Numerically and experimentally investigate the dispersion properties of leaky Lamb waves in the cranial bone and show that, when diploic pores are physically modeled, leakage angles computed from time transient finite-element analyses correspond to those predicted by an equivalent three-layered fluid-loaded waveguide model.

Prediction and near-field observation of skull-guided acoustic waves
- PhysicsPhysics in medicine and biology
- 2017
The existence of skull-guided acoustic waves was reported on and confirmed by near-field measurements of optoacoustically-induced responses in ex-vivo murine skulls immersed in water, andersion of the guided waves was found to reasonably agree with the prediction of a multilayered flat plate model.

It is anticipated that accurate quantification and modeling of the skull transmission effects would ultimately allow for skull aberration correction in a broad variety of applications employing transcranial detection or transmission of high frequency ultrasound.
Treatment of near-skull brain tissue with a focused device using shear-mode conversion: a numerical study
- Physics, MedicinePhysics in medicine and biology
- 2007
Shear waves provide a useful method for trans-cranial focusing in regions close to the skull surface and the differences of the degree of focusing observed among patients suggest that the intersection ASW∩ATX can be used as a preliminary criterion for screening and calculation of the acoustic fields should confirm thedegree of focusing patient by patient.

It is concluded that with selection of appropriate frequencies (0.5-1.0 MHz) and beam configuration it will be possible to perform clinically significant transkull diagnostic imaging and interrogation in the adult human brain.
Attenuation, scattering, and absorption of ultrasound in the skull bone.
- PhysicsMedical physics
- 2012
This first measurement of ultrasound absorption in bone can be used to estimate the amount of heat deposition based on knowledge of the acoustic field and it is demonstrated that only a small part of the attenuation is due to absorption inBone and that the majority of the dBs are due to reflection, scattering, and mode conversion.

It is shown that strong low-pass filtering characteristics of the skull may significantly deteriorate the achievable spatial resolution in deep brain imaging where no light focusing is possible and significant improvements are seen through cranial windows and thinned skull experiments.
