Three-dimensional sonography (3D US) provides completely new modalities of sonographic scanning including coronar section imaging, three-dimensional reconstruction, volumetric calculations and angio-mode. Improved visualization rate, depiction of spatial relationship, "sculpture like" plastic imaging and volume measurement are the main benefits of new technology. Acceleration in scanning and re...

If singly scattered seismic waves illuminate the entirety of a subsurface structure of interest, standard methods can be applied to image it. It is generally the case, however, that with a combination of restricted acquisition geometry and imperfect velocity models, it is not possible to illuminate all structures with only singly scattered waves. We present an approach to use multiply scattered...

We apply three moveout-based methods for multiple suppression to simple synthetic common midpoint (CMP) gathers and compare their performance in terms of level of multiple rejection and, more importantly, in terms of (1) suitability of processed output for use in analysis of amplitude variations with offset (AVO), (2) primary-to-multiple amplitude (p/m) ratio of the data after CMP stacking, and...

It has been proposed that in the case of strong multiple scattering, the data matrix P is replaced by its inverse P−1 before starting seismic processing. In the inverse data space, all surface-related multiples map onto the origin, whereas the inverse of the primaries map mostly at negative times. This interesting property opens up new ways to separate primaries from multiples and apply other p...
