The brain relies on real-time delivery of oxygen and nutrients through its microvasculature, which threads through neural ...

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 ...

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 ...

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 ...

A new imaging breakthrough combines ultrasound and light-based techniques to generate vivid 3D images that show both tissue structure and blood vessel activity. Developed by researchers at Caltech and ...

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 ...

New photoacoustic probes are allowing scientists to explore deeper into the brain as they can label and visualise neurons. Here, the scientific illustration features their novel photoacoustic dye that ...
