Embodiment Construction

[0066] Below according to accompanying drawing and embodiment the present invention will be described in further detail:

[0067] figure 1 It is a flow chart of real-time medical three-dimensional ultrasonic imaging implemented by the invention, which simply describes the medical three-dimensional ultrasonic real-time imaging processing flow. This processing method is applicable to medical three-dimensional ultrasonic images, and has application value in medical three-dimensional imaging systems such as CT and MRI.

[0068] The present invention considers and focuses on solving the problem of fast realization of three-dimensional data reconstruction and visualization. Therefore, the present invention firstly solves the problem of three-dimensional data storage. In order to express enough information, the capacity of three-dimensional data is usually quite large. At present, the storage method of CPU memory is one-dimensional. If we simply follow the general image storage met...

Abstract

The invention provides a real-time medical ultrasonic three-dimensional imaging method, which is applicable to real-time acquisition of three-dimensional medical ultrasonic volume data which may be stored. Aiming at the characteristics of a current central processing unit (CPU) and the characteristics of a three-dimensional ultrasonic image, storage and access modes of three-dimensional data are optimized, and the conventional ray casting method is improved in combination with the knowledge of image morphology, so that the reconstruction and visualization of the three-dimensional data are quickly realized.

Description

technical field [0001] The invention relates to rapid reconstruction and visualization of three-dimensional medical images. Background technique [0002] The waveform diagrams and two-dimensional cross-sectional diagrams that traditional medical diagnosis and treatment rely on are not intuitive enough for observation. In this regard, Derek Ney formally proposed the concept of medical visualization for the first time in the SIGGRAPH Course in 1994, that is, transforming two-dimensional images into more intuitive and realistic three-dimensional images, which can be observed, analyzed and interacted from multiple angles and levels Operation, providing a safer, more reliable and accurate solution for medical diagnosis and treatment. [0003] Usually, according to the method of data description in the rendering process, the visualization of medical volume data can be divided into three categories: one is to describe the three-dimensional structure of the object by splicing and f...
