Abstract
The present invention relates to a method of controlling the quality of seismic data that has been migrated using the generalized Radon transform, the method serving to pass between a seismic data space and a migrated image space, in which method a parameter table is calculated giving, for a seismic wave going from a point of the image to a source or a sensor, its path length, its travel time, and the angles of incidence of the wave at the beginning and at the end of the path, and in which correspondence is established between at least one zone of a first one of said two spaces and at least one zone of the second space, by using said parameter table to fill in a correspondence table QCimage.
