Abstract :
A parallel formulation of the distorted Born iterative method has been presented. Such a formulation is vital to the application of multi-frequency imaging to realistic problems, since it reduces the computation time to a reasonable wait for moderately-sized problems. Numerical experiments have been presented which highlight the need for multi-frequency imaging and the benefits of parallel implementation
