RADIOGRAPHIC IMAGING EXAM QUESTIONS AND ANSWERS GRADED
A+!!
Name the 3 classes of diagnostic radiographic imaging. answer > film screen radiography
fluoroscopic imaging
digital/computerized imaging
What are the 4 x-ray production requirements? answer > x-ray tube with a vacuum inside
source of electrons
method to accelerate electrons to great speed
method to stop electrons
Name the 4 classes of radiation. answer > primary, scatter, absorbed, & remnant radiation
What is the loss of radiation energy as a result of passing through an absorbing material?
answer > Attenuation
High attenuation occurs in ______ matter. answer > radiopaque
Low attenuation occurs in ________ matter answer > radiolucent
T/F: the latent image is an invisible image on a phosphor plate before being converted into a
digital image. answer > True
, RADIOGRAPHIC
T/F: fluoroscopic imaging is static while radiographs are dynamic. answer > False. Fluoroscopic
images are moving or "in motion" images making them dynamic. Radiographs are still images
and therefore, static.
Will a radiopaque object appear black or white on a radiograph? answer > white
What is an example of something that is radiolucent? answer > air
What is the difference in absorption of x-rays by different body tissues? answer > differential
absorption
Name the 4 technical exposure factors. answer > mA
time (seconds)
kept
SID
The two main categories of radiographic quality are ______ and ______. answer >
photographic, geometric
What is the overall darkness or blackness of an image referred to as? answer > image density
image density is primarily affected by? answer > mA
exposure time
SID
mass represents what? answer > the quantity of x-ray production
mass is calculated by doing what? answer > multiplication of mA and exposure time (S)
