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 ...

A newly developed imaging method blends ultrasound and photoacoustics to capture both tissue structure and blood-vessel function in 3D.

In a proof-of-concept study, researchers from the Keck School of Medicine of USC and the California Institute of Technology (Caltech) have shown that an innovative, noninvasive technique can be used ...

For decades, scientists have worked to peer deeper into the brain. They have wanted to see not just surface activity in the cortex but also the hidden layers beneath, such as the hippocampus, where ...

In a recent study published in the journal Nature Biomedical Engineering, researchers developed a three-dimensional (3D) photoacoustic tomography (PAT) scanner for rapid vascular imaging. Visualizing ...

Optical-resolution photoacoustic microscopy is an up-and-coming biomedical imaging technique for studying a broad range of diseases, such as cancer, diabetes and stroke. But its insufficient ...

Photoacoustic imaging is a technique that merges the high spatial resolution of optical imaging with the deep tissue penetration of ultrasound. This hybrid approach has garnered significant interest ...

Neuroscientists have sought to better understand brain function but lacked the capability to observe neuronal activity deep within the brain. Scientists have applied rational molecular engineering to ...

In a new study, researchers show, for the first time, that photoacoustic microscopy can image stents through skin, potentially offering a safer, easier way to monitor these life-saving devices. Each ...
