Any of the available imaging techniques, such as Kirchhoff migration,
one-way wave-equation migration, or two-way reverse-time
migration can be utilized to
perform seismic imaging in image-ray coordinates using
equation 8. Moreover, staying in this coordinate system
allows migration velocity analysis and model building to be performed
for estimating the Dix velocity instead of the usual
seismic velocity
.
