16-MDCT is showing promise in detecting coronary artery atherosclerosis and could, in the near future, serve as an alternative to electron beam CT, a technique that is effective but not widely available, a new study shows.
The study of 100 patients at Hiroshima University in Japan found that 16-MDCT and electron beam CT were almost equivalent in detecting coronary artery calcifications and coronary artery calcium scoring. Calcium scoring is the "quantification of total calcium burden in the coronary artery," said Jun Horiguchi, MD, of the Hiroshima University School of Medicine. The score is expected to predict the patient’s risk for a heart attack, and can be used to track the progression or regression of coronary atherosclerosis, he said.
All patients in the study underwent both an electron beam CT examination and a 16-MDCT examination. 16-MDCT had a sensitivity of 98.7% and a specificity of 100%, Dr. Horiguchi said. The variability of calcium scores between the electron beam and MDCT scanners was comparable to earlier reports that had compared electron beam scanners to electron beam scanners, he added.

From June 25th to 27th 2019, the Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau (Germany) will be presenting a new solution for acoustic quality inspection allowing contact-free, non-destructive testing of manufactured parts and components. The method which has reached Technology Readiness Level 6 already, is currently being successfully tested in practical use together with a number of industrial partners.
Reducing machine downtime, manufacturing defects, and excessive scrap
The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.
Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
