Polarimetric measurements of terahertz scattering can detect subtle changes in tissue architecture that result from disease or damage. For example, terahertz measurements demonstrated signal contrast ...

Among the various optics-based tools used in diagnostics, diffuse optics (DO) is rapidly emerging as one of the most attractive technologies. The technique is based on analyzing how light is absorbed ...

Researchers have developed an optical biopsy system that can distinguish between cancerous and healthy liver tissue. The technology makes use of diffuse reflectance spectroscopy and lifetime ...

A fluorescence microscopy variant developed by ETH Zurich and the University of Zurich could help overcome issues of light scattering in deep-brain microangiography. As published in Optica, the ...

A new imaging technique developed by scientists at MIT, Harvard University, and Massachusetts General Hospital (MGH) aims to illuminate cellular structures in deep tissue and other dense and opaque ...

Changes in NAWM and NAGM are crucial in MS progression, challenging the traditional lesion-centric model. Subtle alterations in myelin integrity, immune cell function, and neuronal connectivity ...
