Modes of Operation Clover Assessment Questions With
Complete Solutions
Decreasing the fluoroscopic field size affects the multi-field
image intensifier by: Correct Answers Increasing spatial
resolution
How does Last Image Hold (LIH) achieve a still image during a
fluoroscopy procedure? Correct Answers LIH enables the last
live image to be displayed when the exposure is terminated
How does multifield intensification affect the field of view?
Correct Answers Multifield intensification decreases the field of
view
How does spot imaging during fluoroscopy affect both spatial
resolution and contrast compared to last image hold? Correct
Answers Increased contrast
Increased spatial resolution
How does spot imaging reduce the possibility of motion
distortion during fluoroscopy procedures? Correct Answers
Shorter exposure times
How is the magnification factor calculated in fluoroscopy?
Correct Answers Full size diameter of the input phosphor /
selected input phosphor diameter = magnification factor
In digital subtraction angiography (DSA), which of the
following occurs after the initial image is taken? Correct
, Answers Contrast is injected and subsequent images are taken
before subtraction occurs
In order to capture a spot image in fluoroscopy, the: Correct
Answers Video-fluoroscopy is stopped and the spot image
button is pushed
In pediatric fluoroscopy, why is the last image hold
recommended over spot imaging? Correct Answers LIH
decreases patient dose
In pulsed fluoroscopy, the fluoroscopic mA value is expressed
as what? Correct Answers Pulse height
In which mode is the x-ray beam turned off and on at set
intervals? Correct Answers Pulsed progressive fluoroscopy
The use of a longer pulse width will result in which two of the
following? Correct Answers Increased patient dose
Increased tube heat
What impact does fluoroscopic frame averaging have on patient
exposure and x-ray tube heat? Correct Answers Frame
averaging has no direct impact on either patient exposure or x-
ray tube heat
What is the magnification factor (MF) of a 12 inch image
intensifier used in the 6 inch mode? Correct Answers 2.0
What is the primary difference between pulsed and intermittent
fluoroscopy? Correct Answers Intermittent fluoroscopy has the
