Medical ultrasound usually implements ray-based imaging algorithms, in which the most severe limitation involves the implicit assumption of constant-velocity media. When there are tissues with different velocities---typical for the human body---, the

The present article outlines an innovative derivation of the well-known CRS traveltime formula. This is made possible by approximating the isochrones tangent to a small reflecting element embedded in a 3D homogeneous auxiliary medium. The arising par

In-field real-time data processing is still today a crucial factor that could definitively boost the success and spread of shallow seismic reflection and multichannel ground-penetrating radar (GPR) methods in the near-surface geoscience community, as

Prestack wave-equation migration has proved to be a very accurate shot-by-shot imaging tool. However, 3D imaging with this technique of a large field acquisition, especially one with hundreds of thousands of shots, is prohibitively costly. Simply ada

The Spectral Element Method (SEM), widely used in engineering sciences but almost unknown in Oil&Gas exploration, is a numerical technique for large scale and multi-physics simulations. SEM is an h-p approximation of the problem solution that allows

SUMMARY Although time-domain depth migration techniques have been successfully ported to run on modern hardware accelerators, their ultimate obstacle is the I/O overhead present during the imaging step. Frequency-domain depth migration algorithms ove
