True of False: Most modern radiographic equipment is equipped with automatic exposure control devices:
|
True
|
|
|
True of False: One problem with the use of automatic exposure devices is over dependence resulting in a lack of ability to work with manual techniques:
|
True
|
|
|
When using automatic exposure control devices "AEC" what exposure factor is selected by the AEC?
|
Time

|
|
When using AEC the radiographer would or would not set the KVp:
|
Would
|
|
|
When using AEC if the Kvp is high the patient dose is relatively high or low?
|
Low
|
|
|
When using AEC if the Kvp is high the radiographic contrast will be relatively high or low?

Low
|
|
|
When using AEC the Radiographer does or does not set the mAs?
|
does not
|
|
|
When using back up time the time set should be set to no more than what amount?
|
Twice the expected mAs
|
|
|
Where it the ionization type AEC chamber is located:
|
Between the patient and the image receptor.
|
|
|
True or False: The number of chambers used for AEC may vary:
|
True
|
|
|
True or False: The choice of field is not an important factor in the use of AEC:
|
False
|
|
|
If when radiographing the spine the chamber used is positioned under the lung the resulting radiograph will be:
|
Under exposed
|
|

AEC is or is not recommended for barium studies like the small bowel:
|
is not
|
|
|
Automatic exposure control devices are used to keep what radiographic quality equal on all patients?
|
Density
|
|
|
The maximum time that an AEC exposure will continue is known at what?
|
Back up time
|
|
|
Which type of automatic exposure control device is the most accurate?
|
Ionization chamber

|
|
What might be the probable cause of a lack of density in barium enema air contrast radiograph taken in conjunction with an automatic exposure control device?
|
Air located above the AEC cell
|
|
|
When radiographing the lumbar spine in the lateral position if the abdomen instead of the spine is located above the sensor, would the radiograph be diagnostic?
|
Yes
