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

In this article the Marchenko integral equations leading to the solution of the inverse scattering problem for the 1-D Schrodinger equation on the line are solved numerically. The linear system obtained by discretization has a structured matrix which

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

We show over 200x speedup of our proprietary data intensive application, 3D-ZO-CRS, utilizing a FPGA-based solution, compared to conventional x86_64 CPU cores. As well as performance a second, but no less important, target was to maintain the portabi
