RADIOGRAPHIC
PRINCIPLES OF RADIOGRAPHIC IMAGING EXAM QUESTIONS AND
ANSWERS WELL ILLUSTRATED.
AEC Stands for answer >>> Automatic Exposure Control
Old term for AEC answer >>> Photo timing
T or F: AED (Automatic exposure device/detector) is the same as AEC answer >>>
True
What is the main purpose of AEC? answer >>> To eliminate the need for the
radiographer to set an exposure time.
Also, to provide consistency in images for the radiographer.
What factors does the tech have to set when using AEC? answer >>> mA, kept,
FSS
What technical factor does AEC not allow the tech to set? answer >>> Time, and
therefore mass
What does APR stand for? answer >>> Anatomical Programmed Radiography
What is APR? answer >>> When you select the body part and patient size on the
control counsel and suggested techniques settings automatically appear. (must
always confirm these are accurate)
, RADIOGRAPHIC
What is critical when using AEC? (Considering positioning) answer >>> That the
tissue or body part being examined is positioned properly over the ionization
chambers.
The art of AEC is the art of ________________ answer >>> Positioning
How many ionization chambers are typically used with AEC? answer >>> Three
What is the configuration of the ionization chambers? answer >>> The center
chamber at the center of IR and the right and left chambers slightly higher.
Why is this ionization chamber arrangement used? answer >>> - The center
chamber is below the duodenum and transverse colon for most abdominal
exams.
- Places the left and right chambers away from the mediastinum and completely
within the lobes of the lungs during a chest x-ray
Why is the ionization chamber being below the duodenum and transverse colon
during abdominal exams important? answer >>> It eliminates problems with
gastric and bowel gas being placed over the ionization chambers
How do you determine where the ionization chambers are if they are not
marked? answer >>> Produce and image without anything in front of the
Bucky/IR at a very low kept for maximum contrast.
T or F: No more than one ionization chamber may be activated at any time.
answer >>> False
