Many physical factors affect the properties of scatter including energy spectrum of the beam, thickness and size of the object, and collimation. Using physics and empirical modeling, SmartGrid software can accommodate these factors through estimation of the algorithm parameters that are tuned to replicate anti-scatter grid visual performance.

Correct patient labeling, radiation safety, and x-ray beam centering and collimation were not associated with a determination of diagnostic quality for radiograph sets.

Unlike a refractor, a reflector's optics require occasional collimation, which involves adjusting the telescope's two mirrors so they're properly aligned with each other.

Three thorough appendices cover collimation, field-testing a telescope's optics and polar alignment, and there is a twelve page index.

Toshiba will demonstrate the new capabilities of the Infinix-i including WorkRite technology to showcase the system's flexibility, superior ergonomics and patient-access features during transradial procedures; Spot Fluoroscopy, a new, unconventional way to provide collimation, giving physicians the ability to see more clinical information outside the live fluoro region of interest (ROI); Access Halo, the Infinix-i's unique design that provides 180 degrees of direct head-end patient access for clinical teams during advanced procedures with maximum efficiency and safety and Transaortic Valve Replacement (TAVR) software that supports the planning and deployment phases for this procedure.

The solar divergence is accurately reproduced combining the sphere output diameter S to the focal distance [f.sub.C] of the collimation optics, which can be a lens or a mirror.

On 3D images, 15 orbits received a score of 1, each acquired at 1.25 mm collimation. Five cases received a score of 0, all acquired at 2.5 or 5 mm collimation.

Made by Coherent, the StingRay series mates a diode laser with high performance electronics and precision refractive optics for collimation and line generation covering the widest available range of fan angles.

Previous researchers have used a compound parabolic concentrator (CPC) for this purpose, yet it takes a very large CPC to achieve the high degree of collimation needed.

The dark room processing faults are also completely eliminated, thus leaving out beam collimation and good technique as the major potential sources of patient's over exposure (6).

Some examples of specific topics include the importance of astronomical plat archives as complementary support for astroparticle physics, dark energy models toward observational tests and data, high-energy gamma-rays from massive binary systems, anisotropy of ultra-high-energy cosmic rays from the surface array data of the Pierre Auger Observatory, jet collimation by magneto-torsional oscillations, the physics of the interaction of astrophysical jets with the interstellar and intracluster medium, galactic versus extragalactic sources for cosmic rays, neutrino astronomy with the IceCube Observatory and implications for astroparticle physics, and probing gravity in the Earth-Moon system.

Can locate areas of interest on a sample using the integrated color CCD camera and optional integrated 3-mm collimation.
