QUESTIONS AND CORRECT ANSWERS
ALREADY PASSED GRADED A+
◉ Motion effect during exposure. Answer: Motion of the patient, the
tube, or the IR during the exposure will result in decreased spatial
resolution.
◉ Quantum mottle appearance. Answer: Finely speckled or grainy
areas.
◉ Cause of quantum mottle in digital imaging. Answer: The mAs
being set too low.
◉ Increase in spatial resolution. Answer: Increase in SID, Decrease
in focal spot size.
◉ High signal to noise ratio image. Answer: Highly detailed, with
very little quantum mottle.
◉ Automatic exposure control termination. Answer: The timer has
gone off.
,◉ Contributing factors for image receptor exposure. Answer: MAS,
KVP, SID.
◉ Digital image processing caution. Answer: Electronic collimation
(masking) should not be used to replace proper radiographic
collimation.
◉ Computed radiography plate reader component. Answer:
Developing solution.
◉ Optimum viewing conditions for radiographic images. Answer:
Low room light level.
◉ Radiograph artifacts. Answer: Marks, exposures, or images on a
radiograph that are not a part of the intended image.
◉ Effect of irradiated tissue on scatter radiation fog. Answer: Scatter
radiation fog increases.
◉ Effective way to reduce scatter radiation fog. Answer: Use a grid
or Bucky.
,◉ Grid use recommendation. Answer: A grid should be employed
when the part thickness is greater than 12 cm.
◉ Technique charts expression. Answer: Based on patient part
measurements obtained using an x-ray caliper and are expressed as
thickness in centimeters.
◉ Matrix size effect on pixel size. Answer: As the matrix size
increases, the pixel size decreases.
◉ Anode heel effect appearance. Answer: The image will be lighter
on the anode end than on the cathode end.
◉ Radiographic quality factor affected by angulation. Answer:
Distortion.
◉ Positive charge part of X-ray tube. Answer: Anode.
◉ Filament circuit function. Answer: Contains the step-down
transformer.
◉ Circuit location of the tube. Answer: Filament circuit, primary
circuit, secondary circuit.
, ◉ Exposure time for 80 mAs at 400 mA. Answer: 0.2 seconds.
◉ Digital image display process. Answer: Histogram analysis.
◉ Contrast resolution effect factor. Answer: Bit depth.
◉ Required document for experimental procedures. Answer:
Informed consent.
◉ Definition of negligence. Answer: The omission of reasonable care
or caution.
◉ Graphic for patient chart. Answer: Used to provide longitudinal
comparisons of temperature, pulse, and blood pressure.
◉ Employer responsibility doctrine. Answer: Doctrine of respondeat
superior.
◉ Interpreter role for non-English-speaking patients. Answer:
Translate only what is said by and to the patient.
◉ Family demands on staff cause. Answer: Fear over the condition of
their relative.
