摘要
以平行射束扫描的 X射线 CT为例 ,提出一种运用 Hopfield人工神经元网络实现从投影中重建图象的方法 .首先将图象重建问题转化为最小范数准则下的优化问题 ,然后构造相应的 Hopfield神经网络模型 ,网络的稳态解 ,即为重建问题的解 。
In this paper,a method ofimage reconstruction from projections with a neural network is presented. The Problem of image reconstruction is formulated as opti- mization under the criterion of minimum norm. A Hopfield network is then constructed to solve the optimization problem.
