Boundary integral formulations for acoustic modelling of high-contrast media
Elwin van 't Wout, Seyyed R. Haqshenas, Pierre Gélat +2
The boundary element method is an efficient algorithm for simulating acoustic propagation through homogeneous objects embedded in free space. The conditioning of the system matrix…
Frequency-robust preconditioning of boundary integral equations for acoustic transmission
Elwin van 't Wout, Seyyed R. Haqshenas, Pierre Gélat +2
The scattering and transmission of harmonic acoustic waves at a penetrable material are commonly modelled by a set of Helmholtz equations. This system of partial differential equat…
Benchmarking preconditioned boundary integral formulations for acoustics
Elwin van 't Wout, Seyyed R. Haqshenas, Pierre Gélat +2
The boundary element method (BEM) is an efficient numerical method for simulating harmonic wave propagation. It uses boundary integral formulations of the Helmholtz equation at the…
Accelerating frequency-domain numerical methods for weakly nonlinear focused ultrasound using nested meshes
Samuel P. Groth, Pierre Gélat, Seyyed R. Haqshenas +4
The numerical simulation of weakly nonlinear ultrasound is important in treatment planning for focused ultrasound (FUS) therapies. However, the large domain sizes and generation of…
A fast full-wave solver for trans-abdominal high-intensity focused ultrasound treatment planning
S. R. Haqshenas, P. Gélat, E. van 't Wout +2
High-intensity focused ultrasound (HIFU) is a promising treatment modality for the non-invasive ablation of pathogenic tissue in many organs. Optimal treatment planning strategies…
Coupling of Wideband Impulses Generated by Granular Chains into Liquids
S. Harput, S. Freear, P. Gelat +5
An ultrasonic transducer technology to generate wideband impulses using a one-dimensional chain of spheres was previously presented. The Hertzian contact between the spheres causes…
A numerical model for the study of photoacoustic imaging of brain tumours
Kamyar Firouzi, Nader Saffari
Photoacoustic imaging has shown great promise for medical imaging, where optical energy absorption by blood haemoglobin is used as the contrast mechanism. A numerical method was de…
The effects of nonlinear wave propagation on the stability of inertial cavitation
David Sinden, Eleanor Stride, Nader Saffari
In the context of forecasting temperature and pressure fields in high-intensity focussed ultrasound, the accuracy of predictive models is critical for the safety and efficacy of tr…
