Most dermatologists still decide which moles require a biopsy by good old fashioned eye-balling, but a new device developed by researchers at British Colombia Cancer Agency (BCCA) could remove that guesswork, using a handheld laser to quickly identify problem spots that require closer examination.
Called the Verisante Aura, the device employsRaman spectroscopyto identify the molecular makeup of moles by changing the vibrational state of the molecular bonds in a skin growth. Shining a particular laser light on those bonds causes a shift in the kind of light that is reflected back to a sensor, and that shift belies exactly what kinds of molecules are there and in what concentration they exist.
THOUSANDS OF MEDICAL DEVICE ENGINEERS AND PROFESSIONALS CONNECTING WITH HUNDREDS OF SUPPLIERS.
Welcome to the official website for the 2011 Materials for Medical Devices Expo. This year’s event will bring over 500 suppliers to showcase their capabilities in metals, polymers, ceramics, coatings, testing, consulting and so much more to thousands of engineers in the medical device field.
Design of materials has been the hottest topic amongst medical device companies in the past 5 years. Issues such as corrosion, DEHP, BPA and many others have inspired companies to seek superior materials, coatings, and innovate the materials they use in order to provide a quality product for their customers. This expo is the biggest event to connect with highly knowledgeable suppliers of materials in order to achieve the quality needed for outstanding products.
Whenever a Biomedical Engineer goes into the field, He has to look into various matters such as What the various symbols on the machines mean. So for the convenience of all the Biomedical Engineers I am putting in the list of some commonly seen symbols.
The Berkley Tricorder is a highly integrated piece of wireless technology capable of monitoring a wide range of physiological parameters with very high precision in a compact form factor. It represents a platform that can be used for a wide range of applications such as:
Ambulatory monitoring for diagnosing health issues
Angiography or Arteriography is a medical
imaging technique used to visualize the inside, or
lumen, of blood vessels and organs of the body,
with particular interest in the arteries, veins and
the heart chambers.
“C-Arm” is a name given to
specialized X-ray imaging
machines, due to their special
arced semi-circular design. CArms
use X-rays for imaging,
but are designed to work with
lower amounts of exposure.
