Computational models of acoustic wave propagation are frequently used in transcranial ultrasound therapy, for example, to calculate the intracranial pressure field or to calculate phase delays to correct for skull distortions. To allow intercompariso

Abstract Background The epithelial-mesenchymal transition (EMT) affects the retinal pigment epithelium's natural homeostasis. According to observations from around the world, numerous oculopathies, including proliferative vitreoretinopathy (PVR), dia

Abstract Background In the pathophysiology of the retina, the epithelial–mesenchymal transition and oxidative stress play key roles. To find a relationship between oxidative stress and diabetic retinopathy or proliferative retinopathy, we used an i

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 strongly depends on physical parameters such as density, wavespeed and

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 interfaces of piecewise homogeneous domains. The discretisation of it

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 equations can be rewritten into boundary integral equations defined at the

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 higher harmonics at the focus make these problems extremely computati

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 based on high-performance computing methods are expected to form a vit

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 the nonlinearity of the system to increase, which transforms high amp

High intensity focused ultrasound (HIFU) enables highly localised, non-invasive tissue ablation, and its efficacy in the treatment of a range of cancers, including those of the kidney, prostate and breast has been demonstrated. HIFU offers the abilit
