Time-reversal transcranial ultrasound beam focusing using a k-space method.
This paper proposes the use of a k-space method to obtain the correction for transcranial ultrasound beam focusing. Mirroring past approaches, a synthetic point source at the focal point is numerically excited, and propagated through the skull, using acoustic properties acquired from registered computed tomography of the skull being studied. The received data outside the skull contain the corre...
متن کاملTime Domain Simulation of Harmonic Ultrasound Images and Beam Patterns in 3D Using the k-space Pseudospectral Method
A k-space pseudospectral model is developed for the fast full-wave simulation of nonlinear ultrasound propagation through heterogeneous media. The model uses a novel equation of state to account for nonlinearity in addition to power law absorption. The spectral calculation of the spatial gradients enables a significant reduction in the number of required grid nodes compared to finite difference...
متن کاملSelective Acoustic Focusing Using Time-Harmonic Reversal Mirrors
A mathematical study of the focusing properties of acoustic fields obtained by a time-reversal process is presented. The case of time-harmonic waves propagating in a nondissipative medium containing sound-soft obstacles is considered. In this context, the so-called D.O.R.T. method (decomposition of the time-reversal operator in French) was recently proposed to achieve selective focusing by comp...
متن کاملSubwavelength focusing in bubbly media using broadband time reversal
Thanks to a multiple-scattering theory algorithm, we present a way to focus energy at the deep subwavelength scale, from the far field, inside a cubic disordered bubble cloud by using broadband time reversal (TR). We show that the analytical calculation of an effective wavenumber performing the independant scattering approximation (ISA) matches the numerical results for the focal extension. Sub...
متن کاملSubwavelength dynamic focusing in plasmonic nanostructures using time reversal
We employ time reversal for deep subwavelength focusing in plasmonic periodic nanostructures. The strong anisotropy enables propagating modes with very large transverse wave vector and moderate propagation constant, facilitating transformation of diffraction-limited plane waves to high-K Bloch waves in the plasmonic nanostructure. Time reversal is used to excite the waves in the nanostructure a...
