CORRECT ANSWERS ALREADY PASSED
GRADED A+
◉ Increased receptor exposure factors. Answer: Increased mA,
Increased exposure time, Increased KVP.
◉ SID and beam intensity relationship. Answer: Inverse square law.
◉ Primary factors of radiographic quality. Answer: Receptor
exposure, contrast, spatial resolution, and distortion.
◉ Contrast control. Answer: Primarily controlled by altering the
kVp.
◉ Scatter radiation effect on quality. Answer: Decreased contrast.
◉ Focal spot size change effect. Answer: A change from the small
focal spot to the large focal spot will result in decreased spatial
resolution.
,◉ Object-image receptor distance effect. Answer: An increase in
object-image receptor distance (OID) will result in increased
magnification.
◉ 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.
