Fluoroscopy Quiz (Revised) Questions With Complete
Solutions
ABC (Automatic Brightness Control) Correct Answers
maintains the brightness and contrast of the fluoroscopic image
during the procedure.
ADC Correct Answers converts analog data (electrical current)
to digital data (1s and 0s). Each has a set number of bits which
determine image contrast resolution and the size of the image
matrix.
Brightness gain Correct Answers minification gain x flux gain.
Cassette spot filming Correct Answers uses a regular
radiographic cassette, and the tube switches to high mA
radiographic mode.
CCD (charge-coupled device) Correct Answers used for
converting the light image to an electronic image greatly
improves digital imaging.
Charge-Coupled Device (CCD) Correct Answers includes
semiconductor capacitors.
Charge-Coupled Device (CCD) Correct Answers is more
sensitive to the light from the output phosphor; it has a higher
DQE.
, Conversion factor Correct Answers another descriptor of the
overall ability of an image intensifier to create a brighter image,
is measured in cd/m2/mR/s.
Conversion factor Correct Answers is a newer term for
brightness gain and is typically about 1% of the brightness gain
value.
Fiber optic bundle or optical lens system Correct Answers is
used to link or couple the camera or CCD to the output phosphor
of the image intensifier.
Flat-panel detector Correct Answers is capable of reducing the
radiation dose during fluoroscopy by as much as 50%.
Flat-panel detector Correct Answers is easier to move around
and allows better access to the patient during a procedure
because it is significantly less bulky.
Fluoroscopic image Correct Answers is viewed by looking at a
television monitor.
Fluoroscopy Correct Answers allows imaging of anatomy in
motion, or dynamic imaging.
Fluoroscopy Correct Answers uses a continuous beam of x-rays
to create images of the movement of internal structures that can
be viewed on a monitor.
How many lines does a typical high-resolution monitor will
have? Correct Answers 1024 lines
