Abstract :
In this paper, a method called the generalized inverse image reconstruction algorithm with threshold based on the Geselowitz sensitivity theorem is proposed, and the selection way of the regularization parameter is also presented. Both theoretical and experimental results show that this proposed algorithm can provide images superior to those obtained with filtered back-projection (FBP) and the sensitivity coefficient algorithm.
