Clinical translation of optical and optoacoustic imaging [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2011
Macroscopic optical imaging has rather humble technical origins; it has been mostly implemented by photographic means using appropriate filters, a light source and a camera yielding images of tissues. This approach relates to human vision and perception, and is simple to implement and use.

Optoacoustic properties of Doxorubicin - A pilot study.

PLoS ONE, 2019
Doxorubicin (DOX) is a widely used chemotherapeutic anticancer drug. Its intrinsic fluorescence properties enable investigation of tumor response, drug distribution and metabolism. First phantom studies in vitro showed optoacoustic property of DOX.

Self-Gated Respiratory Motion Rejection for Optoacoustic Tomography

Applied Sciences, 2019
Respiratory motion in living organisms is known to result in image blurring and loss of resolution, chiefly due to the lengthy acquisition times of the corresponding image acquisition methods.

[Optoacoustic spectroscopy and imaging].

Zeitschrift fur medizinische Physik, 2002
Optoacoustic methods are based on the thermoelastic effect, according to which a short laser pulse is absorbed in a medium and generates an acoustic wave following rapid heating and thermal expansion. This study it sought to demonstrate how the optical properties and structure of the sample can be obtained from acoustic signals that are measured on the

Low frequency detection in clinical multispectral optoacoustic tomography

Photoacoustics
Frequency response characterization of optoacoustic (photoacoustic) detectors is critical because the signals are broadband, and the center frequency relates to the absorber size.
