CDI Miami announces new x-ray diagnosis procedures that will improve the old practice of x-rays. Miami, FL (PRWEB) January 20, 2014 X-Ray imaging is the most widely known and used form of medical imaging in the world. A procedure using x-rays uses a small amount of radioactive energy on a specific area of the body in order to detect an anomaly in the tissue, such as a fracture or mass. The procedure is painless and safe, and takes very little time. When x-ray imagery first entered...

Our Understanding of the Universe MAXI-mized By The International Space Station
2014-01-16 08:31:10

NASA Look up at the night sky … do you see it? The stars of the cosmos bursting in magnificent explosions of death and rebirth! No? Well, then maybe you are not looking through the “eyes” of the Monitor of All-sky X-ray Image (MAXI) investigation, mounted on the exterior of the International Space Station Kibo module. MAXI, along with other sky watching instruments, such as Swift, collect data that help researchers discover, study and understand the physics behind the powerful...

Undergraduate students create, patent, market breakthrough technology Those have undergone extensive back surgery and need repeated X-rays to monitor their progress may soon have access to a new technology that skips the X-rays and repeated radiation exposure, opting instead for an innovative, noninvasive, non-X-ray device that evaluates spinal movement. The technology was created and patented by two engineering undergraduate students who recently formed their own company to market the...

Dead Star, Black Holes Highlighted In Dazzling NASA NuSTAR Imagery

Gerard LeBlond for redorbit.com - Your Universe Online A pair of dazzling images from NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) highlights the observatory's impressive imaging capabilities for objects both near and far. The first image (featured above) is of the energized remains of a dead star, labeled the “Hand of God” for its formation resembling that of a hand. the second image (see below) is of distant black holes surrounded by a cloud of dust. NuSTAR’s...

Radiation from cardiology procedures equals more than 50 chest X-rays per person each year Cardiologists are being urged to reduce patient radiation exposure in a European Society of Cardiology (ESC) position paper which outlines doses and risks of common cardiology examinations for the first time. The paper is published today in the European Heart Journal. Lead author, Dr Eugenio Picano, FESC, said: "Cardiologists today, are the true contemporary radiologists. Cardiology accounts for...

Newly Developed Holographic Process Uses Image-stabilized X-ray Camera
2014-01-07 11:40:04

Helmholtz-Zentrum Berlin A team headed by Stefan Eisebitt has developed a new X-ray holography method that will enable snap-shots of dynamic processes at highest spatial resolution. The efficiency of the new method is based on a X-ray focusing optics being firmly fixed to the object to be imaged. While this approach initially provides a blurry image, this can be focused in the computer based on the hologram information. At the same time, the rigid connection between the object and the...

Abell 2142, also called A2142 and located in the constellation Corona Borealis, is an X-ray luminous galaxy cluster. Its creation is due to the merger between two galaxy clusters. It is one of the largest objects in the universe and is six million light years across. It holds hundreds of galaxies and enough gas to make a thousand more. The pressure fronts in the system have been traced in detail and are relatively cool 50 million degree Celsius. The central region is embedded in large...

X-Ray Astronomy -- Although the more energetic X-rays (E > 30 keV) can penetrate the air at least for distances of a few meters (they would never have been detected and medical X-ray machines would not work if this was not the case) the Earth's atmosphere is thick enough that virtually none are able to penetrate from outer space all the way to the Earth's surface. X-rays in the 0.5 - 5 keV range, where most celestial sources give off the bulk of their energy, can be stopped by a few...

X-ray Burster -- X-ray bursters are a class of binary stars which are luminous in X-rays. They contain a neutron star and a low-mass companion star. The companion fills its Roche lobe and therefore the neutron star is accreting matter from it. The inflowing gas forms an accretion disk around the neutron star. Sometimes X-ray bursters show a sudden increase in their X-ray luminosity, called X-ray burst. All properties of the X-ray bursts can be explained assuming that they result from...

X-ray Binaries -- X-ray binaries are a class of binary stars that are very luminous in X-rays. The X-rays are produced by matter falling from one component (usually a relatively normal star) to the other component, which is a neutron star or a black hole. The infalling matter releases gravitational potential energy, up to several tens of per cent of its rest mass as X-rays. (Hydrogen fusion releases about 0.7 per cent of rest mass) X-ray binaries are further subdivided into...

Variable Star -- Most stars are of nearly constant luminosity. Our own Sun is a good example which goes through practically no measurable variation in brightness. There are, however, stars which do vary in brightness, called variable stars. They fall into two main groups: Intrinsic variables These are stars which have intrinsic variations in brightness, that is the star itself gets brighter and dimmer. There are many types of intrinsic variables, the main types being: -- Mira...
