Ultrasonic imaging method and device, and computer-readable storage medium

Abstract

An ultrasonic imaging method and device, and a computer-readable storage medium, the method comprising: acquiring multi-angle imaging data during the plane wave imaging process, the multi-angle imaging data being imaging data at multiple deflection angles (S101); , calculate the correlation coefficient between the adjacent angle imaging data in the multi-angle imaging data, the adjacent angle imaging data is the imaging data corresponding to two adjacent deflection angles among the multiple deflection angles (S102); according to the correlation coefficient, the corresponding The enhancement coefficient of the positive correlation of the correlation of the adjacent angle imaging data, the enhancement coefficient is the coefficient corresponding to the multi-angle imaging data (S103); using the enhancement coefficient, the multi-angle composite data or the multi-angle imaging data are processed to obtain the 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.
