摘　　要：为了提高DividingCubes算法的绘制速度,结合螺旋CT扫描数据的特点,提出了一种改进的快速三维表面绘制方法。通过利用体元的特点和体元间的相互关系,对体元进行了特殊的处理,大大提高了三维重建的速度。In accordance with the characteristics of the data of spiral CT scanning,an improved algorithm for construction on threedimensional surface based on Dividing Cubes is proposed in order to accelerate the speed. Compensated treatment is introduced for the cube by using the characteristics of the cube and the relationship between the cubes, the efficiency of the calculation has been improved noticeably. 
