Used to measure spatial frequency (Lp/mm) of an image/system.
The result of the number of pixels as matrix size increases.
What is MORE
Also referred to as an "invisible image"

What can be adjusted to alter the midpoint of the range of brightness levels visible on the digital image?
What is window level
Color of light that is used to stimulate an exposed PSP plate.
What is red.
What is the amount of distortion when the anatomy is placed directly against the IR?
What is less.
What interaction primarily contributes toward photon scattering?
What is Compton effect interaction.
An MTF of this amount provides a perfect reproduction of the structure being imaged.
What is 1.
Brightness and contrast can be described broadly as what?
What is visibility
Utilizing masking/cropping can help to avoid excessive light from showing on the manifest image and prevents this from occurring.
What is veil glare.
What is happens to spatial resolution when the pixel density is increased and pixel pitch is decreased?
What is more (improved/better).
What refers to the range of exposure intensities an image receptor can accurately detect?
What is the dynamic range.
An increase in angulation (tube and/or part) that displays the image being longer than the true shape.
What is elongation
The difference in brightness levels between 2 adjacent structures?
What is (subject) contrast.
A common element/material used in the scintillators for both types of indirect capture DR.
What is cesium iodide.
A ____ SNR can cause quantum noise in the image.
The difference between the x-ray photons that are absorbed photoelectrically & those that penetrate the body.
What is differential absorption.
What is dose area product (DAP).
Artifact that occurs from insufficient mAs being utilized during an exposure.
What is (quantum/random) noise.
The primary controller of IMAGE contrast.
What is the look-up table.
Differential absorption increases when there is _____ kVp used.
What is less (decrease in kVp)
