A new magnetic resonance imaging (MRI) technology reduces brain-imaging time from 20 minutes to three minutes while maintaining accuracy and decreasing patient discomfort, according to early research results presented at the 89th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA).
"The three-minute head scan is as good as the 20-minute version, and in some instances better because stroke patients may be distressed and move around," said study co-author, Jonathan H. Gillard, M.D. "Pictures taken in a shorter period of time are less susceptible to degradation from the patient moving during the scan." Dr. Gillard is a lecturer and honorary consultant neuroradiologist at Addenbrookes Hospital, University of Cambridge in England, where the study is ongoing.
To be successful, treatment with intravenous thrombolytic (clot-busting) drugs must typically begin within three hours after stroke onset. Interventional radiology has increased the critical treatment window through the use of catheters that deliver the drugs directly to the clot in the brain, but every minute counts. Therefore, it is essential that stroke patients be diagnosed quickly, so that treatment can begin. Computed tomography (CT) is the usual method for diagnosing stroke, because it only takes a few minutes, compared to 20 minutes with conventional MRI. However, unlike MRI, CT does not identify the parts of the brain that are at risk of damage.

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.
Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.
In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
