Abstract

We developed a new perturbation method for tomography technique. In this technique, perturbation approach is employed for calculating the Frechet derivatives. The perturbation approach is more efficient as it needs only one forward calculation for each iteration. Theoretical analysis and numerical experiments show that this method has higher stability and computing efficiency
