A new imaging technique creates detailed three-dimensional images of the deadliest form of skin cancer Melanoma is one of the less common types of skin cancer but it accounts for the majority of the skin cancer deaths (about 75 percent). The five-year survival rate for early stage melanoma is very high (98 percent), but the rate drops precipitously if the cancer is detected late or there is recurrence. So a great deal rides on the accuracy of the initial surgery, where the goal is to remove...

The next generation of imaging techniques could harness a technology that moves faster than the speed of light A study published in the July issue of The Journal of Nuclear Medicine (JNM) reports on investigative research of a novel optical imaging technique called "Cerenkov luminescence imaging (CLI)." According to the authors, the technique could lead to the faster and more cost-effective development of radiopharmaceuticals for the diagnosis and treatment of cancer and other conditions....

Studies use radiation luminescence and radioactive optical nano-imaging techniques indicating tumors and other disease processes During SNM's 57th Annual Meeting, investigators presented the results of a multidisciplinary study involving the capture of radiation luminescence and radioactive-excited nanoparticles to help detect subtle signs of disease. Currently, nuclear medicine agents and imaging technology image the behavior of particles at the cellular, molecular and atomic levels, but...

Ultrasound and underwater sonar devices could "see" a big improvement thanks to development of the world's first acoustic hyperlens. Created by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), the acoustic hyperlens provides an eightfold boost in the magnification power of sound-based imaging technologies. Clever physical manipulation of the imaging sound waves enables the hyperlens to resolve details smaller than one sixth the length of...

Brain cancer is among the deadliest of cancers. It's also one of the hardest to treat. Imaging results are often imprecise because brain cancers are extremely invasive. Surgeons must saw through the skull and safely remove as much of the tumor as they can. Then doctors use radiation or chemotherapy to destroy cancerous cells in the surrounding tissue.Researchers at the University of Washington have been able to illuminate brain tumors by injecting fluorescent nanoparticles into the...

Purdue University researchers have created magnetically responsive gold nanostars that may offer a new approach to biomedical imaging.The nanostars gyrate when exposed to a rotating magnetic field and can scatter light to produce a pulsating or "twinkling" effect. This twinkling allows them to stand out more clearly from noisy backgrounds like those found in biological tissue.Alexander Wei, a professor of chemistry, and Kenneth Ritchie, an associate professor of physics, led the team that...

A team of researchers at the University of Illinois has created the world's first acoustic "superlens," an innovation that could have practical implications for high-resolution ultrasound imaging, non-destructive structural testing of buildings and bridges, and novel underwater stealth technology. The team, led by Nicholas X. Fang, a professor of mechanical science and engineering at Illinois, successfully focused ultrasound waves through a flat metamaterial lens on a spot roughly half the...

New technology is giving doctors a dramatic look into patients' coronary arteries. Using a new optical imaging technique called optical frequency-domain imaging (OFDI), doctors at Massachusetts General Hospital were able to capture three-dimensional, microscopic views of patients' coronary arteries, allowing them to see areas of inflammation and plaque deposits in a whole new way. "This is the first human demonstration of a technique that has the potential to change how cardiologists look at...

Boston Micromachines Corporation, a leading provider of MEMS-based deformable mirror (DM) products for adaptive optics systems, today announced a new high speed, high precision controller for its award winning Multi-DM. With greater than 30 kHz frame rate and 14 bit resolution, the Multi-DM Controller provides a fifty fold improvement in speed and resolution over its predecessor, making it the fastest and highest resolution deformable mirror system on the market today. Also, Boston...


Word of the Day
caparison
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
  • To cover with a caparison, as a horse.
  • To dress sumptuously; adorn with rich dress.
This word ultimately comes from the Medieval Latin 'cappa,' cloak.
