In this paper, we proposed a new scan mode and image reconstruction method, which combines the data from both the linear accelerator and the cone-beam CT to reconstruct the volume with a limited rotation angle and low sampling rate. The classical filtered backprojection method and the iterative method are utilized to reconstruct the volume. The reconstruction results of the two methods are compared with each other with a relavant anlysis given here.
在本文中，我们提出了一种新的扫描模式和图像重建方法，该方法结合了直线加速器和锥束CT的数据，以有限的旋转角度和低采样率重建体积。利用经典的滤波反投影法和迭代法重建体积。对这两种方法的重建结果进行了相互比较，并在此给出了相关分析。
