Based on the RTH-approach we can design a new voxel-based classification of all seismic  imaging methods.  From the point of view of the mechanism for creating seismic images, the RTH method has a fundamental difference from all previous methods of time and depth migration, such as Kirchhoff migration, PSTM, PSDM, RTM, CSPD, etc.

This difference is concluded in other — statistical  principles of   imaging of scattering medium.

The new voxel-based classification of the seismic  imaging methods is based on the next principals:

• If a method operates only with amplitude of wave for image of properties at each voxel of  medium, then it can be called scalar-based method (PSDM, PSTM, CSPD, etc.).
• If a method uses both amplitude and phase of acoustic wave, then these method can be called vector-based method (RTH) and finally,
• if a method uses tensor information of elastic medium, then this type of seismic imaging method can be called tensor-based method (Tensor Reverse Time Holography — TRTH).
