摘要
提出了一种用于透射波CT中的小波卷积重建算法,并构建了离散的小波变换及CT图像重建算法,该算法在实际应用时迭代次数少、运行速度快,优于传统的Radon变换重建算法,并可利用计算机语言进行编程实现。实验结果表明,该算法在图像重建中具有运算速度快、重建图像细节准确等特点。
A convolved reconstruction arithmetic of wavelet is given that can apply to computerized tomography and construct a discrete wavelet transform and reconstruction of computerized tomography, The experimental results show that the arithmetic can be used to computer language program, In actual application, the arithmetic can be used to reconstruct tomography rapidly and iterative number is less and its benefits are more then radon transform reconstruction arithmetic.
