CE ÎNSEAMNĂ COLLIMATOR ÎN ENGLEZĂ?
Înălțător
Un colimator este un dispozitiv care îngustă un fascicul de particule sau valuri. A "îngust" poate însemna ori să determine direcțiile de mișcare să devină mai aliniate într-o anumită direcție, fie să determine ca secțiunea transversală a fasciculului să devină mai mică.
Definiția collimator în dicționarul Engleză
Prima definiție a colimatorului din dicționar este un telescop mic atașat unui instrument optic mai mare ca ajutor pentru fixarea liniei sale de vedere. O altă definiție a colimatorului este un sistem optic de lentile și fante care produc un fascicul de lumină nedivertant, de obicei pentru utilizarea în spectroscoape. Colimatorul este, de asemenea, orice dispozitiv pentru limitarea dimensiunii și a unghiului de răspândire a fasciculului de radiații sau particule.

The Essential Physics of Medical Imaging
Pinhole collimators are used extensively in pediatric nuclear medicine. A
converging collimator (Fig. 21-6) has many holes, all aimed at a focal point in
front of the camera. As shown in Fig. 21-6, the converging collimator magnifies
the image.

Emission Tomography: The Fundamentals of PET and SPECT
Although this selective absorption is necessary for the creation of the images, it is
also very inefficient because most of the gamma rays are absorbed in the
collimator. For the collimators used in nuclear medicine, only about one in ten ...

Sensitivity An estimate of the sensitivity of a collimator can be computed from
simple geometry. A useful measure is the sensitivity of the collimator per unit area
of collimator to a plane source of activity placed in front of it. It is easily shown
from ...
