Optical phantoms and tissue-mimicking materials have emerged as essential tools in the validation, calibration and optimisation of biomedical imaging systems. By replicating the optical and sometimes ...

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 ...

The optical field with sub-nanometer confinement can greatly enhance light-matter interactions at nanoscale (e.g., enabling forbidden atomic transitions) and push extreme optical technologies (e.g., ...

Cellular metabolism plays a critical role in various physiological and pathological processes. High resolution imaging of intracellular metabolic activities is crucial for understanding many ...

The NIH's Common Fund Advancing Non-Invasive Optical Imaging Approaches for Biological Systems Venture Initiative seeks to overcome these and other limitations through technology development that will ...
