Reconstructing multiple initial pressure and speed of sound distributions simultaneously in photoacoustic tomography [PDF]
PhotoacousticsImage reconstruction in photoacoustic tomography relies on an accurate knowledge of the speed of sound in the target. However, the speed of sound distribution is not generally known, which may result in artefacts in the reconstructed distribution of ...

Neurovascular photoacoustic tomography [PDF]
Frontiers in Neuroenergetics, 2010 Neurovascular coupling refers to the relationship between neuronal activities and downstream hemodynamic responses. Photoacoustic tomography (PAT), enabling comprehensive label-free imaging of hemodynamic activities with highly scalable penetration and spatial resolution, has great potential in the study of neurovascular coupling.

Tutorial on photoacoustic tomography [PDF]
Journal of Biomedical Optics, 2016 Photoacoustic tomography (PAT) has become one of the fastest growing fields in biomedical optics. Unlike pure optical imaging, such as confocal microscopy and two-photon microscopy, PAT employs acoustic detection to image optical absorption contrast with high-resolution deep into scattering tissue.

Feasibility and flap viability assessment of axial pattern flap harvest in a free-style manner using photoacoustic tomography [PDF]
JPRAS OpenIntroduction: An axial pattern flap is a single pedicled flap with anatomically recognized blood vessels running along its long axis, allowing it to be harvested with a considerably longer length than a random pattern flap.

Adaptive photoacoustic computed tomography
Photoacoustics, 2021 For many optical imaging modalities, image qualities are inevitably degraded by wavefront distortions caused by varying light speed. In optical microscopy and astronomy, adaptive optics (AO) has long been applied to compensate for such unwanted ...
