Design And Implementation Of Medical Image3d Visualization Platform Based On OpenGL

With the development of computer graphics technology, the demand for three-dimensional information is increasing. With the rapid development of three-dimensional visualization technology, the effect and influence that medical image processing technology use on medical research and clinical practice is increasing. The results of three-dimensional imaging make clinicians to observe of the lesion within the human body more direct and clear, thus greatly improving the efficiency and accuracy that clinicians diagnosis the conditions of patients. Therefore, medical image processing technology has been highly valued domestic and foreign experts.In this paper, three-dimensional visualization technology in both surface rendering and volume rendering algorithms and their optimization are introduced, through OpenGL, MITK class library and MFC, we describe the implement of two algorithms and contrast the results of these algorithm.In this paper, the implementation of platform is based on OpenGL, MITK class library, MFC technology to complete. OpenGL is easy to use and high efficiency, which is a recently developed three-dimensional graphics performance standards. It is initiated by the SGI and many other world-famous computer companies and a common shared and open three-dimensional graphics standard based on SGI’s GL three-dimensional graphics library; MITK is a medical image processing and analysis of C++class library, with a flexible interface and many efficient rendering algorithms. MFC (Microsoft Foundation Classes) is similar with VCL, which is an Application Framework. The library provides a set of generic and reusable class library for developers. MFC is used for writing applications under a framework and engine in C++environment. MFC is not only a simple interface development system, but also provides most of the classes used to interface development, associating with a window action. Through the above techniques and methods, the platform will implement function that CT, MRI and other equipment capture two-dimensional image into three-dimensional image, simultaneously achieving interactive features three-dimensional image rotation, stretching, movement and color up, allowing doctors to observe the results of imaging. Doctors are allowed to use the platform to generate the results of three-dimensional imaging, improving efficiency and diagnostic accuracy of doctors.
