Rebuilding method of real-time three-dimensional medical ultrasonic image

Abstract

The present invention provides a real time three-dimensional medical ultrasonic image reconstruction method, including steps in sequence: (1) preprocessing volume image data from an ultrasonic three-dimensional sensor to acquire required volume image data for reconstructing image; (2) classifying data points of the volume image data acquired in step (1), wherein data points of same material are classified into one classification; (3) executing value assignment to the data points, wherein the value assignment includes color value assignment and opacity coefficient value assignment to the data points; (4) executing three-dimensional transformation of coordinates of the volume image data in an image processor, wherein hexahedron data are converted into hyperboloid data; (5) resampling in theimage processor and converting original coordinate of data points into coordinate of data points in hyperboloid data; (6) synthesizing image. According to the invention, not only original image data are not lost, but also real-time display of image can be realized, thereby realizing real time reconstruction of three-dimensional medical ultrasonic image, and enabling finally formed image to truly reflect true forms of the tested objects.

Description

technical field [0001] The invention relates to image data processing, in particular to a method for reconstructing real-time three-dimensional medical ultrasonic images. Background technique [0002] The visualization and interpretation of traditional medical two-dimensional images has been widely accepted, but after the invention of volume image technology, since each volume image data (ie three-dimensional image data) contains a series of two-dimensional slices (ie two-dimensional image data) , the number of 2D slices that must be viewed is exploding, creating an urgent need to more intuitively observe volumetric image data. [0003] The main purpose of 3D visualization is to use computer graphics technology to construct a 3D model of an organ from a series of 2D slices obtained by medical imaging equipment (this series of 2D slices constitute volume image data), and it is very realistic. is displayed to the viewer, so that the viewer can intuitively observe the volumetr...

Problems solved by technology

However, the volume image data obtained by the image processing device from the ultrasonic three-dimensional sensor is actually cube data, that is, the volume image data obtained from the ultrasonic three-dimensional sensor consists of a series of parallel two-dimensional slices, and these two-dimensional slices are stored in the memory according to Arranged in chronological order, the image formed according to the cube data does not match the measured object, which will cause shape distortion and deformation, and cannot truly reflect the actual shape of the measured object
