New Surgical Tool Enables Superhuman Precision
2012-09-28 10:09:06

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...

Non-invasive Optical Technique Looks Under The Skin To Detect Cancer

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...

By combining three previously unrelated imaging tools into one new device, a team of researchers from the University of Connecticut and the University of Southern California has proposed a new way to diagnose early-stage ovarian cancer in high-risk women through minimally invasive surgery. The new technique may be better than the current standard procedure of preemptively removing the ovaries. Ovarian cancer has a low survival rate because a lack of reliable screening techniques usually...

A team of researchers from four Boston-area institutions led by Nicusor Iftimia from Physical Sciences, Inc. has demonstrated for the first time that optical coherence tomography (OCT), a high resolution optical imaging technique that works by bouncing near-infrared laser light off biological tissue, can reliably distinguish between pancreatic cysts that are low-risk and high-risk for becoming malignant. Other optical techniques often fail to provide images that are clear enough for doctors...

Optical coherence tomography technology developed by MIT team enables endoscopes to see below surface of colon, esophagus Researchers at the Massachusetts Institute of Technology (MIT) have developed a new imaging system that enables high-speed, three-dimensional (3-D) imaging of microscopic pre-cancerous changes in the esophagus or colon. The new system, described in the Optical Society's (OSA) open access journal Biomedical Optics Express, is based on an emerging technology called optical...

Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
