Which change should be made when performing an abdomen radiograph on a
patient with ascites? ......ANSWER......Raise exposure factors.
Which system can store images? ......ANSWER......Picture archival and
communication system (PACS).

How often should lead aprons be evaluated to determine if cracks or holes are
present? ......ANSWER......Annually.
An increase in which factor will improve spatial resolution?
......ANSWER......Source to image receptor distance (SID).
What is the most likely reason for the increase in quantum noise on a computed
radiography (CR) image? ......ANSWER......Lower than required milliampere-
seconds (mAs).
Which information in the patient history should prompt the radiographer to
decide against using automatic exposure controls when taking a chest x-ray?
......ANSWER......Emphysema.
Which statement is true regarding exposure indicator and the evaluation of
digital images? ......ANSWER......Exposure indicator must be reviewed with every
image and must fall within the manufacturer's acceptable range.
Which digital communication network is used to store patient billing
information? ......ANSWER......HIS.
Which digital post-processing results in a black background surrounding the
original collimated edges? ......ANSWER......Shuttering.

How does an increase in noise affect the quality of a digital image?
......ANSWER......Contrast is decreased.
Which pathologic condition requires a reduction in exposure factors to produce
an acceptable image? ......ANSWER......Emphysema.
The radiographer is using automatic brightness control during fluoroscopy. What
change in patient exposure should the radiographer expect as the patient size

How can magnification of the heart be reduced when performing a chest x-ray?
......ANSWER......Use a 72-inch source-image-receptor-distance (SID).
What is the function of a rectifier? ......ANSWER......Convert alternating current
to pulsating direct current.
Which change in technical factors is most likely to result in decreased exposure
to the image receptor (IR)? ......ANSWER......Increased grid ratio
Which technique produces a 2 milliroentgens (mR) exposure to an image
receptor plate if 70 kilovolts peak (kVp) at 25 milliampere-seconds (mAs)
produces 1.6 mR? ......ANSWER......70 kVp at 31.25 mAs
Consider this anteroposterior (AP) mobile chest image. What will improve the
photographic quality of this image? ......ANSWER......Using a grid
On which system does hospital staff input new orders for radiologic
examinations? ......ANSWER......Hospital information system.

setting on the operating console for the purpose of producing the heat
necessary for thermionic emission? ......ANSWER......Filament circuit
