Innovative Acoustic Reflection Imaging Techniques And Application To Clinical Breast Tomography
… from UST data. We have extended the planar Kirchhoff migration method used in geophysics, and combined it with sound speed and attenuation data obtained from the transmission signals to create reflection ultrasound images that are corrected for refractive and attenuative effects. </p> <p>The …

Seismic Modeling and Imaging for Detection of Clandestine Tunnels
… used the modeled seismic data to implement the Kirchhoff migration. We have investigated various types of soils and boundary conditions. The modeling and imaging can help us define the optimal seismic data acquisition scheme for detecting subsurface voids and tunnels.

Seismic Imaging of a Granitoid-Greenstone Boundary in the Paleoarchean Pilbara Craton
… section of these data were reprocessed using 2D Kirchhoff prestack depth migration to include vertical dips. The western half of the migrated section images a granitoid dome with weak to no reflectivity that extends deeper than 4 km. The eastern half images 2-3 km of layered volcanic rocks of the …
