Large-scale microscopy combined with tissue clearing and expansion enables nanoscale imaging of centimeter scale specimens.

Methods: A total of 32 RA patients received PA/US examination on seven small joints (MCP2, MCP3, PIP2, PIP3, MTP2, MTP5, and wrist of the clinically dominant side). The 0-3 score was used to ...

A project at Brown University and Morgan State University has now demonstrated a smartphone-based skin-assessment imaging ...

The articles in this special section focus on the technology and biomedical applications supported by photoacoustic imaging. In today’s clinical practice, human vision remains the major diagnostic ...

Photoacoustic imaging (PAI), renowned for its high spatial resolution and deep tissue penetration, holds great promise for disease diagnosis and molecular detection. However, the performance of ...

We developed an automated photoacoustic and ultrasound breast tomography system that images the patient in the standing pose. The system, named OneTouch-PAT, utilized linear transducer arrays with ...

Rapid detection of hydrogen (H2) is essential for industrial production and environmental monitoring. Beat frequency photoacoustic spectroscopy offers an inherent measurement speed of milliseconds but ...

Serious hidden hypoxemia — defined as an SaO2 less than 88% despite an SpO2 of 92% or greater — occurred in 0.6% of the critically ill Asian patients studied. Hypoxemia went undetected in 0.8% of ...
