Researchers at the National Eye Institute in the U.S. have developed a retinal imaging technique that reveals live neurons, blood vessels, and epithelial cells within the retina. The method involves combining adaptive optics and angiography, and allows the researchers to view complex units of cells that interact in the outer edge of the retina. As this retinal region is involved in a range of diseases, including atherosclerosis, age-related macular degeneration (AMD), and Alzheimer’s disease, the researchers hope that the technique could help with diagnosis and disease monitoring. “For studying diseases,...
EyeQue, a company based in Newark, California, is releasing a vision testing system that you can use at home to test your eyes with the help of a smartphone. The EyeQue VisionCheck personal vision tracker snaps onto the screen of a smartphone and the user simply places it against the eye to perform the testing. The accompanying app displays various images on the screen and while the user looks at those, an internal motor rotates a series of lenses that work together to measure the eye's focus and astigmatism, and so...
L'Oréal, the big skin care company, has just released a tiny device for monitoring skin's exposure to the sun. Offered through Apple's online shop and at some of its physical stores, the La Roche-Posay My Skin Track UV device doesn't use any batteries while being able to upload its readings to a paired smartphone. The energy of the sun is used to store the data within the device, while near-field communication (NFC) is used to download the readings to the smartphone. Downloads are activated by simply tapping the device against the paired...
Birds and many other animals are able to perceive the Earth's magnetic field, an ability that allows them to navigate around the world with magical ease. Scientists at Helmholtz-Zentrum Dresden-Rossendorf (HZDR), a research center in Dresden, Germany, have developed an electronic skin that can give humans the same capability. The new technology may end up being used to help blind people move around their environment, and to assist those with vertigo and other orientation issues. Moreover, it may prove useful as a basis for an intuitive way to interact with computers,...
Researchers at Washington University in St. Louis have developed a diagnostic method involving photoacoustic imaging, a technique that combines ultrasound and laser light. The development may allow clinicians to diagnose ovarian cancer earlier, helping to save lives. “When ovarian cancer is detected at an early, localized stage – stage 1 or 2 – the five-year survival rate after surgery and chemotherapy is 70 to 90 percent, compared with 20 percent or less when it is diagnosed at later stages, 3 or 4,” said Quing Zhu, a researcher involved in the...
Diabetic foot ulcers are common maladies that are difficult to heal. In many cases, a total-contact cast is put on the leg with the ulcer to take the pressure off of the bottom of the foot, helping it to heal. While this is effective, supplying oxygen to the ulcer also helps it to heal. This is difficult to do when a patient wears a cast, but researchers at Purdue University have come up with a solution that just might work. The research team has developed special insoles that contain pockets...
At the just concluded American Heart Association’s Scientific Sessions 2018 in Chicago, Eko, the makers of popular digital stethoscopes, showed off a neural network AI algorithm that is able to detect murmurs better than a group of cardiologists. The study, titled "Artificial Intelligence Detects Pediatric Heart Murmurs With Cardiologist-Level Accuracy," involved teaching a computer to spot suspicious murmurs by first giving it thousands of previously diagnosed sound recordings. The computer analyzed these for unique audio signatures and found enough nuances to be able to identify murmurs in a sample auscultation. This...

Canon Medical won FDA clearance to bring to the U.S. market its brand new Vantage Orian 1.5 Tesla MRI scanner. It features a wide 71 centimeter bore and quiet operation thanks to its Pianissimo and Pianissimo Zen technologies. Pianissimo makes all scanning sequences quieter, while Pianissimo Zen allows certain scans to be performed at near ambient noise levels. To help young patients and those uncomfortable inside a scanner, Canon offers an immersive virtual experience called MR theater that combines audio and video to keep the person's attention on something other...
Mental illness can be notoriously difficult to diagnose in many cases, since symptoms may be invisible to physicians and those that are can be misleading. Objective methods that don't rely on a direct observation would help to improve diagnosis. Researchers at Draper, the famous engineering firm in Cambridge, Massachusetts, have developed a system consisting of a number of different sensors that work together to analyze various vital signs and physical parameters to help with screening, diagnosing, and monitoring mental health conditions. The sensors include headset, wrist bands, and an ankle...
It's that time of the year when we call on technological visionaries, medical futurists, and creative people of all kinds to submit medical science fiction stories to our annual Medgadget Sci-Fi Writing Contest. At Medgadget, we keep a record of the progress of medical technologies and hope to inspire you to imagine a future where medicine is able to do things that are currently deemed impossible or, even better, have not yet been imagined. Medicine, and the people that work within this field, can be influenced by new ideas and technologies, and we hope...
REVA Medical, out of San Diego, California, has released its Fantom Encore bioresorbable scaffold. The implant is made with the company's own Tyrocore polymer that is absorbed by the body over a period of time, eventually disappearing while native tissue takes over. The process helps to make sure that the lumen stays open while cells grow and rebuild the native structure of the vessel. This is the company's third generation of bioresorbable scaffolds, and it is CE Marked in Europe and available in a number of countries. The new device has thinner...
