______ controls the kilovoltage, and thereby the wavelength and penetrating power, of the x-ray beam
_______________. These devices terminate the exposure when a specific quantity of radiation has reached the IR.
automatic exposure control (AEC)
________ is a measure of the current flow rate in the x-ray tube circuit. It determines the number of electrons available to cross the tube and thus the rate at which x-rays are produced.
increase in kVp will produce a ____ image, whereas a decrease in kVp will produce a ____ image.
The distance between the source of the x-ray beam (the tube target) and the IR is referred to as the ________
source-image distance (SID).
What are make up the four elements of radiographic quality:
The overall blackness of the image is referred to as the ______
optical density (OD),
an increase in _____ will result in a darker radiograph, whereas a decrease will cause it to be lighter.
OD is controlled by the exposure factors, primarily the ______.
distance between the source of x-rays and the IR (the SID) and the distance between the object and the IR, referred to as the ______
object-image distance (OID
Increasing ____ sharpens the image, whereas increasing the ___ reduces sharpness.
_______ refers to the sharpness of the image.
_______ refers to a variation in the size or shape of the image compared with the object it represents
