Improve Kirchhoff Depth Imaging Using Full Wave Equation Traveltimes

In this paper, the authors compute traveltime-tables for Kirchhoff depth migration using a full wave equation (acoustic, visco-acoustic, elastic, visco-elastic, etc.), which can directly use high-resolution velocity models without smoothing like those derived from high-frequency reflection-FWI. The authors demonstrate with both synthetic and field data the benefits brought to Kirchhoff migration by wave equation traveltimes
