  journal={arXiv: Computational Physics},
We present numerical simulations for modelling optoacoustic (OA) signals observed in PVA hydrogel tissue phantoms. We review the computational approach to model the underlying mechanisms, i.e. optical absorption of laser energy and acoustic propagation of mechanical stress, geared towards experiments that involve absorbing media only. We apply the numerical procedure to model signals observed in the acoustic near- and farfield in both, forward and backward detection mode, in PVA hydrogel tissue…

Numerical prediction of the piezoelectric transducer response in the acoustic nearfield using a one-dimensional electromechanical finite difference approach

We present a simple electromechanical finite difference model to study the response of a piezoelectric polyvinylidenflourid (PVDF) transducer to optoacoustic (OA) pressure waves in the acoustic



Tissue phantoms for multimodal approaches: Raman spectroscopy and optoacoustics

A hydrogel phantom that was created for combined Raman spectroscopic and optoacoustic measurements imposing optical as well as acoustic requirements on the phantom is presented.

Pulsed optoacoustic characterization of layered media

Thermoelastic waves generated by absorption of short laser pulses are used to characterize the layer structure of materials. The method is based on the analysis of the distribution of absorbed laser

Time-resolved laser optoacoustic tomography of inhomogeneous media

The methods of time-resolved laser optoacoustic tomography of inhomogeneous media and related problems are reviewed. Time-resolved laser optoacoustic tomography allows one to measure the distribution

Acoustical properties of selected tissue phantom materials for ultrasound imaging

The characterization of the acoustic properties of four materials intended for the development of tissue, and especially breast tissue, phantoms for the use in photoacoustic and ultrasound imaging are summarized.

Diffraction-free acoustic detection for optoacoustic depth profiling of tissue using an optically transparent polyvinylidene fluoride pressure transducer operated in backward and forward mode.

An optoacoustic detection method suitable for depth profiling of optical absorption of layered or continuously varying tissue structures is presented, which allows reconstruction of optical properties of the sample to a depth of several millimeters with a spatial resolution of 24 mum.

Efficient polar convolution based on the discrete Fourier-Bessel transform for application in computational biophotonics

We discuss efficient algorithms for the accurate forward and reverse evaluation of the discrete Fourier-Bessel transform (dFBT) as numerical tools to assist in the 2D polar convolution of two

Poly(vinyl alcohol) gels as photoacoustic breast phantoms revisited.

Large PVA samples prepared using the standard recipe make excellent breast tissue phantoms, and the phantom's reduced scattering spatial distribution matches the optical properties of the standard two-layer breast model used in x ray dosimetry.
