Therefore, they are replaced by more recent, advanced radiographic methods, such as computed tomography, (cone beam computed tomography--CBCT and fan beam
computed tomography--FBCT), as well as digital volume tomography (DVT).
With its sound technological expertise and vast experience, GE has leveraged its nondestructive testing technology by implementing its unique scatter | correct technology into CT systems that combine the high precision of a fan beam
CT system with the up to 100 times increased throughput of cone beam CT inspection," said Frost & Sullivan Industry Analyst Mariano Kimbara.
The systems will feature pencil-beam scanning and will be outfitted with CBCT and Fan Beam
CT imaging technology along with an advanced workflow system.
64-slice fan beam
true CT imaging for diagnostic image quality
As the tungsten blades of a collimator, located just beneath the X-ray tube, move from side to side, so the X-ray fan beam
sweeps back and forth.
As the product is transported along the conveyor, it passes through the X-ray fan beam
and absorbs some of the x-rays.
An analysis of the integral kernels for two well-known fan beam
CT reconstruction algorithms has been performed.
In a typical application, a panoramic x-ray source that emits a fan beam
of x-rays in an angle >180[degrees] is inserted inside of the tire under inspection and aligned with the internal collimator aperture opening.
The thickness of the fan beam
may be as small as 1 millimeter or as large as 10 millimeters.
With synchrotron radiation, the DEI method employs a single-energy fan beam
of X-rays instead of the broad-energy beam of conventional radiography.
The Elpar reflector has an elliptical shape in elevation and a parabolic shape in azimuth, which produces a vertically oriented fan beam
In rating TomoTherapy, MD Buyline wrote, "TomoTherapy is the only vendor for the CT-based linear accelerator which delivers radiation dose in a helical or fan beam
