Common midpoint versus common offset acquisition geometry in seismic imaging

We compare and contrast the qualitative nature of backprojected images obtained in seismic imaging when common offsetdata are used versus when common midpoint data are used. Our results show that the image obtained using common midpoint data contains artifacts which are not present with common offset data. Although there are situations where one would still want to use common midpoint data, this result points out a shortcoming that should be kept in mind when interpreting the images.
