Optical Fiber Sensors Enable New Biomedical Devices
Jun 1, 2022 — The biomedical community recognized the advantages of optical fibers long ago, accepting them even before their adoption for long-haul telecommunications. Early research on the light-guiding properties of fibers in the late 1920s was aimed at applications in medical imaging. The first clad optical fiber was drawn on December 8, 1956, by Larry Curtis, a graduate student under Basil Hirschowitz at the University of Michigan. The technology was used in a multifiber bundle for a fiber endoscope,...
Image Reconstruction Algorithm Improves Breast Cancer Detection
HANOVER, N.H., March 4, 2022 — Researchers from Dartmouth College, Beijing University of Technology, and the University of Birmingham have developed an image reconstruction approach that could contribute to better breast cancer detection. The approach uses a deep learning...

Global Helium Market Swings to Oversupply
HOUSTON, Nov. 8, 2016 — The global market for helium, an inert gas essential for medical resonance imaging (MRI), semiconductors, welding and other manufacturing and industrial uses, is growing at 2 percent per year. That is less than the anticipated production rate since...
Image Processing Interprets the Modern World
Jun 29, 2016 — From the moment we wake up and open our eyes, we are processing images. It is this image processing that enables us to successfully complete tasks from the mundane to those that are undertaken only by the gifted professionals trained to make...
Heat from Laser Ablation May Treat Cancer Safely, Effectively
LOS ANGELES, June 16, 2016 — A novel fusion-imaging technique uses MRI to guide the insertion of a laser fiber into a cancerous tumor. The laser, once inserted, applies heat to the cancerous tissue, destroying it. This technique, known as MRI-guided focal laser ablation, could...
Antenna-free THz Detector Uses Nanotube Thin Films
ALBUQUERQUE, N.M., HOUSTON and TOKYO, June 13, 2014 — Significant improvements in medical imaging, airport screening and food inspection could be on the horizon. A team from Sandia National Labs, in collaboration with Rice University and the Tokyo Institute of Technology, has begun developing carbon...
MRI-guided Laser an Alternative to Epilepsy Surgery
ATLANTA, June 4, 2014 — Many patients suffering from certain types of epilepsy find little relief or control by way of medications. Now there may be a new solution. A team from Emory University School of Medicine has developed an MRI-guided, minimally invasive laser...
Optical Scanner Shines New Light on Brain
ST. LOUIS, May 21, 2014 — A new generation of optical neuroimaging touts effectiveness comparable to MRI and PET technologies, but has the ability to see and study areas of the brain that the others cannot. Diffuse optical tomography (DOT) is a new brain scanning technology...
Optical Brain Monitoring for Better Stroke Care
PHILADELPHIA, March 20, 2014 — Advanced technology and simple body positioning could be key in providing acute stroke patients with more effective, individualized treatment in real time.
Replacing Mammography with Light and Ultrasound
ENSCHEDE, Netherlands, Oct. 24, 2013 — A new device called a photoacoustic mammoscope combines infrared light and ultrasound to create 3-D maps of the breast. Its creators hope that it could someday replace the x-rays used in traditional mammography for routine breast cancer screenings....
IRSC to Establish Lasers and Fiber Optics Center
FORT PIERCE, Fla., Aug. 6, 2013 — Under a $2.9 million grant from the National Science Foundation, Indian River State College (IRSC) will establish a regional center to meet a growing need for trained laser and fiber optics technicians. Workforce projections have identified a...
FAMOS aims to make OCT light sources more compact
VIENNA – Optical coherence tomography light sources will shrink to one-fifth the size of conventional devices with the help of a tapered laser being developed by the European Union project FAMOS (Functional Anatomical Molecular Optical Screening). ...

VIENNA, March 26, 2013 — Optical coherence tomography (OCT) light sources will shrink to one-fifth the size of conventional devices with the help of a tapered laser being developed by the European Union project FAMOS (Functional Anatomical Molecular Optical Screening).
Endoscope Prototype Is Small as a Human Hair
STANFORD, Calif., March 15, 2013 — Some patients dread endoscopy more than the potential diagnosis — but a new prototype is as small as a human hair. And it delivers resolution four times better than previous similar devices of similar design. The device could enable new methods in...
Laser Trapping Faux Atoms Creates ‘Super MRI’ Method
BARCELONA, Spain, Feb. 12, 2013 — A new technique, similar to the MRI but with a much higher resolution and sensitivity, uses artificial atoms to scan individual cells. The findings could revolutionize the field of medical imaging.
Light-Activated Hydrogel Repairs Cartilage
BALTIMORE, Jan. 15, 2013 — Runners and knee pain sufferers, take heed. A new squishy biomaterial called a hydrogel could help repair damaged cartilage when activated with light, giving those achy joints some relief.
NIR Imaging Gets Big Boost
STANFORD, Calif., Dec. 3, 2012 — Studying arterial diseases and therapies just got easier, thanks to a new fluorescence imaging technique that allows researchers to visualize the blood flow of living animals with unprecedented clarity. The Stanford University technique, called...
Spectroscopy Optimizes Fluorescent Probes for DNA Study
HOUSTON, Sept. 7, 2012 — Time-resolved spectroscopy plus careful calculations can optimize photoluminescent probes for studying DNA, with results nearly twice as good as standard fluorescence spectroscopy for specific sequences, according to a new paper from Rice...
Imaging Technique Pinpoints Position of Pancreatic Tumors
BERN, Switzerland, May 10, 2012 — A noninvasive way to identify the exact position of very small insulinomas — life-threatening pancreatic tumors — will allow surgeons to successfully remove growths as small as 1 cm in diameter.
Device Spots Deadly Melanoma, Cell by Cell
