Two-pass prestack depth imaging

The two-pass prestack method consists of cross-line prestack time migration of 3-D data followed by in-line 2-D prestack depth migration. This form of the idea was originally proposed by Gerry Gardner when he was a Rice University professor and a principle investigator in the HARC/GTRI 3D Imaging Consortium.

I still believe depth imaging geophysicists could benefit by having two-pass depth imaging capabilities on their workstations for reconnaissance imaging and model testing purposes.

Unfortunately, I don't think this idea ever caught on.
