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 ...

Differential quartz-enhanced photoacoustic spectroscopy
Applied Physics Letters, 2023In this paper, a differential quartz-enhanced photoacoustic spectroscopy (D-QEPAS) sensor is reported. The differential photoacoustic cell (PAC) was used to generate the photoacoustic effect. Two quartz tuning forks (QTFs) with a quality factor (Q) up to

The culprits of atherosclerosis are endothelial damage, local disorders of lipid metabolism, and progressive inflammation. Early atherosclerosis is typically difficult to diagnose in time due to the lack of obvious symptoms, thus missing the best period ...

Optical imaging plays a crucial role in biomedicine. However, due to strong light scattering and autofluorescence in biological tissue ranging 650-900 nm, conventional optical imaging often has poor signal-to-background ratio and shallow penetration ...

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 ...
