Abstract

The invention provides a spatial compounding method of an ultrasonic image and ultrasonic equipment. The method comprises the following steps: acquiring a deflection angle required for transmitting a plane wave; transmitting the plane wave according to the deflection angle to obtain a target frame number of plane wave images; determining an overlapping region of a pre-acquired frame of focused wave image and the target frame number of plane wave images; and carrying out spatial compounding on the overlapping region of the frame of focused wave image and the target frame number of plane wave images to obtain a frame of ultrasonic image. Therefore, the ultrasonic image is obtained by spatially compositing the overlapping area of the focusing wave image and the plane wave image of the target frame number. The resolution, the signal-to-noise ratio and the contrast ratio of the image can be ensured by the focused wave image, and the influence of artifacts such as speckle noise, clutter and sound shadow can be weakened after the focused wave image is fused with the plane wave, so that the problem that a relatively good image effect cannot be obtained during space compounding in the prior art is solved.

Description

technical field [0001] The present application relates to the field of ultrasound technology, in particular to a method for spatial compounding of ultrasound images and ultrasound equipment. Background technique [0002] In the ultrasound system, spatial compounding technology is usually used to suppress speckle noise, clutter, reverberation, sound shadow and other artifacts in the image. The principle of spatial compounding is to deflect the ultrasonic sound field by means of electronic delay, so as to obtain images of different deflection angles by scanning, and then weighted and superimpose the images of different deflection angles to obtain the final image. However, due to tissue movement or too large or too many spatial composite angles, the composite image will have motion blur, smearing, and stuttering. [0003] In the existing technology, the spatial compounding technology of plane waves is used to solve the phenomenon of motion blur, tailing, and stuttering of the ...
