Biomedical photoacoustics in China

Photoacoustics, 2013
During the last decade, along with its explosive growth globally, biomedical photoacoustics has become a rapidly growing research field in China as well. In particular, photoacoustic tomography (PAT), capable of imaging intact biological tissue in vivo at great depths, has generated intense interest among Chinese researchers.

Deep Neural Network Application in the Phase-Match Calibration of Gas–Microphone Photoacoustics

International Journal of Thermophysics, 2020
In this paper, a methodology for the application of neural networks in phase-match calibration of gas–microphone photoacoustics in frequency domain is developed. A two-layer deep neural network is used to determine, in real-time, reliably and accurately,

Photoacoustic Imaging

2021
Photoacoustic imaging (PAI) is an emerging imaging modality that shows great potential for preclinical research and clinical practice. As a hybrid technique, PAI uniquely combines the advantages of optical excitation and of acoustic detection. Optical excitation provides a rich contrast mechanism from either endogenous or exogenous chromophores ...

Principles and advances in ultrafast photoacoustics; applications to imaging cell mechanics and to probing cell nanostructure

Photoacoustics, 2023
In this article we first present the foundations of ultrafast photoacoustics, a technique where the acoustic wavelength in play can be considerably shorter than the optical wavelength.

Photoacoustic lymphangiography

Journal of Surgical Oncology, 2019
AbstractBackground and objectivesPhotoacoustic lymphangiography, which is based on photoacoustic technology, is an optical imaging that visualizes the distribution of light absorbing tissue components like hemoglobin or melanin, as well as optical absorption contrast imaging agents like indocyanine green (ICG) in the lymphatic channels, with high ...
