Photoacoustic microscopy (PAM) is used to visualize blood vessels and to monitor their time-
dependent changes. Photoplethysmography (PPG) measures hemodynamic time-series …

Functional imaging of microvascular dynamics in extremities delivers intuitive information for
early detection, diagnosis, and prognosis of vascular diseases. High-resolution and high …

Blood pulse wave velocity (PWV) is an important physiological parameter that characterizes
vascular stiffness. In this letter, we present electrocardiogram-synchronized, photoacoustic …

With a refined ultrasound-array-based real-time photoacoustic microscopy (UA-PAM)
system, we demonstrate the feasibility of noninvasive in vivo imaging of human pulsatile …

Capable of imaging blood perfusion, oxygenation, and flow simultaneously at the
microscopic level, multi-parametric photoacoustic microscopy (PAM) has quickly emerged …

Functional blood imaging can reflect tissue metabolism and organ viability, which is
important for life science and biomedical studies. However, conventional imaging modalities …

Microcirculation facilitates the blood‐tissue exchange of nutrients and regulates blood
perfusion. It is, therefore, essential in maintaining tissue health. Aberrations in …

Capitalizing on the optical absorption of hemoglobin, photoacoustic microscopy (PAM) is
uniquely capable of anatomical and functional characterization of the intact microcirculation …

We present fast functional optical-resolution photoacoustic microscopy (OR-PAM) that can
simultaneously image hemoglobin concentration, blood flow speed, and oxygen saturation …

Photoplethysmography (PPG) is a noninvasive optical technique for detecting microvascular
blood volume changes in tissues. Its ease of use, low cost and convenience make it an …
