Optical Measurements Combine for Early Metastasis Detection
BOSTON, Aug. 10, 2023 — Diffuse in vivo flow cytometry (DiFC), an optical technique developed at Northeastern University, enables fluorescence detection of tumor cells circulating in the bloodstream. It is a promising technique for detecting cancer that has metastasized....
Technique Enables In Vivo Vascular Imaging at Single-Cell Resolution
HONG KONG, Sept. 22, 2022 — A two-photon fluorescence imaging method developed by researchers at the University of Hong Kong and the University of California, Berkeley was able to image the flow of individual blood cells at 1000 2D frames and 1,000,000 line-scans per second in...
Widened 3D Field of View Enhances OCT Diagnostic Imaging
WASHINGTON, D.C., June 8, 2022 — Researchers at Duke University developed an optical coherence tomography (OCT) technique that delivers high contrast and high resolution over a wide, 3D field of view. The enhanced OCT technique, called 3D optical coherence refraction tomography (3D...
Pseudo-Random Speckle Illumination Patterns Allow for High-Resolution Imaging
TOKYO, Feb. 6, 2020 — Researchers at the University of Tokyo have demonstrated the use of a multimode fiber (MMF) in combination with an integrated optical phased array (OPA) chip for single-pixel imaging in potential biomedical applications. The technology could allow...
In Vivo Imaging with FLIM Shows Effect of Experience on Neuronal Activity
JUPITER, Fla., Dec. 30, 2019 — Every day, the neuronal connections within our brains change depending on what we learn and experience in our daily lives. Specialized proteins, called activity-dependent transcription factors, activate genes within the cells of the brain to help it...
Approach Uses Bayesian Analysis to Speed Spectroscopy Results
PHOENIX, Aug. 19, 2019 — Scientists from Arizona State University are leveraging the tools of data science to study molecular activity more quickly than is possible through traditional fluorescence correlation spectroscopy (FCS). While FCS provides estimates of dynamical...
Antibody-based Probe Developed for Live-Cell Imaging in Vivo
FORT COLLINS, Colo., July 5, 2019 — To expand the toolbox of imaging in living cells, researchers from Colorado State University and the Tokyo Institute of Technology have developed a genetically encoded, antibody-based probe that works with specificity in vivo. In this methodology,...
LOTUS-V Brain Imaging Technique Shows Promise In Neuroscience
OSAKA, Japan, June 7, 2019 — Researchers at Osaka University have developed a method to record brain activity in multiple freely moving mice simultaneously. The method is based on a recent bioluminescence-based indicator of membrane voltage. Researchers applied the indicator...
Lumicell Technology Assessed for Tumor Removal in First Surgery
NEWTON, Mass., April 19, 2019 — Researchers at Massachusetts General Hospital (MGH) in Boston are conducting a feasibility study to determine the initial safety and efficacy of its Lumicell System for in vivo imaging of metastases in the hopes of removing all cancer during a first...
Three-Photon Microscope Reveals Cortical Layers of Mouse Brain
CAMBRIDGE, Mass., Jan. 15, 2019 — A new three-photon microscope developed at the Picower Institute at the Massachusetts Institute of Technology (MIT) can deliver rapid, short, low-power pulses of light capable of reaching deep targets within the brain without causing functional...
Diffractive Catheter Enhances OCT Imaging
BALTIMORE and SEATTLE, March 12, 2014 — A new imaging catheter that enables real-time, ultrahigh-resolution OCT imaging at 800 nm to form a 3-D volumetric dataset could potentially improve image contrast via increased light scattering and less tissue absorption.
Mass-Market Imaging Systems Cut Time, Cost, Size
Jan 1, 2012 — “Smaller,” “cheaper” and “faster” seem to be the current buzzwords in the imaging industry – and some of the imaging components on the horizon may allow us to enjoy industrial capabilities in our everyday...
Plasmonic resonances found in quantum dots
BERKELEY, Calif. – Until recently, plasmonic properties have been limited to nanostructures with interfaces between noble metals and dielectrics. But now researchers have discovered that plasmonic properties also can be achieved in quantum dots. Scientists at the...
Xenogen, Biogen Collaborate on In Vivo Imaging
May 22, 2003 — ALAMEDA, Calif., May 22 -- Xenogen Corp. announced today it has entered into an agreement with Biogen Inc. to evaluate Xenogen's proprietary real-time in vivo imaging technology in their discovery research programs. This technology is expected to...
