摘　　要：医学图像的三维重建对手术计划起着至关重要的作用。传统的MC算法由于构成等值面的三角面片的位置与方向容易受体数据场的噪声影响,得到的三维显示图像可视性较差,且绘制时间过长,不能满足医学应用所要求的重建效果和交互速度。利用计算机图形学进行几何模拟,通过调用OPENGL的扩展库进行血管的三维表面绘制,得到相对MC算法得出的图像更为平滑的三维血管图像。Three-dimensional reconstruction of medical images plays a vital role in surgical planning. Because the place and direction of the triangle mesh are easily affected by noise in large volumes of data, the results from a conventional MC algorithm produce poor visibility and cost too much time, and therefore not meet the requirements of medical applications. In this paper, we use computer graphics technology to simulate the blood vessels of the liver, using the QPENGL library to draw three-dimensional blood vessels, from which we can obtain smooth three-dimensional blood vessel images.
