Fraunhofer ITWM and Statoil have developed an angle domain migration based on the theory of generalized Radon transform (GRT) for massively parallel commodity clusters (Ettrich, N., Merten, D. and Foss, S.-K., 2008. True-amplitude Angle Migration in Complex Media, EAGE, Expanded Abstracts).

The underlying technology of ITWM's GPI allows to efficiently handle big data sets in memory as needed for GRT migration jobs with acceptable turn-around time. ITWM's GRT is worldwide among the very few implementations of this method that run in production-mode on big data sets.
