoising processing on the amplitude of the target frequency signals through a Kalman filter, and obtaining the amplitude of the denoised target frequency signal. Noise signal interference is overcome, and the processing efficiency of the amplitude of the target frequency signal and the precision of the processing result are improved.

Description

technical field [0001] The present application belongs to the technical field of contrast-enhanced ultrasound imaging, and in particular relates to a signal processing system, method, terminal equipment and computer-readable storage medium based on contrast-enhanced ultrasound imaging technology. Background technique [0002] In contrast-enhanced ultrasound imaging technology, based on the collected echo signal, the amplitude of each frequency signal extracted is often applied in different technical fields. For example, due to the correlation between the amplitude of the sub-harmonic scattering signal in the echo signal and the environmental pressure, the amplitude of the sub-harmonic scattering signal is often used to estimate the blood flow pressure to obtain the blood flow pressure value. [0003] However, in general, the collected echo signal will carry a certain amount of noise signal, resulting in low accuracy of the amplitude of the extracted frequency signals, which ...
