Optoacoustic endoscopy in curved scanning mode. [PDF]

, 2016
Optoacoustic technique has been shown to resolve anatomical, functional and molecular features at depths that go beyond the reach of epi-illumination optical microscopy offering new opportunities for endoscopic imaging.

Optoacoustic microscopy at multiple discrete frequencies. [PDF]

, 2018
Optoacoustic (photoacoustic) sensing employs illumination of transient energy and is typically implemented in the time domain using nanosecond photon pulses.

Temperature-dependent optoacoustic response and transient through zero Grüneisen parameter in optically contrasted media

Photoacoustics, 2017
Non-invasive optoacoustic mapping of temperature in tissues with low blood content can be enabled by administering external contrast agents. Some important clinical applications of such approach include temperature mapping during thermal therapies in a ...

Effect of irradiation distance on image contrast in epi-optoacoustic imaging of human volunteers [PDF]

, 2014
In combined clinical optoacoustic (OA) and ultrasound (US) imaging, epi-mode irradiation and detection integrated into one single probe offers flexible imaging of the human body.

Noncontact Liquid Crystalline Broadband Optoacoustic Sensors [PDF]

, 2022
An optoacoustic sensor includes a liquid crystal (LC) cell formed between top and bottom plates of transparent material. A transverse grating formed across the LC cell that forms an optical transmission bandgap.

Optoacoustic signal excitation with a tone-burst of short pulses

Photoacoustics, 2018
Individual light pulses with durations in the nanosecond range are most often employed in biomedical optoacoustic imaging. In this excitation regime, ultra-wideband acoustic responses are generated from tissues that cannot be efficiently captured with ...

Improving optoacoustic image quality via geometric pixel super-resolution approach. [PDF]

, 2016
High fidelity optoacoustic (photoacoustic) tomography requires dense spatial sampling of optoacoustic signals using point acoustic detectors. However, in practice, spatial resolution of the images is often limited by limited sampling either due to coarse

Phototrophic purple bacteria as optoacoustic in vivo reporters of macrophage activity

Nature Communications, 2019
Current optoacoustic probes for cancer imaging have limitations including background noise, long-term toxicity and scarce imaging depth in living tissue.
