Photoacoustic imaging systems provide a high-resolution glimpse into the body, but they’re bulky. Now, researchers have developed a miniaturized version that fits into a watch, with hardware contained ...

Researchers developed a wearable device that can be used for non-invasive stroke risk assessment. The device uses speckle contrast optical spectroscopy to track changes in blood flow and volume in the ...

Setup of the laser speckle contrast optical spectroscopy system used to monitor scalp and brain blood flow during temporary blockage of a major scalp artery near the temple. WASHINGTON, Oct. 21, 2025 ...

Researchers have developed a laser-based device that can measure blood flow noninvasively and differentiate stroke risk based on current physiological conditions. When physicians want to know more ...

The effects of temporary mechanical circulatory support with a microaxial flow pump on mortality among patients with ST-segment elevation myocardial infarction (STEMI) complicated by cardiogenic shock ...
