Review on practical photoacoustic microscopy

open access: yesPhotoacoustics, 2019
Photoacoustic imaging (PAI) has many interesting advantages, such as deep imaging depth, high image resolution, and high contrast to intrinsic and extrinsic chromophores, enabling morphological, functional, and molecular imaging of living subjects ...

Optical and mechanical properties in photorefractive crystal based ultrasound-modulated optical tomography [PDF]

open access: yes, 2006
Ultrasound-modulated optical tomography (UOT) is a new technique that combines laser light and ultrasound to provide images with good optical contrast and good ultrasound resolution in soft biological tissue.

Toward functional ultrasound-modulated optical tomography: a phantom study [PDF]

open access: yes, 2008
We present the feasibility of functional ultrasound-modulated optical tomography (UOT) in tissue phantoms with two optical wavelengths. By using intense acoustic bursts and a CCD camera-based speckle contrast detection technique, we observe variations of

Fundamental considerations for multiwavelength photoacoustic molecular imaging [PDF]

open access: yes, 2006
Photoacoustic technology offers great promise for molecular imaging in vivo since it offers significant penetration, and optical contrast with ultrasonic spatial resolution.

Signal processing in microwave-induced thermoacoustic tomography [PDF]

open access: yes, 2001
Microwave-induced thermoacoustic tomography was explored to image biological tissues. Short microwave pulses irradiated tissues to generate acoustic waves by thermoelastic expansion. The microwave-induced thermoacoustic waves were detected with a focused

Photoacoustic Doppler flowmetry [PDF]

open access: yes, 2008
We report flow measurements based on the photoacoustic Doppler effect. We have performed flow experiments with a suspension of micrometer carbon particles and have detected the photoacoustic Doppler shift at various average flow speeds.

Detection, numerical simulation and approximate inversion of optoacoustic signals generated in multi-layered PVA hydrogel based tissue phantoms

open access: yesPhotoacoustics, 2016
Optoacoustic (OA) measurements can not only be used for imaging purposes but as a more general tool to “sense” physical characteristics of biological tissue, such as geometric features and intrinsic optical properties.

In vivo functional photoacoustic imaging of brain tumor vasculature [PDF]

open access: yes, 2006
We present a study of the functional photoacoustic imaging of tumor hypoxia in mice in vivo. Based on spectroscopic photoacoustic tomography that detects the optical absorption of oxy- and deoxy-hemoglobins, the blood oxygen saturation and the ...
