collimators's Usage Examples:

Slat collimators defined a FOV of 3° × 30° (FWHM) for each detector; the long axes of.

One of the main features is the array of 128 collimators and position sensitive detectors for rapid data acquisition.

and engineers to design lenses, reflectors, optical instruments, laser collimators, and illumination systems.

monochromator designs do use focusing gratings that do not need separate collimators, most use collimating mirrors.

They may be interchangeable orifices with different diameters, typically varying from 5 to 40 mm in 5 mm steps, or multileaf collimators.

images of rodents with a high resolution were based on use of pinhole collimators attached to convectional gamma cameras.

rotating collimators, wire collimators), the technology most currently used on present days employs.

Modern linear accelerators are equipped with multileaf collimators (MLCs) which can move within the radiation field as the linac gantry.

"Three dimensional conformal treatment planning with multileaf collimators".

Optical collimators can be used to calibrate other.

energy of the photon, 159 keV, is ideal for the NaI (sodium iodide) crystal detector of current gamma cameras and also for the pinhole collimators.

arrangement has the advantage of simplicity and relatively low cost, but the collimators reduce intensity and increase scattering, and reduce the area of sample.
