Abstract


3D medical image reconstruction is a multi -disciplinary field of study ; the use of computer graphics , image processing , computer vision , and human-computer interaction technology , medical image data is converted to graphics or images displayed on the screen , and interactive processing theory , methods and techniques ; has important applications in biomedical engineering . This paper studies the implementation of cross-platform 3D medical image reconstruction system . On the basis of research on the three-dimensional reconstruction techniques , combined with visualization tools, VTK (Visualization Toolkit) and medical image segmentation and with quasi - tools package ITK ( Insight Segmentation and the Registration Toolkit ) and graphical user interface ( GUI ) tools package QT , the use of large scale design patterns in software engineering ideas, design and implementation of a medical image processing system MRS . It is an object-oriented , scalable system , the integration of several different types of open source , and add an extension for the specific application . The article also studies compared different three-dimensional visualization algorithm , and accurate measurement based on 3D segmentation . Three-dimensional visualization algorithm is divided into two categories: surface rendering and direct volume rendering . The surface rendering object isosurface extracted from the 3D volume data , by traditional graphics display ; volume rendering technology will be the entire data field is visualized as a whole , so that doctors can be more intuitive to observe the three-dimensional internal structure of the medical data . This paper describes the the body rendering algorithm based on texture mapping , ray casting volume rendering algorithm , Marching cubes surface rendering algorithm implementation mechanism and scope of application . The traditional three-dimensional measurement , this paper presents an improved measurement methods . Introduction of a Z axis perpendicular to the cutting plane , this plane locking measured at the three-dimensional depth information ; introduced into the measurement buffer at the same time to improve the measurement speed ; using three - dimensional cutting and three-dimensional rotation to achieve precise three-dimensional measurement .
