Radiology Concepts
A technique that shows the crowns of the upper and lower teeth together.
Created when the primary beam interacts with matter
What is secondary radiation
The part that the patient bites on
What is the bite block
This can be used to stabilize a bite block to prevent shifting when taking an x-ray
What is a cotton roll
ALARA stands for
What is As low as reasonably achievable
The measurement of the number of electrons moving through a conductor
What is amperage
The useful beam produced at the target
What is primary radiation
The part that the tubehead aligns with
What is the aiming ring
Which part of the x-ray machine generates the x-ray beams
What is tubehead
What are 3 examples of image receptors
What is film, sensors and phosphor plates
A technique that uses bisecting and paralleling methods to show the complete teeth and supporting bone
What is Periapical
Secondary radiation deflected from its original path
What is scatter radiation
The part that holds all the pieces together
What is the indicator arm
This is the most important responsibility of the operator in dental radiography
What is limiting patient exposure
This restorative material would appear radiolucent on a dental radiograph
What is amalgam
A x-ray is a form of what electromagnetic radiation
What is high-energy
This can be a result of primary, secondary, and scatter radiation
What is biological damage
Which power-source control setting has the shortest wavelength and greatest penetrating power
What is high kilovoltage
What is an advantage of using the paralleling technique to expose dental radiographs
What is images with minimal anatomic distortion
This structure would appear radiopaque on a dental radiograph
What is Bone
This determines the quality of the wavelength of the x-rays and controls the penetrating power of the beam
What is Kilovoltage
This measures the amount of ionizing radiation in the air
What is Roentgen (R)
The time between exposure to ionizing radiation and first symptoms of biologic damage
What is latent period
This is used to hold a sensor, film or phosphor plate when the patient has sensitivity issues and they can't tolerate the XCP.
What is a Snap-A-Ray
When taking and FMX the number of Posterior periapical films
What is 8
