X-Ray Operator Practice Questions
Medical Imaging Exam Prep
Radiologic Technician Exam Guide
,collimator definition - correct answers ✔✔A box-like device attached under the tube
housing that allows the limited operator to vary the size of the radiation field (a variable
aperature)
detent - correct answers ✔✔A mechanism that tends to stop a moving part in a specific
location
computed radiography (CR) - correct answers ✔✔Sometimes called "filmless systems"
which produce images via a digital format using computer technology, eliminating the
need for darkrooms
image receptor system (IR) - correct answers ✔✔Consists of the X-ray film and the film
holder, also known as a cassette
central ray - correct answers ✔✔A line in the center of the X-ray beam and
perpendicular to the long axis of the X-ray tube
attenuation - correct answers ✔✔the absorption of x-ray beam by matter
control booth - correct answers ✔✔The portion of the X-ray room that is protected from
scatter radiation and safe during exposures
grid or bucky - correct answers ✔✔A device to protect the film from being fogged by
scatter radiation
remnant (exit) radiation - correct answers ✔✔the resulting beam that exits from the
patient and creates image
, tube port - correct answers ✔✔An opening in the X-ray tube where X-rays that are
traveling in a useful direction exit
scatter radiation - correct answers ✔✔photons that interact with the body's matter and
travel in a different direction
primary radiation - correct answers ✔✔The X-ray beam that leaves the tube and is
unattenuated, except by air
longitudinal - correct answers ✔✔Tube motion along the long axis of the table
transverse - correct answers ✔✔Tube motion across the table, at right angles to
longitudinal
vertical - correct answers ✔✔Tube motion up and down, increasing or decreasing the
distance between the tube and the table
Angle (tilt, roll) - correct answers ✔✔Permits angulation of the tube along the
longitudinal axis of the table
Rotation - correct answers ✔✔Allows the entire tube stand to turn on its axis
X-Ray tube - correct answers ✔✔the source of x-rays
phosphor material - correct answers ✔✔Used in a closed cassette rather than on film to
obtain computed radiography (CR) images
