milliammeter (mA) - ANSWER: determines the number of electros available to produce x-rays
7-15mA
kilovolt peak (kVp) - ANSWER: force used to move electrons
60-90kVp
tube head - ANSWER: houses mechanical, electrical, and safety components
extension (support) arm - ANSWER: allows for placement of position indicating device and houses
electrical cords that connect the control panel and tube head
position indicating device (PID) - ANSWER: aims the x-rays
round or rectangular
reduces amount of tissue exposed to x-rays
central rays (CR) - ANSWER: x-rays in the center of the useful beam
collimator - ANSWER: lead washer that restricts the size of the x-ray beam
located within the PID
density - ANSWER: amount of light transmitted through the film
dark films have higher density than light films
contrast - ANSWER: difference between shades of the radiograph
short-scale contrast - ANSWER: few gray shades
many black and white shades
long-scale contrast - ANSWER: many gray shades
many black and white shades
definition - ANSWER: detail
how sharp the outline of structures on a radiograph is
exposure - ANSWER: measurement of ionization in air produced by x-rays
absorbed dose - ANSWER: amount of energy deposited in any matter, living or not
dose equivalent - ANSWER: absorbed dose in living tissue
measured in Sv and rems
latent period - ANSWER: period of time before the first clinically observable symptoms occur
four stages of exposure - ANSWER: exposure, latent period, period of injury, recovery period -
acute exposure - ANSWER: produces short-term effects seen within months
chronic exposure - ANSWER: produces long-term effects seen years after exposure
ALARA - ANSWER: as low as reasonably achievable
using the least amount of radiation to get appropriate diagnostic results
artifacts - ANSWER: blemishes or images on the radiograph that are not present in the actual object
, scatter radiation - ANSWER: comes from the patient's head
maximum permissible dose (MPD) - ANSWER: maximum exposure level
50mSv per year - radiation workers
5mSv per year - pregnant workers and general public
1mSv per day
output - ANSWER: amount of radiation a machine produces at the end of the PID
stepwedge - ANSWER: tests the output of an x-ray machine
determines amounts of radiation reaching the film by measurements of film density
tests when to change solutions
lead foil attached to cardboard or tongue depressor
film speed D - ANSWER: Ultra-Speed
slower than F
film speed F - ANSWER: Kodak InSight
faster than D
requires less exposure time
lateral jaw exposure - ANSWER: shows either left or right half of the jaw
latent image - ANSWER: image made on film when expose to x-rays
must be processed to turn into a visible image
coronoid process of the mandible - ANSWER: bone seen on films taken in the far back of a pts mouth
radiopaque
hamular process - ANSWER: spike of bone seen behind the last molar
radiopaque
maxillary tuberosity - ANSWER: rounded portion of bone behind the last tooth
radiopaque
zygoma - ANSWER: portion of the cheek bone
radiopaque
sinus septum - ANSWER: thin bone separating the sinuses
radiopaque
floor of the sinus - ANSWER: lower border of the sinuses
radiopaque
nasal fossa - ANSWER: nasal cavity
radiolucent
median suture - ANSWER: "crack" between roots of maxillary central incisors
area of incomplete fusion
radiolucent
incisive foramen - ANSWER: hole in the bone of the maxilla and between roots of incisors
radiolucent
external oblique ridge - ANSWER: dense white line distal to the last molar and moving across root of
molars
