Radiology Science of radiation as used in medicine.
Radiation Electromagnetic rays that travel as waves of energy through space.
Radiograph Image produced on photosensitive film by exposing film to x-rays and processing.
X-Radiation "X-Ray" High energy ionizing electromagnetic radiation.
Made up of the x-rays that come from the target of the X-Ray tube. AKA:
Primary Radiation
Primary beam or useful beam.
Scatter Radiation Form of radiation produced from any substance being struck by primary radiation.
Seconday Radiation Form of radiation produced from any substance being struck by primary radiation.
Dose Amount of energy absorbed by tissue.
Genetic Effects Radiation effects passed on to future generations through genetic cells.
Somatic Effects (Somatic - "Greek" body Effecs of radiation causeing illness and responsible for poor health.
illness)
Radiographic film that show the interproximal areas, crowns of the maxillary
Bitewing Radiograph (BWX)
and mandibular teeth on the same film.
Central Beam Central portion of the primary beam of radiation.

Component affixed to the tube head that helps align the patient and film when
Cylinder
positioning film.
The central beam misses the center of the film and produces a blank area
Cone Cut
cutting off the edge of the film.
Electromagnetic Radiation Series of electromagnetic waves.
Elongation Describes distortion of image; appears longer than actuality.
Extraoral X-ray film packet placed outside the oral cavity during exposure.
Foreshortening Distortion of image; appears shorter than actuality.
Horizontal Side to side motion.
Intraoral Film packet placed inside oral cavity during exposure.
Ionizing Radiation Radiation that produces ionization, resulting in harmful effects.
Ioning Radiation (Ionizing - turning an ...
atom into an ion by adding or taking away
particles.)
Unit of electromotive force, equal to 1000 volts, drives electric current through
Kilovolt
circuit.
Latent Period Time between exposure to ionizing radiation and the appearance of symptoms
Lead Apron Heavy lead lined, plastic apron placed over patient for protection during x-rays.
Lead lined wall or movable shield for students/staff to stand behind while
Lead Shield
exposing x-rays.
One thousandth (1/1000) of an ampere, a unit of measurement used to describe
Milliampere (mA)
intensity of electric current.
Midsagittal Plane Imaginary line dividing tooth longitudinally into two equal halves.
Occlusal Plane Plane between upper and lower teeth.
Occlusal X-ray Radiographs produced by placing film along the occlusal plane.
Produces extraoral radiograph that shows both dental arches and TMJ's.
Panoramic Radiograph
Machine rotates around patient to produce radiography on one film.
Shows all structures of teeth in a given area, with all parts of adjacent tissues
Periapical Radiograph
and oral structures.
"Cylinder" or "Cone" Part of x-ray machine aligned with the film during exposure.
Position Indicator Device (PID)
maybe cylindrical (larger beam) or rectangular (limits size of beam).
Dark areas of film after exposure shows structures that radiation can easily pass
Radioluscent through on a film. For example: air, soft tissue, abscesses, tooth decay and dental
pulp.
White or light gray areas of film after expusure shows structures that radiation
Radiopaque does NOT easily pass through on a film. Examples: Metal, tooth enamel, dense
bone
Vertical Up and down motion
