Chapter 7
Prestack Migration Examples

This chapter is devoted to assessing the quality and usability of a wide variety of prestack imaging algorithms. Visual side-by-side comparisons provide ample empirical evidence to conclude that the more accurate the algorithm, the wider the aperture, and the more careful the application, the better the result. Ultimately, we will argue that the full two-way method is by far the best at providing optimum imaging. When computational expense is not an issue, this should definitely be the method of choice.

The images in this chapter are self-explanatory and require little or no real attention to visual detail. Because they are so small, it is better to see them on the screen.
