摘　　要：本文报道作者开发研究的医学图象处理系统Ｖｉｓｕａｌｉｚｅｒ的系统结构及各功能模块的实现方法。在医学图象三维显示上，首次提出一种以斜单元模型代替以往的立方体单元模型的体视算法，这种新的显示算法运行速度快，同时又能产生高质量的显示图象。最后，本文以人脑部磁共振图象的操作和显示实例来说明系统的实用性和算法的有效性。We introduced the structure of medical image processing system Visualizer and its functional modules. A novel rendering algorithm using oblique cell models instead of conventional cubic ones was proposed which significantly improved rendition speed without lost of rendered image qualities. Finally, we gave examples manipulating and rendering MR images of human head to demonstrate the usefulness and advantages of our algorithm.
