Design of three-dimensional visualization system for medical image based on magnetic resonance angiography data

Objectives: The objective of the study was to discuss the design method of medical image three-dimensional (3D) visualization system based on magnetic resonance angiography (MRA) data. Methods: Using 3D visualization of the carotid artery as an example, the three-position reconstruction algorithm on the basis of volume rendering was discussed. Moreover, if 3D carotid artery is extracted, based on this, we could combine Visualization Toolkit and Image Segmentation and Registration Toolkit with it to construct a 3D visualization system of medical images based on MRA data using C++. Results: The 3D visualization system of medical image data can be read on the MRA based on Digital Imaging and Communications in Medicine images and can be displayed completely. At the same time, a series of interactive operations can be carried out on the 3D image, and three-position blood vessel segmentation and enhancement on the basis of volume rendering can be realized. Conclusions: The medical image 3D visualization system based on MRA data can read and display 3D images and can realize a series of interactive operations, which can achieve better blood vessel enhancement effect and carotid artery extraction. It has important function and significance for a three-bit visualization of medical image.
