Theoretical and experimental aspects of two-dimensional (2D) biomedical photoacoustic
imaging have been investigated. A 2D Fourier-transform-based reconstruction algorithm that …

Biomedical photoacoustic tomography (PAT) is a soft-tissue imaging modality which
combines the high spatial resolution of ultrasound (US) with the contrast and spectroscopic …

Biomedical applications of photoacoustics, in particular photoacoustic tomography, require
efficient models of photoacoustic propagation that can incorporate realistic properties of soft …

Several different reconstruction algorithms have been proposed for photoacoustic
tomography, most of which presuppose that the acoustic properties of the medium are …

The ultimate goal of photoacoustic tomography is to accurately map the absorption
coefficient throughout the imaged tissue. Most studies either assume that acoustic properties …

We report on experimental demonstration of photoacoustic tomography for reconstructing
the optical absorption coefficient images of heterogeneous media. Photoacoustic images …

Quantitative imaging of optical properties of biological tissues with high resolution has been
a long-sought-after goal of many research groups. Photoacoustic imaging is a hybrid bio …

Existing approaches to image reconstruction in photoacoustic computed tomography
(PACT) with acoustically heterogeneous media are limited to weakly varying media, are …

Photoacoustic tomography (PAT), also known as thermoacoustic or optoacoustic
tomography, is a rapidly emerging imaging technique that holds great promise for …

We present here an expression for the photoacoustic contribution of an optical point source
in a diffusive and absorbing medium. By using this measurement as a reference, we present …
