Abstract

A method for rebuilding 3D ultrasonic image includes such steps as primary systematic scaling, obtaining 2D image, initializing parameters, correcting data, rebuilding 3D data, evaluating 3D image, and regulating parameter values.

Description

Technical field: [0001] The invention belongs to a digital image processing method, in particular to a three-dimensional ultrasonic image reconstruction method, which is used for medical or industrial ultrasonic image equipment to realize three-dimensional imaging. Background technique: [0002] Three-dimensional ultrasound is a new imaging method produced by scanning reconstruction on the basis of two-dimensional ultrasound. It overcomes the problem that the three-dimensional information of the imaged object cannot be described in two-dimensional imaging, so that the measurement of volume and distance Measurement and display and description of spatial shapes are possible. [0003] The reconstruction method of 3D ultrasound depends on the scanning method used. Mechanical scanning has been widely used because of its small distortion of the reconstructed image and is suitable for application in interventional therapy. Mechanical scanning includes three modes: parallel scannin...
