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.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
