Why is it important for the radiographer to observe the
milliampere seconds (mAs) readout at the end of each
exposure when using automatic exposure control (AEC)? -
Answer-This value may be used as a basis for calculating
manual techniques.
How does emphysema impact radiographic imaging of the
chest? - Answer-Emphysema is a destructive disease,
meaning the chest tissue is more radiolucent.
If computed radiography (CR) imaging plates (IP) haven't
been used, how often should they be erased? - Answer-48
hours.
In which way can the radiographer minimize motion due to
peristalsis? - Answer-Decrease exposure time.

Which best describes anode heel effect? - Answer-A
phenomenon where x-ray intensity is greater under the
cathode.
Which will increase the appearance of noise in a digital
image, assuming only the named factor in each response
is changed? - Answer-Large matrix.
Which is the preferred method for indicating the correct
anatomic side on a radiographic image? - Answer-Place a
side marker directly on the image receptor (IR) prior to
exposure.
If a radiographer wanted to double image density without
doubling the patient's dose, which action should be taken?
- Answer-Increase kilovolts peak (kVp) by 15%
Which statement is correct regarding the relationship of
patient dose to exposure index (EI)? - Answer-EI gives an
approximation of the patient's dose.

What is a method of electronic display resolution quality
control testing? - Answer-Society of Motion Picture and
Television Engineers (SMPTE) test pattern.
A breathing technique is planned for a right anterior
oblique (RAO) sternum radiograph. The intended
exposure is 50 milliampere-seconds (mAs) at 75 kilovolts
peak (kVp) at 100 centimeter source to image receptor
distance (SID). Which milliampere (mA) station is
preferred, assuming the radiographer ensures exposure
occurs during the act of inspiration? - Answer-50
A step-up transformer with 300 turns in the primary coil is
supplied with 220 volts to this primary. How many
secondary turns are needed to produce a 66,000 volt
output? - Answer-90,000 turns
What is the result if the total lead content of a grid is
decreased? - Answer-Decreased scatter absorption.
What is the purpose of shuttering? - Answer-To black out
areas of light and make fine details more visible.

In conventional tomography, the radiographer is able to
control the thickness of the tomographic slice by altering
which of the following? - Answer-Exposure angle.
Which type of exposure technique chart would allow the
radiographer to make small, fine adjustments for
orthopedic work? - Answer-Variable kilovolts peak (kVp).
An imaging department, having difficulty obtaining
acceptable tangential patella images, has opted to have
the post processing mode set to "fixed" for all patella
images. Why is this a good choice? - Answer-Fixed mode
works well for exams where it is difficult to center the
image on the image receptor (IR).
Pelvis routine calls for an anteroposterior (AP) with a
perpendicular central ray (CR), and an axial AP with a 40
degree cephalic angle. Using a caliper measurement, the
technique chart yields a perfect set of exposure factors for
the perpendicular AP. How will the necessary exposure
factors for the axial differ from the perpendicular AP? -
Answer-Greater measurement, higher kilovolts peak (kVp)
and milliampere-seconds (mAs).
