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 ...

Photoacoustic lymphangiography
Journal of Surgical Oncology, 2019AbstractBackground 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 ...

Differential absorption has been detected and localized in three‐dimensions by recording the photoacoustic pulses that were produced when short‐duration (∼1 μs) pulses of electromagnetic energy were absorbed regionally within a turbid medium. These absorption sites were localized with a spatial resolution of ∼6 mm within a 20×20×7.5‐cm3 volume of 0.3 ...

Photoacoustic spectra of MoS_2
Applied Optics, 1983The photoacoustic spectra of powdered MoS2 prepared by particle-size reduction and dilution have been determined and compared with the optical transmittance spectra of single crystals and thin-film deposits. MoS2 was chosen as a typical representative of the layer-structured transition metal dichalcogenides, for which optical properties are important ...

Photoacoustic Spectroscopy — Photoacoustic and Photothermal Effects
1990Definition. Photoacoustic (PA) or optoacoustic measurements in the original, strict sense comprise the detection of acoustic waves which arise from non-radiative de-excitation (radiationless transition) of the sample as a consequence of absorption of continuously amplitude-modulated light.
