In this paper a new approach to tomographic image reconstruction from projections is developed and investigated.
To solve the reconstruction problem a special neural network which resembles a Hopfield net is proposed. The reconstruction process is performed during the minimizing of the energy function in this network. To improve the performance of the reconstruction process an entropy term is incorporated into energy expression.
The approach presented in this paper significantly decreases the complexity of the reconstruction problem.
本文开发并研究了一种从投影进行断层图像重建的新方法。
为解决重建问题，提出了一种类似于霍普菲尔德网络的特殊神经网络。重建过程在该网络能量函数的最小化过程中进行。为提高重建过程的性能，在能量表达式中加入了一个熵项。
本文提出的方法显著降低了重建问题的复杂性。
