Summary If the geology is complex and the rayfield becomes multi-pathed the quality of subsurface images deteriorates. To overcome this problem we perform the imaging in terms of scattering-angle and azimuth at the image point. The images are generated using an algorithm based on the inverse generalized Radon transform. Stacking only over migration dip angles we
