FDA approves AI tool for spotting wrist fractures
The FDA has been approving its fair share of AI-powered medical technology, but its latest might be particularly helpful if you ever have a nasty fall. The agency has greenlit Imagen's OsteoDetect, an AI-based diagnostic tool that can quickly detect distal radius wrist fractures. Its machine learning algorithm studies 2D X-rays for the telltale signs of fractures and marks them for closer study. It's not a replacement for doctors or clinicians, the FDA stressed -- rather, it's to improve their detection and get the right treatment that much sooner.
World's biggest CMOS sensor could help doctors detect and treat cancer
Move over, Canon, because scientists at the University of Lincoln have just seized the crown for world's biggest CMOS image sensor with their new Dynamic range Adjustable for Medical Imaging Technology microchip -- or 'DyNAMITe,' for short. Measuring a hefty 12.8 square cm (or about five square inches), DyNAMITe is roughly 200 times bigger than the chips you'd find in most PCs, making it the largest imager ever made on a wafer of standard, eight-inch diameter. This extra girth allows the active pixel sensor to capture images in high detail, with a 100-micrometer pitch boasting 1280 x 1280p aligned next to a 50-micron layer, carrying 2560 x 2560p. DyNAMITe can also run at up to 90fps and withstand high levels of radiation for several years, making it ideal for medical imaging, including radiotherapy and mammography. Researchers say these enhanced images could help doctors detect cancer in its earliest phases, while allowing them to monitor radiotherapy treatments more closely. No word on when we should expect to see DyNAMITe pop up in hospitals (or a Hasselblad back), but physicists at the Institute of Cancer Research and Royal Marsden Hospital are busy looking for other, potentially life-saving applications. Full PR after the break.
Plasma Focus researchers develop non-radioactive X-ray for metals
Cesar Moreno, who heads the "Plasma Focus" physics research group at the University of Buenos Aires, has co-developed a "non-conventional setup" for taking X-rays of metallic objects sans the need for nuclear hardware. Based on "plasma focus hard X-ray" technology, this newfangled approach differs from more traditional routes -- which require irradiating the items to be scanned with radioactive element -- by demanding only electricity and a rather large workspace. After seven years of toil (and potential exposure to incredible amounts of gene-altering radiation), he was finally able to display photos of a "camera, door lock, and a bolt fixated to a metal bar" as proof of a working machine. The device can reportedly take photographs that pass through any type of metal up to 25-millimeters thick (including moving objects) without a single "trace of radiation or heat generated during the process." Although Moreno has a lot of red tape to clear before we see his invention in radiography labs, the $10,000 prize he captured for his work should certainly provide adequate motivation to get things moving.[Via The Inquirer]
