A team of Dartmouth engineers and doctors are trying to find more comfortable and comprehensive ways to examine breast tissue to better detect and diagnose breast cancer. The Dartmouth group is simultaneously developing and testing four different breast imaging techniques.
The multidisciplinary Dartmouth team includes researchers from the Thayer School of Engineering and Dartmouth Medical School, and they are working under the auspices of the Norris Cotton Cancer Center and the department of radiology at Dartmouth-Hitchcock Medical Center. Halfway through their five-year, $7 million grant from the National Cancer Institute to study four techniques for breast imaging, the group is learning a great deal about breast tissue structure and behavior through magnetic resonance elastography (MRE), electrical impedance spectral imaging (EIS), microwave imaging spectroscopy (MIS), and near infrared (NIR) spectral imaging.
Its the combination of these four techniques that sets the Dartmouth program apart. Their rationale is that one of the methods by itself may not provide the complete picture, but by using more than one technique, there should be added value.
During the first two and a half years of this five-year National Cancer Institute grant, the group has made significant progress on the technical aspects of the imaging techniques. They have improved the tools and manner of delivery so the exams are more comfortable for the participants.
For the next two and a half years, the researchers will focus on a controlled trial with 150 subjects. The goal is to rigorously test the four techniques and gather data to inform the detection of abnormalities and their subsequent diagnoses.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
