Ultrasound imaging method and device and computer readable storage medium

Abstract

An ultrasonic imaging method and apparatus and a computer readable storage medium. The method comprises the steps of acquiring multi-angle imaging data in a plane wave imaging process, wherein the multi-angle imaging data is imaging data (S101)at multiple deflection angles; based on signal characteristics, calculating correlation coefficients between imaging data at adjacent angles in the multi-angle imaging data, wherein the imaging data at adjacent angles is imaging data (S102) corresponding to two adjacent deflection angles of the plurality of deflection angles; according to correlation coefficients, obtaining enhancement coefficients positively correlated with the correlation of the imaging data the adjacent angles, wherein the enhancement coefficients are coefficients (S103) corresponding to the multi-angle imaging data; and processing the multi-angle composite data or the multi-angle imaging data by using the enhancement coefficients to obtain an enhanced image (S104). The method can reduce the noise in the composite image and improve the contrast resolution of the composite image.

Description

technical field [0001] Embodiments of the present invention relate to the field of ultrasound imaging, and in particular, to an ultrasound imaging method and device, and a computer-readable storage medium. Background technique [0002] In recent years, compared with the traditional focused imaging technology, ultrasonic plane wave technology has the advantages of less number of shots and higher imaging frame rate, which makes ultrasonic plane wave technology available in imaging modes such as contrast imaging, elasticity, conventional two-dimensional and color blood flow. widely used. At the same time, the difference in the transmission mode between ultrasonic plane wave technology and traditional focused imaging technology leads to insufficient penetration and poor lateral resolution of plane wave images. In order to solve the problems of insufficient penetration and poor lateral resolution of plane wave images, Coherent angle compounding technology has become an essential...

[0003] However, there are noise and clutter in the echo signal. When the proportion of noise and clutter in the echo signal is greater than that of the useful signal in the echo signal, the correlation between useful signals at various angles is will be reduced. At this time, directly superimposing the beamforming data from multiple angles will increase the noise in the composite image, thereby reducing the contrast resolution of the composite image.
