Problems solved by technology

[0010] Taking this method as an example, when imaging a violently moving target, on the one hand, there is a certain time interval between the spatially compounded multi-frame images, and motion blur will be introduced through the weighting between multiple frames; on the other hand, ultrasonic The overall grayscale distribution of the image is dominated by medium and low grayscales, and the proportion of higher grayscale areas such as tissue boundaries is small; thus, the temporal compounding algorithm cannot completely remove the large grayscale changes caused by violent motion between two frames of images , and temporal compounding is based on IIR filters, resulting in the tissue information of the first frame image in the scanning sequence still having an impact on subsequent frame correlation results, resulting in motion blur

Abstract

The invention provides an ultrasonic image time domain filtering method for weakening motion blur, equipment and a medium, and the method comprises the steps: introducing a motion degree to adjust a correlation coefficient between frame data when the time recombination of the frame data at different moments is carried out. noise is effectively suppressed, motion blur caused by time recombination is weakened, and the imaging effect is improved.

Description

technical field [0001] The invention relates to the field of medical equipment imaging, in particular to a time-domain filtering method, equipment and medium for ultrasonic image for reducing motion blur. Background technique [0002] In medical ultrasound imaging systems, random noise and speckle noise are the most common factors affecting image quality. Random noise is mainly electronic noise, which shows the characteristics of random distribution in the image space and at different times. Speckle noise is formed by the mutual interference of the echo signals of the scattering medium in the tissue. Since the movement of human tissue and the movement of the probe will change the distribution of speckle noise during ultrasound imaging, the distribution of speckle noise on different images also has a certain degree of randomness. Ultrasound systems often use techniques such as space compounding, time compounding, and frequency compounding to reduce the impact of noise on im...
