A novel technique that uses mammography to determine the biological tissue composition of a tumor could help reduce unnecessary breast biopsies, according to a new study appearing in the journal Radiology. Mammography has been effective at…

A terahertz laser designed by MIT researchers is the first to reach three key performance goals at once -- high constant power, tight beam pattern, and broad electric frequency tuning -- and could thus be valuable for a wide range of…

More than one in eight people aged 75 and older in the United States develop moderate-to-severe blockage of the aortic valve in their hearts, usually caused by calcified deposits that build up on the valve's leaflets and prevent them from…

Harnessing nuclear fusion, which powers the sun and stars, to help meet earth's energy needs, is a step closer after researchers showed that using two types of imaging can help them assess the safety and reliability of parts used in a…

It has been difficult to simultaneously obtain micro- and macroscopic information in outer space. Global images of distant astrophysical phenomena provide macroscopic information; however, local information is inaccessible. In contrast, in…

New accelerator-based technology being developed by the Department of Energy's SLAC National Accelerator Laboratory and Stanford University aims to reduce the side effects of cancer radiation therapy by shrinking its duration from minutes…

Researchers from the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) have found a new method for obtaining high-quality images in magnetic resonance imaging (MRI), that requires less contrast medium compared to current…

A new study led by The Australian National University (ANU) has discovered a promising way to significantly lower doses of X-rays that has the potential to revolutionise 3D medical imaging and make screening for early signs of disease much…

Medical physicist Dr. Aswin Hoffmann and his team from the Institute of Radiooncology -- OncoRay at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) are the first researchers worldwide to combine magnetic resonance imaging (MRI) with a…

Biotechnologists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have developed a system to accurately measure muscle weakness caused by structural changes in muscle tissue. The new method allows muscle function to be assessed…
