Abstract

The invention relates to the technical field of ultrasound, in particular to an ultrasonic image noise reduction method and electronic equipment, and is used for solving the problem of how to well suppress speckle noise and well maintain edge information during image filtering. According to the invention, only the image in the window is filtered by setting the filtering window. And if the image quality in the window is greater than the image quality threshold, it is proved that the image quality is relatively high, and at the moment, the Lee filtering algorithm is adopted for filtering, so that the edge information of the image can be ensured while the speckle noise is suppressed. If the image quality in the window is smaller than or equal to the image quality threshold value and the size of the filtering window is smaller than the window minimum value, it is proved that the image quality is low, at the moment, a gradient operator is adopted for filtering, the problem that the speckle noise suppression effect is not ideal is avoided, and edge information is prevented from being damaged.

Description

technical field [0001] The present application relates to the field of ultrasound technology, and in particular, to a noise reduction method and an electronic device for an ultrasound image. Background technique [0002] In the related art, the Lee filtering method is usually used to filter the ultrasound image. The classic Lee filter denoising algorithm is built on the fully developed multiplicative model of coherent speckle noise points, and the suppression effect of underdeveloped coherent speckle noise is not ideal. The improved Lee filter denoising can effectively suppress coherence. speckle noise, but the edge information is destroyed. Therefore, it is necessary to solve the problem of how to suppress the speckle noise well and keep the edge information well when filtering the image. SUMMARY OF THE INVENTION [0003] The present application discloses a noise reduction method and electronic device for an ultrasonic image, which are used to solve the problem of how t...
