Supercomputer Simulations in Design of Ultrasound Tomography Devices

Alexander V. Goncharsky, Sergey Y. Seryozhnikov

Abstract


The paper considers the use of supercomputers in design of medical ultrasound tomography devices. The mathematical models describing the wave propagation in ultrasound tomography should take into account such physical phenomena as diffraction, multiple scattering, and so on. The inverse problem of wave tomography is posed as a coefficient inverse problem with respect to the wave propagation velocity and the absorption factor. Numerous simulations made it possible to determine the optimal parameters of an ultrasound tomograph in order to obtain a spatial resolution of 1.5 mm suitable for early-stage breast cancer diagnosis. The developed methods were tested both on model problems and on real data obtained at the experimental test bench for tomographic studies. The computations were performed on GPU devices of Lomonosov-2 supercomputer at Lomonosov Moscow State University.
