OHIO GXMO EXAM FULL STUDY GUIDE | ALL QUESTIONS AND
CORRECT ANSWERS (VERIFIED ANSWERS) | LATEST EXAM 2025 |
ALREADY GRADED A+
Contrast -
Answer-The difference between any two adjacent portions of the image
Attenuation -
Answer-Absorption of the X-ray beam by matter
Scatter radiation -
Answer-Partof the X-ray beam that scatters in opposite direction, from the patient. Has
less energy than primary beam. Not easily controlled
Detent -
Answer-Special mechanism that stops the X-ray tube in a specific location.
Trendelenburgs position -
Answer-Flat on back with head lower 15 degrees
Grid -
Answer-Device that absorbs most of the scatter radiation coming off pt, preventing it from
reaching IR. Increases pt exposure.
Floating tabletop -
Answer-Allows the top of X-ray table to move independently, which makes it easier to
align body part
Bucky -
Answer-Grid and pull out tray to hold the IR plate and center it to Central ray
Stationary grid -
Answer-Grid that does not move during exposure
When to use a grid? -
Answer-10-12 cm or more in thickness or when kVp greater than 60
Upright cassette holder *UPRIGHT BUCKY* -
Answer-Hold IR in upright position. Mounted on wall and able to be adjusted for height at
40 or 72 SID
Control console *panel* -
Answer-Where the limited operator sets exposure factors and Initiates the exposure
Transformer cabinet -
, Answer-Used to produce high voltage required for X-ray production
Fundamental rad safety -
Answer-The potential hazard is greater for the limited operator than the pt because the
limited operator is in frequent daily contact
Sources of radiation -
Answer-X-ray tube and any matter that is in the path of the X- ray beam
Principle source of scatter? -
Answer-The patient
