Laser-based camera improves view of the carotid artery

Ann Arbor: Michigan Medicine researchers employ novel technology to monitor vulnerabilities for cardiovascular events, aid in diagnosis and treatment.. Strokes and heart attacks often strike without warning. But, a unique application of a medical camera could one day help physicians know who is at risk for a cardiovascular event by providing a better view of potential problem areas.A new paper in Nature Biomedical Engineering (link is external) reports proof-of-concept results for this new imaging platform for atherosclerosis.

New Visual Symptoms Following LASIK Surgery

JAMA: In a study published online by JAMA Ophthalmology, Malvina Eydelman, M.D., of the U.S. Food and Drug Administration, Silver Spring, Md., and colleagues examined the frequency of patient-reported visual symptoms, dry eye symptoms, satisfaction with vision, and satisfaction with laser insitu keratomileusis (LASIK) surgery in the Patien

First Liquid Nanolaser Technology could lead to new way of doing ‘lab on a chip’ medical diagnostics

Northwestern University scientists have developed the first liquid nanoscale laser. And it’s tunable in real time, meaning you can quickly and simply produce different colors, a unique and useful feature. The laser technology could lead to practical applications, such as a new form of a “lab on a chip” for medical diagnostics. To understand the concept, imagine a laser pointer whose color can be changed simply by changing the liquid inside it, instead of needing a different laser pointer for every desired color. In addition to changing color in real time, the liquid nanolaser has additional advantages over other nanolasers: it is simple to make, inexpensive to produce and operates at room temperature.
