      First-ever 3-D Stress Map of Developing Embryonic Heart Sheds Light on Why Defects Form

      Forces inside the beating heart of a human embryo help determine health of a baby’s heart: new 3-D images map these important forces As a human fetus develops, its heart has to keep pace with the new body’s ever-growing demands. Much of this is controlled by following genetic blueprints, but the embryonic heart also matures in response to the intense stresses of pumping blood. For the first time, researchers have been able to visualize in 3-D the stresses induced by flowing blood in an embryonic heart. The technique, which promises to provide new insight into how and why ...

      3-D Medical Scanner: New Handheld Imaging Device to Aid Doctors on the ‘Diagnostic Front Lines’

      In the operating room, surgeons can see inside the human body in real time using advanced imaging techniques, but primary care physicians, the people who are on the front lines of diagnosing illnesses, haven't commonly had access to the same technology – until now. Engineers from the University of Illinois at Urbana-Champaign (UIUC) have created a new imaging tool for primary care physicians: a handheld scanner that would enable them to image all the sites they commonly examine, and more, such as bacterial colonies in the middle ear in 3-D, or monitor the thickness and health of patients' retinas. The ...

      Cyborg Surgeon: Hand and Technology Combine in New Surgical Tool That Enables Superhuman Precision

      Even the most skilled and steady surgeons experience minute, almost imperceptible hand tremors when performing delicate tasks. Normally, these tiny motions are inconsequential, but for doctors specializing in fine-scale surgery, such as operating inside the human eye or repairing microscopic nerve fibers, freehand tremors can pose a serious risk for patients. By harnessing a specialized optical fiber sensor, a new “smart” surgical tool can compensate for this unwanted movement by making hundreds of precise position corrections each second – fast enough to keep the surgeon’s hand on target. Researchers from the Johns Hopkins University Whiting School of Engineering and Johns ...

      Tissues Tell the Tale: Non-Invasive Optical Technique Detects Cancer By Looking Under the Skin

      European researchers image blood vessels that feed skin cancer with OCT for the first time The trained eye of a dermatologist can identify many types of skin lesions, but human sight only goes so far. Now an international team of researchers has developed an advanced optics system to noninvasively map out the network of tiny blood vessels beneath the outer layer of patients’ skin, potentially revealing telltale signs of disease. Such high resolution 3-D images could one day help doctors better diagnose, monitor, and treat skin cancer and other skin conditions. The research was published today in the Optical Society ...
