Film-screen or digital are examples of:
a. x-ray room types
b. image receptors
c. x-ray beam characteristics
d. none of the above - correct answer ✔✔image receptors
In producing a radiographic image, which of the following occurs last?
a. differential absorption
b. quality and quantity of x-ray beam is set at console
c. radiation interacts with image receptor
d. radiation exits the patient with different energies - correct answer ✔✔radiation interacts with image
receptor
Differential absorption occurs because different tissues have varying amounts of:
a. photoelectric interactions
b. Compton scattering
c. coherent scattering
d. pair production - correct answer ✔✔photoelectric interactions
Complete absorption of the diagnostic range x-ray photon is the interaction known as:
a. Compton scattering
,b. photoelectric interaction
c. classical scattering
d. photodisintegration - correct answer ✔✔photoelectric interaction
The ability to remove electrons from an atom is:
a. absorption
b. transmission
c. ionization
d. none of the above - correct answer ✔✔ionization
The secondary photon that results from the photoelectric interaction:
a. has the same energy as the incident photon
b. has high energy
c. has low energy
d. typically leaves the patient as scatter radiation - correct answer ✔✔has low energy
The probability of a Compton interaction is __________ in bone than soft tissue:
a. less
b. the same
c. higher
d. none of the above - correct answer ✔✔the same
Coherent scattering:
a. is a significant interaction during radiographic imaging
b. has minimal effect on the imaging process
, c. never affects the diagnostic image
d. none of the above - correct answer ✔✔has minimal effect on the imaging process
Transmission refers to:
a. all x-rays in the beam before entering the patient
b. x-rays leaving the patient that did not interact with atoms
c. all x-rays leaving the patient
d. the process of sending the x-ray beam through the patient - correct answer ✔✔x-rays leaving the
patient that did not interact with atoms
Decreased attenuation results in:
a. more x-rays photons reaching the image receptor
b. fewer x-ray photons reaching the image receptor
c. no change in the number of photons reaching the image receptor
d. none of the above - correct answer ✔✔more x-rays reaching the image receptor
Imaging a thicker part results in:
a. more x-rays photons reaching the image receptor
b. fewer x-ray photons reaching the image receptor
c. no change in the number of photons reaching the image receptor
d. none of the above - correct answer ✔✔fewer x-ray photons reaching the image receptor
Tissues with higher atomic numbers appear _________ on a digital image.
a. darker
b. lighter
