超声图像广泛应用于工业，海洋，医学等领域并且在诸多领域起到不可替代的重要作用。但大规模乘性噪声严重影响了超声图像的成像质量。无法精准判读超声图像，制约着超声图像应用的发展。为此，提出超声图像大规模乘性噪声干扰的过滤算法，通过对超声图像成像像素进行像块分解重组重构出大规模乘性噪声部分，运用滤波函数公式提取出大规模乘性噪声干扰量，建立超声图像大规模乘性噪声过滤模型将乘性噪声干扰进行过滤计算，重构更为清晰的超声图像的过程。仿真实验证明，超声图像大规模乘性噪声干扰过滤算法有效的抑制了大规模乘性噪声对图像质量的影响，更好的保留了超声图像的细节信息。

Ultrasound images are widely used in industrial, Marine, medical and other fields and play an irreplaceable role in many fields. But massive multiplicative noise seriously affects the image quality of ultrasound images. Can't accurate in?terpretation ultrasound images, it restricts the development of ultrasonic image application. For this purpose, the ultrasonic image of mass multiplicative noise filtering algorithm, based on ultrasonic imaging image pixel as a decomposition refactor?ing a massive multiplicative noise, using the filter function formula to extract the massive amount of multiplicative noise, ul?trasound image massive multiplicative noise filtering model is set up to multiplicative noise filtering calculation process. Simulation experiments show that ultrasonic image massive multiplicative noise filtering algorithm effectively suppress the influence of massive multiplicative noise on image quality, better keep the details of the ultrasound images.
