Processing method and device for space composite imaging

Abstract

Embodiments of the invention provide a processing method and device of space composite imaging. The processing method of space composite imaging includes the steps that at least one first ultrasound image is acquired, and each of the first ultrasound images corresponds to a scanning line of an initial deflection angle; according to the at least one first ultrasound image, virtual scanning vertices, the deflection angle of each scanning line and the weights corresponding to each scanning line are adjusted; and according to the adjusted virtual scanning vertices and the adjusted deflection angleof each scanning line, the scanning lines are controlled to be transmitted and received to obtain at least three second ultrasound images, each of the second ultrasound images corresponds to one scanning line with a deflection angle, and according to the weights corresponding to the adjusted scanning lines and the at least three second ultrasound images, the at least three second ultrasound images are subjected to space composite imaging. According to the embodiments, the quality of space composite imaging can be improved.

Description

technical field [0001] Embodiments of the present invention relate to medical ultrasonic diagnostic technology, and in particular to a processing method and device for spatial composite imaging. Background technique [0002] With the continuous development of science and technology, ultrasonic scanning diagnostic systems are more and more widely used in medicine, and the application of spatial composite imaging technology can improve the details of images, while reducing speckle noise, clutter, and acoustic noise in images. The impact of shadows and other ultrasound artifacts on image quality enhances the ability to distinguish between tissues. [0003] Among them, the spatial compound imaging technology scans the target tissue from different angles through the deflection of the scanning line, and after obtaining images from different angles, weights and sums the corresponding pixel points of these images to synthesize an image. Wherein, both the weighted weight and the def...

Problems solved by technology

[0004] However, the edge of the general tissue or the blood vessel wall will be curved, and the deflection of several fixed angles will cause the edge information of the tissue or the edge information of the blood vessel wall to not be perpendicular to the deflection angle, resulting in the problem of discontinuous border display
