QUESTIONS and CORRECT Answers
Bowel gas in the abdomen would be an example of a _____ material, with regard to the x-ray
beam. - CORRECT ANSWER - radiolucent
All of the following are related EXCEPT: - CORRECT ANSWER - a lead barrier to stop
the production of heat formation.
The loss of radiographic image resolution is often referred to as "unsharpness." All of the
following contribute to total image unsharpness EXCEPT the: - CORRECT ANSWER -
pixel size of the image receptor (IR) and monitor display.
The invisible, unprocessed data on an image detector immediately after x-ray exposure form the
_____ image. - CORRECT ANSWER - latent
The production of x-radiation that occurs in an x-ray tube requires the movement of negatively
charged particles traveling from one side of the tube to the other. This movement of charges must
occur in: - CORRECT ANSWER - a vacuum.
As you position patients for various radiographic procedures, you will occasionally angle the x-
ray tube assembly. This intentional use of tube angles is referred to as: - CORRECT
ANSWER - shape distortion.
Indirect capture digital radiography is unlike direct capture technology in that indirect
technology uses: - CORRECT ANSWER - a scintillator material to produce light in a two-
step process.
As you perform a portable chest radiograph, the optimal SID of 40 inches is unattainable because
of orthopedic supports over the patient. It is necessary for you to shorten the SID to 34 inches. A
professional radiographer should do which of the following? - CORRECT ANSWER -
Indicate the shorter SID on the examination notes to the radiologist.
, Of all of the energy traveling through the x-ray tube during a radiographic exposure, the largest
percentage of this electrical energy is converted to: - CORRECT ANSWER - thermal
energy (heat).
In a film-based imaging department, automatic processors are an indispensable part of
departmental operations. From the choices below, which is NOT TRUE regarding automatic film
processing? - CORRECT ANSWER - They are maintenance-free and require annual
cleaning.
Inadequate mAs exposures in CR imaging technology will yield an image that is: - CORRECT
ANSWER - grainy and demonstrates quantum mottle.
All of the following are true of computed radiography (CR) EXCEPT: - CORRECT
ANSWER - the image is recorded on an amorphous silicon digital detector plate.
As you process a radiographic image of the abdomen of a small child, you notice a small ringlike
object on the image. It appears this object is in the patient's stomach, which is consistent with the
examination history. The ring shows on the x-ray image because of its metallic density. This is
the result of: - CORRECT ANSWER - attenuation of the x-ray beam by the metallic
density of the ring.
When radiographic images of patients are created, many exposure variables come into play to
produce optimum image quality. Any change in the radiographic image impression should be the
result of: - CORRECT ANSWER - the patient's medical condition as reflected in the image
characteristics.
X-ray film imaging has been replaced by: - CORRECT ANSWER - all of the above.a.
computed radiography (CR).
direct digital detector technology.
digital radiography systems.
