Image Points are defined through geometry of sources, receivers and reflectors. IP (Image Point) transform is one type of Radon transform which change common shot section to IP domain (r-x). By the IP transform, reflection signals in time domain can be accumulated and enhanced in IP domain. We applied the IP transform to the field data of RVSP that had been carried out at the Mizunami Underground Research Laboratory (MIU) site. We could get the fault image around the MIU site using IP transform.
