Flouro Overview RTBC Questions With Complete Solutions
A cost effective feature of a digital, flat panel fluoroscopic
system that positions the x-ray tube above the patient during
fluoroscopy, is that the system designs typically: Correct
Answers Use a single digital detector for both radiography and
fluoroscopy
A major distinction between digital and flat panel fluoroscopy
system designs is the position of the Correct Answers
Fluoroscopic x-ray tube

of Milliamperage doses for continuous fluoroscopy? Correct
Answers Low range from 0.5 to 5.0 mA
Digital flat panel detectors used for fluoroscopy are: Correct
Answers Indirect in design and use a scintillating phosphor
Digital fluoroscopic systems use Correct Answers A pulsed,
intermittent x-ray exposure sequence
Electronically, the functional unit of digital fluoroscopic
detectors is the Correct Answers Detector element (DEL)
, Fluoroscopic digital flat panel detectors electronically combine
detector elements into multiple-units through a process known
as: Correct Answers Binning
Fluoroscopic grids used for pediatric studies generally feature:
Correct Answers Lower grid ratios with carbon-fiber
interspacing
