Imaging

  • The earlier cancer is detected, the better the odds of treating it, but tumors can be hard to spot until they get to a certain size, at which point it might be too late. Now MIT researchers have developed a new optical imaging system that could be used to spot tiny tumors deep inside the body.
  • It has been years since Google’s influential Street View left the roads and began to map everything from shopping centers to hiking trails. The device that made this happen was called the Street View Trekker, and Google just revealed an updated model.
  • A new study suggests an MRI scan can predict whether a person will develop dementia up to three years before any cognitive symptoms are detectable. It's hoped the tool will be able to better identify at-risk patients so preventative measures can be deployed to slow the onset of neurodegeneration.

    ​We already see the outside world through the windows of our home or the windshield of our car, so … why not use those things as camera lenses, instead of utilizing separate security or obstacle-avoidance cameras? Thanks to a new system created at the University of Utah, that could be a possibility.
  • If you've taken a photo in low light you've probably encountered the grainy effect that can dilute the finished product. A new AI tool could prove an incredibly easy way to remove grainy from photos, with the ability to automatically produce a clean image after analyzing only the corrupted version.
  • Medical X-ray scans have long been stuck in the black-and-white era. Now Mars Bioimaging has developed a bioimaging scanner that can produce full color, three dimensional images of bones, lipids, and soft tissue, thanks to a sensor chip developed at CERN for use in the Large Hadron Collider.
  • Researchers at Dartmouth College have developed a handheld "wand" optical tracking system which it says makes back surgery faster, safer and cheaper. Described as "a Google Maps for the body," the system provides real-time 3-dimensional tracking to help guide the surgeon as they operate.
  • Science
    ​Regular ultrasound probes have flat bases, which means they only work best when scanning objects that have similarly-flat surfaces. So, what happens if you want to inspect something that's curved or otherwise "irregular" in shape? Well, that's where a new ultrasound patch comes in.

    ​Cloudina was a tiny sea creature that existed about 545 million years ago, and many scientists believe that it played a major role in building the first reefs. Princeton geoscientists Adam Maloof and Akshay Mehra, however, think otherwise – and they do so because of a unique rock-grinding machine.
  • Science
    Researchers at MIT have developed an imaging technique that will help study exactly how electrical signals propagate through the brain, in an advance that could help us better understand Alzheimer's, epilepsy, and other brain disorders, as well as how thoughts and feelings are formed.
  • ​Imagine if doctors could see through a patient's skin, and their perspective of the underlying bones and organs changed accordingly as the person moved around. Well, that's what scientists at the University of Alberta have developed – kind of.
  • ​Eye exams may be getting quicker and easier, plus ophthalmologists may be able to save money on equipment, thanks to a new instrument developed by scientists in Poland and Spain. Unlike existing eye-examining technology, it allows the entire eye (from front to back) to be imaged via a single lens.
