Learning about x-rays
Question | Answer |
---|---|
What is the use of x-rays? | X-rays is use to examine components of the teeth and surrounding tissues that cannot be viewed in any other way |
ALARA | As Low As Reasonably Achievable. |
inherent filter function | function is to screen out most of the longer and less useful wave lengths of radiation |
central beam function | is used to expose the x-ray film |
position-indicator device function | To guide and limit the amount of radiation |
target film distance (TFD) definition | is the distance from the source of the x-ray to the object being radiographed |
Dental x-ray units usually operate in the range of what? | 7.5, 10 to 15 mA |
kilovoltage function | used to determine the quality of the central beam |
radiolucent definition | describe less dense tissues and materials that do permit the x-ray to pass through onto the dental film |
radiopaque tissue definition | dense structures that do not permit the passage of x-ray through them onto the film |
collimator function | reduce the size of the x-ray beam and to reduce the amount of radiation to the patient |
