Melanin matters: (A–C) Forearms of volunteers with different skin tones (Fitzpatrick scale 1, 4 and 6); the blue line is the imaging plane. (D–F) Photoacoustic (PA) and ultrasound overlays show higher ...

The use of wavefront shaping to compensate for scattering has brought a renewed interest as a potential solution to imaging through scattering walls. A key to the practicality of any imaging through ...

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 an imaging modality related to ultrasound imaging. A light source is inserted into a hollow-core needle and used to illuminate the patient's tissues. The tissue expands, ...

In the last decade, photoacoustic tomography has slowly emerged as a versatile, radiation-free imaging modality that bears great potentials for basic research and clinical diagnostic applications. Its ...

Researchers have demonstrated a new endoscope that uniquely combines photoacoustic and fluorescent imaging in a device about the thickness of a human hair. The device could one day provide new ...

In life sciences, confocal fluorescence microscopy (CFM) is widely regarded for producing high-resolution cellular images. However, it requires fluorescent staining, which poses risks of ...

A new non-invasive technique has been proposed to examine deep into the body using light. Photoacoustic imaging – which allows us to see inside the body using ultrasound generated when a laser is ...

Traditional medical imaging – used to diagnose, monitor or treat certain medical conditions – has long struggled to get clear pictures of patients with dark skin, according to experts. Researchers say ...

Optical-resolution photoacoustic microscopy: Maximum amplitude projection (MAP) images of the mouse-ear, close-up views of the regions in the green dashed boxes, and cross-sectional B-mode images of ...

Both for research and medical purposes, researchers have spent decades pushing the limits of microscopy to produce ever deeper and sharper images of brain activity, not only in the cortex but also in ...
