Low-dose MDCT of the sinuses in children is effective in diagnosing conditions such as sinusitis and middle ear fluid with a radiation dose comparable to standard x-rays. It also has more benefits, such as better accuracy, speed and a broader diagnosis potential, say researchers from Heilig Hart Hospital in Belgium.
For the study, the researchers compared the imaging results of 69 children who had undergone x-rays and 125 children who had undergone low-dose MDCT. They found that the mean effective radiation dose in x-rays was 0.0528 mSv and that the mean effective radiation dose for MDCT could be brought down to 0.0531 mSv without compromising diagnostic image quality.
According to the researchers, infections of the upper respiratory system are by far the most common cause of illness in infancy and childhood, accounting for approximately 50% of all illness in children younger than five years of age, and 30% in children between the ages of five and 12 years. “About 5 to 13% of these upper respiratory infections are complicated by sinusitis, so it is a common problem with children,” said Tom Mulkens, MD, lead author of the study.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
