** Previous:** CONCLUSIONS

The parameters used in GB computation and the maximum number of rays
needed to approximate a point source wavefield should be interrelated.
Future research should determine these parameters for efficient
computation.
In addition, more work is needed to demonstrate the application of Gaussian
beams to image complex geological models, such as salt domes.
And in general, more work is
needed to realize the wide potential of prestack Gaussian beam migration.
