Fatty Liver Disease Diagnosis With Hyperspectral Imaging

Researchers have demonstrated that X-Ray Holographic Nano-Tomography (XNH) could help accelerate efforts to map neural circuits and ultimately the brain itself. The team describes how XNH can be used to image relatively large volumes of mouse brain and fruit fly nervous tissue at high resolutions. Combined with artificial intelligence-driven image analysis, they reconstructed dense neural [..]

While your skeleton helps your body to move, fine skeleton-like filaments within your cells likewise help cellular structures to move. Now, researchers have developed a new imaging method that lets them monitor a small subset of these filaments, called actin. Actin is the most abundant protein in the cell, so when you image it, it’s [..]

Researchers have demonstrated that a new mapping approach based on near-infrared spectroscopy can distinguish between fat and muscle tissue in the heart. This distinction is critical when using radiofrequency ablation to treat a serious heart rhythm problem known as ventricular tachycardia. Radiofrequency ablation, the only treatment for ventricular tachycardia, involves identifying areas of the heart [..]

Fatty Liver Disease Diagnosis With Hyperspectral Imaging

The tree of life is rich in examples of species that changed from living in water to a land-based existence. Occasionally, some species took the opposite direction. New insights, provided by a CT scan, into the anatomy of the inner ear of prehistoric reptiles, the thalattosuchians, revealed details about one of these evolutionary turning points. [..]

Silver Nanocubes can make diagnostic tests that rely on fluorescence easier to read by making them more than 150 times brighter. Combined with an emerging point-of-care diagnostic platform already shown capable of detecting small traces of viruses and other biomarkers, the approach could allow such tests to become much cheaper and more widespread. Plasmonics is [..]

The number of COVID-19 cases has not yet hit its peak and supplies of essential personal protective equipment (PPE) such as N95 masks are dwindling, so medical communities are desperately looking for alternative solutions for disinfecting masks that healthcare workers are being forced to reuse. Medical optics solutions can prove very helpful in such conditions.  [..]

Phase Contrast Imaging

Propagation-based phase-contrast CT (PB-CT) is an advanced X-ray imaging technology that can generate higher quality diagnostic breast images than absorption-based CT (AB-CT), at a glandular radiation dose comparable to, or lower than, conventional mammography and digital breast tomosynthesis (DBT). The technology is currently limited to use with synchrotron light sources, but the evolution of compact [..]

Lasers that switch on and off billions of times per second are the backbone of optical communications networks, but this feat is only possible at certain laser frequencies. A team of researchers has now taken a step towards extending this frequency range by using sound waves to modulate the emission of a terahertz (THz) quantum [..]
