Shortwave IR Imaging Aids in Tumor Identification
LONDON, March 30, 2023 — A method combining highly detailed, real-time images within the body with shortwave infrared (SWIR) light has been used for the first time during surgery to differentiate cancerous tumors and healthy tissue. The technique, which was already demonstrated in mice, was developed by engineers at the Wellcome/EPSRC Centre for Interventional and Surgical Sciences (WEISS) at University College London (UCL) and surgeons at Great Ormond Street Hospital (GOSH). SWIR imaging holds advantages
Project to Use Quantum Imaging to Track the Pathology of Tumors
DARMSTADT, Germany, Feb.16, 2023 — A project funded by the German Federal Ministry of Education and Research will investigate the viability of quantum optical imaging for tumor diagnostics. Nine project partners, including TU Darmstadt, will explore the issue in the €6.7 million...
Photoacoustic Approach Improves on Detection Sensitivity
SHENZHEN, China, March 8, 2022 — Researchers at the Shenzhen Institute of Advanced Technology (SIAT) achieved deep, tumor-targeted, photoacoustic imaging without losing signal intensity or resolution. To control interference from background signals, they developed a reporter...
Machine Learning-Enabled NIR Hyperspectral Imaging System IDs Hidden Tumors
TOKYO, Feb. 5, 2021 — Collaborating researchers from Tokyo University of Science, National Cancer Center Hospital East, and RIKEN Center for Advanced Photonics have developed a technology using near-infrared hyperspectral imaging (NIR-HIS) and machine learning that finds...
Light-Sheet Microscopy Method Improves Cancer Diagnostics
VIENNA, Oct. 30, 2020 — A microscopy technique developed by researchers at TU Wien (Austria) in collaboration with TU Munich could lead to more reliable cancer diagnostics. The technique allows a tumor to be analyzed after surgery in 3D without cutting the tumor into...
Applications Expand for Photon Counting
Oct 3, 2014 — The prospects of photon-counting imaging are as diverse as they are promising. From space-debris monitoring, to telecommunication satellites and shuttle missions, to the advent of powerful surgical tools, which could help cancer patients through the...
Photoacoustic Device Enables In Vivo Melanoma Imaging
ST. LOUIS, Aug. 8, 2014 — A new device could help doctors better diagnose and treat melanoma, one of the deadliest forms of skin cancer. A team from Washington University in St. Louis developed a handheld instrument that uses lasers and sound waves. Used directly on a...
High-Tech Glasses Show Cancer Cells
ST. LOUIS, March 14, 2014 — Distinguishing between cancer cells and healthy cells could become easier for surgeons. And all they'll need to do is put on glasses.
Needle Microscope Wins SPIE Startup Challenge
CRAWLEY, Australia, and BELLINGHAM, Wash., Feb. 14, 2014 — A new needle microscope that will assist in breast cancer treatment has earned SPIE’s annual Startup Challenge. The “Microscope in a Needle” project, developed by a team from western Australia and led by Robert McLaughlin, an...
Laser Process Shows Promise for Skin Cancer Treatment
CAMBRIDGE, Mass., Feb. 7, 2014 — The treatment of basal-cell carcinoma (BCC) with a new combination of lasers – pulsed dye and Nd:YAG – has yielded some good results, offering the potential for nonsurgical treatment.
Multispectral Camera Detects Tumors During Surgery
MANNHEIM, Germany, Nov. 11, 2013 — A multispectral camera that simultaneously displays several fluorescent dyes and the reflectance image in real time could help surgeons ensure that they don’t leave behind tiny pieces of malignant tumors. Obviously, cancer patients have a...
Photons vs. Protons in Radiation Therapy
COLUMBUS, Ohio, Jan. 13, 2011 — A study comparing the long-term outcomes of patients with spinal-cord tumors after radiation therapy suggests that certain subsets of patients have better long-term survival. It also suggests that photon-based radiation therapy may result in better...
Lung Cancer Detection Gets Cheeky
EVANSTON, Ill., Nov. 16, 2010 — Using pioneering biophotonics technology, researchers at Northwestern University and NorthShore University HealthSystem (NorthShore) have developed a method to detect early signs of lung cancer by examining cheek cells in humans. “By...
GE Awarded $4M NIH Grant
NISKAYUNA, N.Y., June 14, 2010 — Researchers from GE Global Research were awarded a four-year, $4 million grant from the National Institutes of Health (NIH) to optimize a nerve labeling agent and imaging system. Cristina Tan Hehir, GE biochemist and project leader on the...
Igniting a few good ideas with fullerenes
GAINESVILLE, Fla. – A standard TV trope is the fuse made of a strand of gunpowder slowly burning while heading toward a pile of powder kegs and bundles of dynamite. This fire-starting scenario does, in fact, work, although nobody really does it that way. However,...
CEA-Leti Study Aims to Improve PDT
GRENOBLE, France, May 13, 2010 — CEA-Leti, a public research and technology company based in France, announced the launch of the Target-PDT project designed to increase the effectiveness of photodynamic therapy (PDT) for treating cancer by developing a novel nanocarrier-based...
Biosensor Images Tumors
CHARLOTTESVILLE, Va., Aug. 12, 2009 — A new oxygen nanosensor created by coupling a light-emitting dye with a biopolymer simplifies the imaging of oxygen-deficient regions of tumors, said chemists at the University of Virginia who developed the material. Such tumors are associated with...
QD Core Given Gold Shell
SEATTLE, July 28, 2009 -- Nanoparticles have been developed to perform a wide range of medical uses, from imaging tumors to carrying drugs to delivering pulses of heat to destroy tumor cells. But rather than settling for just one of these, researchers at the University of...
Things I Want to See
Jan 1, 2009 — Photonics has changed the way we look at the world. It influences the way research is done, how we think about vision and even the routines of our daily lives. We at Photonics Spectra feel that the industry could go even further than it has,...
Cutting Cancer by Color
BOSTON, Aug. 21, 2008 — The key to a successful cancer surgery is the removal of all of the diseased tissue, but sometimes tumor boundaries can be difficult to track. However, researchers in Massachusetts have developed a new imaging system that highlights cancerous tissue...
Nano Pioneers Awarded $1M
OSLO, Norway, May 28, 2008 -- Scientists from the US and Japan who discovered quantum dots and carbon nanotubes, respectively, are among seven inaugural recipients of $1 million Kavli prizes, biannual awards for outstanding research in nanoscience, neuroscience and astrophysics....
Microdevice to Track Tumors
WEST LAFAYETTE, Ind., April 11, 2008 -- A wireless, needle-like injectable device has been designed to more effectively kill tumors by telling doctors the precise dose of radiation received and the exact position of tumors during treatment. Babak Ziaie, an associate professor in the...
Chip Performs Blood 'Biopsy'
CHARLESTOWN, Mass., Dec. 19, 2007 -- A microchip-based device the size of a business card uses 80,000 posts smeared with an antibody "glue" to capture hard-to-find tumor cells in blood samples, providing new information about the cells to help monitor and guide future cancer...
Holography Helps Measure Drug Action in Cells
WEST LAFAYETTE, Ind., March 26, 2007 -- Using a laser and the same microchip found in digital cameras, a new digital holographic imaging system peers inside tumor cells and produces real-time, 3-D images that can be used to measure response to anti-cancer drugs. The device also may have...
