The workshop's first session reviewed seismic, medical, and space imaging technology with two presentations from each field—one to introduce basic concepts and demystify the jargon, and one to describe the state of the art.

Bob Stolt's introductory seismic overview presented the basic concepts of 2- and 3D, pre- and poststack, time and depth migration, and gave simplified tutorials on different integral- and difference-equation migration techniques. “Seismic depth imaging of complex geological structures” by Larry Lines emphasized the complexity of the earth as a propagating medium, and the need for sophisticated processing to produce accurate structural images. Complex geologic structures (which...
