Conventional wave equation migration is performed by propagating data downward through a velocity model into the earth and is limited where the structure and velocity field generate more complex arrivals, such as turning and 'prism' waves. Complex propagation paths give rise to arrivals that are seen as noise in the imaged data.
RTM propagates events both downward and upward through the earth model, explicitly handling turning waves and all other complex propagation paths. In many cases the ability to make use of these complex wave modes allows imaging of parts of the subsurface that otherwise have poor direct illumination.
