Abstract :
In this paper, a method called the generalized inverse image reconstruction algorithm with threshold based on the sensitivity theorem is proposed. The ways on which the regularization parameter is selected is also presented. Both theoretical and experimental results show that this proposed algorithm can provide images superior to those obtained with the filter back projection and the sensitivity coefficient algorithm.
