摘要
提出了一种利用兆伏级直线加速器所具有的一定的成像功能,联合锥束CT,在旋转角度小和低采样率的情况下,进行图像重建的方法。还比较了经典的滤波反投影算法和迭代重建算法两种重建结果,并给出了相应的分析。
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.
