Photoacoustic microscopy [PDF]

open access: yesLaser & Photonics Reviews, 2013
AbstractPhotoacoustic microscopy (PAM) is a hybridin vivoimaging technique that acoustically detects optical contrast via the photoacoustic effect. Unlike pure optical microscopic techniques, PAM takes advantage of the weak acoustic scattering in tissue and thus breaks through the optical diffusion limit (∼1 mm in soft tissue).

Recovery of photoacoustic images based on accurate ultrasound positioning

open access: yesVisual Computing for Industry, Biomedicine, and Art, 2021
Photoacoustic microscopy is an in vivo imaging technology based on the photoacoustic effect. It is widely used in various biomedical studies because it can provide high-resolution images while being label-free, safe, and harmless to biological tissue ...

Photoacoustic computed microscopy [PDF]

open access: yesScientific Reports, 2014
Photoacoustic microscopy (PAM) is emerging as a powerful technique for imaging microvasculature at depths beyond the ~1 mm depth limit associated with confocal microscopy, two-photon microscopy and optical coherence tomography. PAM, however, is currently qualitative in nature and cannot quantitatively measure important functional parameters including ...

Off-axis photoacoustic microscopy [PDF]

open access: yesSPIE Proceedings, 2010
Photoacoustic microscopy (PAM) is a high-contrast, high-resolution imaging modality, used primarily for imaging hemoglobin and melanin. Important applications include mapping of the microvasculature and melanoma tumor margins. We demonstrate a novel PAM design that markedly simplifies the implementation by separating the optical illumination from the ...
