How is migration involved in tomography? To implement tomography successfully, a good depth image depicting the horizons (reflectors) is needed. A reliable depth image can be obtained by migration. The ideal output of tomography is a reliable velocity model. To carry out migration, a reliable velocity model is needed, and we know that such a model can be obtained with tomography. And as we already stated, the ideal output of any migration method is a reliable depth image depicting the layer interfaces (reflectors). Thus, around and around it goes, and consequently, the processes of tomography and migration can be used iteratively to produce both reliable velocity models and reliable depth images.
