Abstract

The invention provides an ultrasonic image processing method and device, and aims to solve the problem of how to improve the definition and contrast of edges of ultrasonic images on an image level. According to the invention, ultrasonic images are subjected to multi-scale decomposition, images of at least one scale is subjected to edge extraction, feature values and feature vectors of the images of the scale are obtained based on a structure tensor matrix, then the diffusion tensor is constructed based on the feature values and the feature vectors to improve the image quality, and therefore, the ultrasonic images are optimized by adopting a nonlinear diffusion method combined with an edge detection algorithm, and the edges and a contrast ratio of the ultrasonic images of the scale are optimized; then the ultrasonic images with multiple scales are reconstructed to obtain a high-quality ultrasonic image.

Description

technical field [0001] The present application relates to the technical field of ultrasonic image processing, in particular to an ultrasonic image processing method and device. Background technique [0002] Medical ultrasound imaging can be used to view the internal structure of diseased tissues in real time, and unlike CT, which has radiation damage, it is currently widely used in clinical examinations. [0003] However, compared with other medical images such as CT, ultrasound images have disadvantages such as unclear edges and low contrast. When there is a high demand for the edge definition of the lesion area during the diagnosis process, the defects of the ultrasound image may affect the diagnosis results of the clinician. [0004] For the problems of insufficient edge definition and low contrast of ultrasound images, it can be optimized from the signal level and image level. The optimization at the signal level is mainly to reduce the side lobe component, grating lob...
