A new technique allows radiologists to lower the radiation dose that computed tomography (CT) delivers by tailoring the dose based on a childs size, according to a study appearing in the August issue of the journal Radiology.
"The purpose of our research was to provide the technologists who run CT scanners with a precise recipe for lowering the radiation dose levels for pediatric patients by matching radiation to body size, while still delivering a high-quality CT scan," said the studys lead author, John M. Boone, Ph.D. "There is a well-established need for this type of formula for dose reduction in pediatric CT," said Dr. Boone, professor of radiology and bioengineering at the University of California Davis in Sacramento.
The researchers studied CT images acquired using simulated pediatric patients of varying sizes to determine the lowest radiation doses achievable without loss of image quality. The resulting technique charts provide guidance for both head and body CT for pediatric patients from infancy to adolescence.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
