FAUBER Ch:3,4 Test Review(LXMO)
What is the lost of some energy from the x-ray beam as it passes through the tissue being imaged? -
Beam attenuation
The photoelectric affect involves the removal and or ejection of an electron. This process of removing an
electron from an atom is? - Ionization
When the x-ray photon strikes an atom within the tissue being imaged and looses "all" of it's energy to
an "inner" shell electron of an atom the photon is set to have been ________ to undergo ________? -
absorb; photoelectric interaction
When the x-ray photon strikes an atom within the tissue being imaged and looses only "part" of it's
energy to an "outer" shell electron of an atom the photon is set to have been ________ and undergo
________? - scattered; Compton effect
When the entering x-ray photon looses energy and changes it's path of travel as a result of interacting
with an atom, the interaction is known as? - Compton effect
The x-ray photon that is scattered as a result of the compton effect cannont what? - Cannot strike
the image receptor, and provide useful information
Interactions of high energy x-rays (energies beyond the disgnostic range) witht the tissue include: 1. Pair
production 2. Coherent scattering 3. Photo disteration? - Pair production and photo disteergation
Name of an Interaction with low energy x-rays, below the diagnostic range? - Coherent scattering
The x-ray beam that leads the patient in the direction of the image receptor is often referred? -
Remnant radiation
Unwanted exposure to the IR due to scatter radiation is? - Fog
, The ______ image occurs first on the image receptor and the _____ image occurs following proper
image processing? - Latent image; manifest images
At higher kv ______ photon interactions occur resulting in _______ transmissions? - fewer;
increase
Brightness/ density is a quality related to the ________ of the radio-graphic image? - Visibility of
structures
Remnant or exit radiation will be reduced by one half for every additional _______ of part thickness? -
4 to 5 cm
Contrast is a quality related to the _____ if the radio-graphic image? - Visibility of structures
Muscle tissue absorbs more radiation than fat tissue because muscle tissue has ______? - higher
tissue density
The amount of luminescence of a displayed monitor is? - brightness
The overall blackness of the process images is? - Density
Difference in the brightness levels or densities is? - Image contrast
An image that has excessive brightness or insufficient density is________? - Unacceptable
Subject contrast is dependent on ___________? - Energy of the x-ray beam and absorption
characteristics of tissue being image. Option A and C
The number of shades of gray that can be displayed by a computer system is? - Grayscale
