Next: PS geometry regularization Up: Rosales et al.: PS-CAM Previous: Introduction


We review the two main processes that we use to obtain PS 3-D images. The first process is PS geometry regularization, where an irregular data cube of 5 dimensions ($t, {\rm cmp}_x, {\rm cmp}_y,h_x,h_y$)is mapped into a regular mesh with 4 dimensions ($t,{\rm cmp}_x, {\rm cmp}_y,h_x,h_y=0$). The second process is PS common-azimuth migration. where we use the regular common-azimuth cube obtained using PS geometry regularization.
