Each digital image is formed by two-dimensional elements termed:
Highly complex mathematical formulas used in creating the digital image are termed:
Changes in kV have little impact on patient dose with digital imaging.
kV and mAs do not have the same direct effect on image quality with digital imaging as they do with IR screen imaging.
A wide exposure latitude associated with digital imaging systems will reduce repeat exposures.
The intensity of light that represents the individual pixels in the image on the monitor is termed:
The primary controlling factor of contrast in the digital film image is:
The greater the bit depth of a digital system, the greater the:
What term describes the minimum pixel size that can be displayed by a monitor?
Display pixel size
OID and SID have little impact on spatial resolution of the digital image.
The current range of spatial resolution for digital general radiographic imaging is between 2.5 to 5 lp/mm.
A numeric value that is representative of the exposure the image receptor received is termed:
Random disturbance that obscures or reduces clarity is:
If an acceptable exposure indicator range is between 2.0 and 2.4, an exposure indicator of 4.0 would indicate overexposure.
A high SNR results when insufficient mAs is used in creating a digital image.
Which of the following factors will result in an increase in noise?
decrease in pixel size
Changing or enhancing the electronic image to improve its diagnostic quality describes:
__________ is the application of specific image processing that alters the pixel values across the image so as to present a more uniform image appearance.
Window width controls the ________ of the digital image
Post-processing can correct for a low SNR image.
