Dartmouth physicians and engineers are collaborating to test three new imaging techniques to find breast abnormalities, including cancer. Results from the first stage of their research, information about the electro-magnetic characteristics of healthy breast tissue, appears in the May 2004 issue of Radiology, the journal of the Radiological Society of North America.
The interdisciplinary team, which includes researchers from Dartmouths Thayer School of Engineering and Dartmouth Medical School working with experts at the Norris Cotton Cancer Center and the Department of Radiology at Dartmouth-Hitchcock Medical Center (DHMC), is developing and testing imaging techniques to learn about breast tissue structure and behavior. The techniques are electrical impedance spectral imaging (EIS), microwave imaging spectroscopy (MIS), and near infrared (NIR) spectral imaging.
"This study offers the foundation for future research and clinical trials," says Steven Poplack, associate professor of radiology and OB/GYN at Dartmouth Medical School, doctor of diagnostic radiology and Co-Director for Breast Imaging/Mammography at DHMC, and the lead author of the paper. "Were establishing normal ranges for healthy breast tissue characteristics in order to more easily recognize the abnormalities."

The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.
Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.
