Using a back projection algorithm the cones are overlaid to create the radiation image (i) in angular space (Azimuth \(\Theta\), Altitude \(\Phi\)) for either gamma rays or fast neutrons. The user is then shown a 3D projection of the image in MR. Full size image The H2DPI consists...
Nevertheless, the Cd contamination of rice is still a serious threat to Japanese people and other populations in the world that consume rice as a staple food, because rice is a major source of dietary intake of Cd. Understanding how Cd is taken up by rice roots and subsequently transported ...
Background: Polymer-carbon nanostructures have previously been introduced for dosimetry of gamma rays with potential application in radiotherapy. In this research work, bismuth oxide (Bi2O3) nanoparticles were added into the amorphous polycarbonate (PC) matrix to enhance the probability of ...
I would also like to see summaries for various facets of the field of ray tracing. For example, I think of Larry Gritz’s article“The Importance of Being Linear”fromGPU Gems 3as a great example of this type of article. It is about gamma correction – not a new topic by any stretch...
s Brave New World. Humanity requires a larger and freer habitat. We do not live by bread alone. The fundamental problem of man’s future is not economic but spiritual, the problem of diversity. How do we find room for diversity, either on our crowded earth or in the metal-and-glass ...
When an astronomer discovered a brief bolt of energy that could travel billions of light-years, he was astonished. Then decades went by without evidence of another.
However, it is difficult to acquire and reconstruct dy- namic volumes from the physical world with high fidelity. First, the samples from common 2D imaging sensor(s) are usually not the direct measurements of a 3D volume. Fur- thermore, the dynamic ...
Gamma Rays From a Dwarf Galaxy Solve an Astronomical PuzzleSeptember 06, 2022 A glowing blob known as “the cocoon”, which appears to be inside one of the enormous gamma-ray emanations from the centre of our galaxy dubbed the “Fermi bubbles”, has puzzled astronomers since it was discovered...
[0021] In another possible implementation of the performance capture system, a stereo display is included and configured to display one of the at least one enhanced image as a left eye view and one of the at least one enhanced image as a right eye view. For example, the performance capture...
Ionizing gamma rays and x-rays can cause cancer when their energy is absorbed by the tissue and chemical bonds are broken, damaging DNA. RF energy, on the other hand, produces heating of tissue. Although there is a small amount of experimental evidence that suggests RF energy can impact DNA...
