摘要
提出了运用滤波反投影重建算法和图像缩放,构建滤波反投影成像模型,利用给出介质的接收信息,还原出探测板大小范围内的图像,从而解决CT成像系统下的参数不能直接测量的问题.
In this paper, a filtered backprojection reconstruction algorithm and image scaling are proposed toconstruct a filtered backprojection imaging model. By using the received information of the medium, the image inthe size range of the detection board is restored, so as to solve the problem that the parameters under the CT ima-ging system cannot be directly measured.
