Multiphoton Exoscope Broadens Noninvasive Imaging of Skin
Skin imaging at the cellular level is critical for understanding how diseases and aging affect the skin, and for developing strategies and therapies to prevent and combat these effects in a clinical setting. Visualizing dynamic cellular and molecular processes during the progression of skin disease and throughout the course of therapy requires an effective compact and portable imaging tool that can provide noninvasive imaging of wide (millimeter to centimeter scale) skin areas, rapid scanning and image acquisition time, submicron resolution, and label-free molecular contrast from multiple sources to enhance imaging specificity.

The Hyperspectral Camera Looks Alzheimer’s in the Eyes
Alzheimer’s disease is one of three so-called trillion-dollar diseases, along with cancer and diabetes — meaning that financial and societal costs are approaching $1 trillion worldwide. Diagnosis has historically been a complex task, requiring several specialists who perform many tests that cover an individual’s history, physical health, and cognitive performance. Following this initial analysis, more invasive and expensive tests are usually needed to make a definitive diagnosis. Recent technical developments may make this process far simpler — within the context of a simple eye examination — thanks to a combination of hyperspectral imaging, OCT, and machine learning.

Temperature-based Method May Improve Detection of Skin Cancer
An imaging technique developed by researchers at the Institut national de la recherche scientifique, can measure temperature in 2D, without contact, and in real time. The technology — single-shot photoluminescence lifetime imaging thermometry — is based on the luminescence of nanoparticles doped with rare earth ions. The method could improve photothermal therapy and help deliver early diagnoses of skin cancers.

Three-Photon Microscopy Reveals Immune Cell Behavior in Real Time
A research group from Cornell University has used three-photon microscopy to image the full depth of the popliteal lymph node in a living mouse — reportedly for the first time. The researchers successfully observed the dynamic interactions of immune cells in the lymph node in real time and at micron-scale resolution. The three-photon imaging technique for visualizing lymph nodes could provide the same level of precision for cancer biology and other biomedical research fields, according to the team.

Quantum Sensors Measure Brain Activity with Pinpoint Accuracy
Quantum sensors could be used to indicate early biomarkers for brain diseases in space and time, based on the results of a University of Sussex (England) study. Researchers showed that quantum sensors, when used with magnetoencephalography, can track changes in the brain, such as a slowdown in brain activity, spatiotemporally. In the future, the sensors could be used to scan patients periodically to check for changes in brain activity, according to the researchers.

Optical Biopsy System Cuts Potential for Misdiagnoses of Liver Cancer
An optical biopsy system that combines diffuse reflectance spectroscopy and fluorescence lifetime measurements can distinguish between cancerous and healthy tissue in the liver. The technology could make it easier to diagnose liver cancer, which is the sixth most common cancer globally. Researchers from Orel State University in Russia developed the system, which combines the two light-based techniques to evaluate markers that relate to cellular metabolism — which differs between healthy and cancerous tissue cells.

Emerging Technologies Changing Ophthalmology Access and Point of Care
Thu, Mar 17, 2022 10:00 AM - 11:00 AM EDT
This webinar — for those interested in visual optics, ophthalmology, and biomedical devices — introduces five technologies that are using optics, photonics, or imaging to redefine how patients are served along the point-of-care continuum, from diagnosis and treatment to surgical selection and correction. It also showcases how technologies are being applied to make tools more mobile and accessible, minimize workflows, and reduce the risks associated with COVID-19 to significantly improve both the patients’ and the practitioners’ experience. Presented by Luminate.
